Actually, I had problems with a DMF on my 2005 Golf TDI and decided to go with a lightened, 17 pound, SMF...and love it! Didn't really notice any more vibration and the car is quite a bit peppier and that was about 100,000 miles ago.

I changed out a dual mass flywheel on a 2001 Ford F-250 Superduty 7.3 diesel and it drove flawlessly. It was half the cost of going back with complete dual mass assembly and parts were easier to source. Clutch pedal feel and engaging was awesome.

I just saw the thumbnail and came to say YES! you should always do a conversion to single mass, even on a 2.5tdi :D

If it’s a diesel ABSOLUTELY DO NOT CHANGE FROM DMF TO A SMF The torque on a Diesel engine will destroy it within 1 year

Thanks, great video👍🏽 My Passat Alltrack B7 2012 have been making a lot of sound now for almost 3 year. I thought the dual mass flywheel would break sooner so I bought a SMF 2 years ago. I have been using the car for moving trailers and some off-road driving. The reason I want to change for single mass is that you have better contact and control over the clutch. So depends like you say if you want comfort or better control over your car. SMF will also last longer if you abuse the car. Great video👍🏽👍🏽👍🏽

I was 30 dollars away from getting a solid conversion kit because I already had clutch, pressure plate, etc. for the dual mass and thought single mass was better. Although I own G35 and love all the HP and torque I can get, it's also a daily driver so thank you for the honest opinion. For me the $30 is worth it. I'm sticking with the dual mass. But if I had the chance to restart before I bought all these parts, I would go single mass for sure. #lessmoney #more torque #areasontofixtransmissions LOL

very useful information more than 90% of videos on youtube!

2004 Audi B6 S4 w/ 115k mi. Thinking it’s time to upgrade my clutch to a performance clutch and upgrade the flywheel to LWFW thanks for all the information it was much needed.

Very informative. Thanks to you I will definitely not do the conversion from dual to single fw.

Thanks for the great informative video. I don't understand anything about cars though i have been driving them for 25+ yrs. Recently had a clutch going week on my Scoda Laura 2 ltr diesel, to save costs the mechanic recommended changing from Dual to Single Mass FW along with a new clutch. Post changes, the car has got more pep, drives smooth overall noise is substantially low. No vibrations at all but milage has dropped don't know if he re-tuned the engine to make it feel peppier and a fuel guzzler.

Thanks, very knowledgeable information

Thanks for the info .... Needed !

Excellent video mate very informative thank you very much 👍👍👍

This video was for me. Nissan X trail t30 dci. Stock DMF got buggy after 80k miles. I became rattly. Luk DMF was much costly. So my mechanic weld binded DMF plates into single piece. Put in a spring clutch. It costed me 250$ . But it a mess. Horrific vibrations. Can't drop rpm in higher gears. Had to pull my car at upshiftes, more frequent downshifts. Result way more fuel consumption. And day night difference in smootnes and NVH . Hardly managed to drive 10k miles. Then i bought luk DMF kit . Flywheel + clutch plate+ pressure plate+ bearing . Its heaven now. Buttery ride. Totally different car and drive quality. Once one has tasted a DMF, i bet he cant go back to normal. Yes be ready to break your bank every 100k kms. But thats how it goes.

got my mondeo st tdci with smf conversion and im well happy typical rattle smf noise at idle but thats it no vibration or shifting probs it drives great

Great video

best vid I found on this, thank you

Very helpful video, just bought a 2006 infinity g35 6 speed manual coupe that has a dual mass fly wheel and plan to do the conversion in the next couple months!

Picked my car up just half an hr ago after having a single mass flywheel fitted. It a 2007 Ford Focus 2.0 litre Turbo diesel. Due to low emission law in London England where I live. I can only keep the car until October next year. So YES! It's noisier and vibrates more than before. In fact it sounds more like diesel engines used to!! Slightly industrial/commercial. But hey it was much much cheaper to fix. I can live with this easily for a year! Cost me £380 total Inc parts. That's a local back street mechanic who I've know for years.

bought a smf kit for my ford transit ,this kit actually uses a replacement crank pully damper so hopefully should be ok ,thanks for your film.

An excellent video. Cost of aftermarket flywheels isn't always a reason to covert. DUK makes a good DMF that's half the cost of solid, for my car, with aluminum flywheels 3 to 4X the cost. (Scale of production?) I'd attribute crankshaft and tranny fails more to driving style, since these guys are often the same who replace clutches more often than most of us replace brake pads. The lighter weight allows the engine to rev quicker; better performance. As you say, DMF smooth out engine pulses, springs plus an extra 50 or 60% in weight. They also have a small amount of "float" (angular deflection) which might make for smoother engagement.

I had clarity between the two and especially with the modification / conversion. All I can say is that this Dual Mass is expensive and does not last. I am sitting with exactly this choice to make and I know now that I just need R8000 to buy a new flywheel if I want to use my car again.😭 Thank u so much

In trucks the reason you give is correct. In cars it's so the manufacturers can fit weaker components and save money. They also make more money on flywheel replacements too!

Great video 👍

Great and educating

Thanx love the info

I know from experience, on certain 911 cars, specifically GT cars... The GR3 RS cars as opposed to the regular GT3, one of the major differences is the single mass flywheel. Porsche has engineered their carsto run on a SMF. The DMF is installed for a bit more civility from factory, but the SMF gets the most out of the engine.

I wanted the best of both worlds. A SMF but one that would not make as much noise as a light weight SMF. But even I was going to do the conversion I did lots of research and decided if I do the conversion I would also add a fluidampr to help with providing durability by controlling that extra torsional vibration which also causes more noise. Another benefit to the fluidampr controlling vibration is allowing lost torque and horsepower to be released while providing that extra efficiency. It also helps with the chatter that causes the extra noise. I wont say it gets rid of that chattering and noise all the way. Although a Fluidampr refines that clunky engine/drivetrain combination to something smoother. Another plus is that the Fluidampr got rid of a good deal of noise that the motors mounts added. Shifting also felt smoother at part throttle. Is it a not a mod that you can must have? Is it something that is totally worth it as different hardware setups make it more noticed? I think the advantages are worth it. In my opinion if youre going that SMF route and going for more power, why not add something that will add an extra layer of "bullet proofness". That being said. When I wrote above I wanted the best of both worlds. Ringer Racing which sells Clutch Masters clutch kits and Clutch Masters SMF's. Ringer Racing offers a 23lb SMF. This is heavier than the average SMF by around 7-9lbs. Now I know many will say they want to shed as much weight as possible from their cars. However that extra 7-9lbs coupled with a Fluidampr gets rid of around 65-75% of that engine chattering and noise. Ringer Racing offers that Clutch Master 23lb SMF for an extra $57.00. However when you go on Clutch Masters website they do not mention anything about a 23lb SMF or even show that they offer it. It seems that Ringer Racing has an exclusive on a Clutch Master 23lb SMF. However when I contacted Clutch Masters. I was told yes they make that 23lb SMF for Ringer Racing. But Ringer Racing doesnt have an exclusive on it. The reason Clutch Masters doesnt advertise it is because most people want a SMF as light as possible. Although if someone asks Clutch Masters or one of their dealers for that 23lb SMF. Clutch Masters or any of their dealers will be able to provide one. It costs the same as their lighter SMF. That 23lb SMF makes a huge difference over Clutch Masters lighter SMF. And if you add a fluidampr along with that 23lb SMF. All I can say is its almost perfect

The VWs that are failing are due to increased clamping loads from the uprated pressure plate. The additional force is causing failure of the crankshaft thrust bearing on some MK7 Golf cars.

Honestly I've had 4 Mondeos now and I converted one to a smf and it was never right after vibrated like fook. the car I'm driving now mk4 Mondeo 1.6 d clutch started to make noise when I pushed pedal down so I presumed the clutch was worn while hearing no dmf noise so got a clutch kit for it and had someone fit it for me to be told after car was finnished that someone had put a solid flywheel into this aswell and the noise was actually worse after job was done to be told that the solid flywheel vibrations has dammaged the input bearing in my gearbox so long story short second hand box from breakers and new dmf and another mechanical bill, lesson learned badly ! if the car comes with a dmf never ever fit a smf not unless you want a very expensive bill down the road . Cheers.

and thats why i got a fliudampr when i did the conversion :)

Most people can't tell when they're driving on 3 wheels let alone feel the difference between solid and DMF's. In theory, yes fine, but practically speaking not worth the added complexity and cost. And I'm all for improvements, but they have to be worth it.

Informative.

very good one more registered and will like

If you want your gearbox and crank to fail fit a smf. If its got a dmf it's there for a reason kids!!

Now gonna have smf fitted to my st tdci il let u know how it goes and how it runs

Now I know why people really liked the smoothness of my 2021 GTI manual. I like it. Though I wonder if its design has anything to do with clutch pedal travel. I don't feel it engage until almost the top of my pedal travel.

The problem with the transmission or gear box when they install the solid flywheel they give it more abuse they are made for that harder gear changes or dumping the clutch more puts strain on the gearbox if you upgrade your gear box too then it has no affect and the vibration you are talking about I’ve done this and have not seen a difference in the car on start up or driving and as for this happening in vw since I bought the car 5 years ago it hasn’t missed a change of gears

Maybe a fluid dampr-brand harmonic damper would reduce vibration if going with a single-mass flywheel?

This is my experiences from doing the conversion from BMF to SMF. I only took the vehicle on one trip yet, 2 hour one way, so it could change, I dont know if the clutch disc needs to get broke in. I have a 2006 Pajero/Montero 2.8L Diesel 5 speed manual. I put in a flywheel and clutch from the Montero Sport, has the same engine and trans. but with a SMF. Everything feels fine except for 2 and 3 gear I needed to have the rpms close to 2000 or else I would get a vibration and shimmy. But it depended on how much torque the engine was making because it was different if I was going up a hill or going flat. So what my conclusion is that the 2 and 3rd gear have too low of a ratio for the engine HP at low rpm 1200-1500. once the engine is going faster, around 2000, it is producing more hp and the vibration goes away. Would like to hear from other Pajero owners what was your experience? One thing I noticed is that the next model year Pajero 2007 they eliminated the DMF and went with a SMF. And from what I can tell the engine and the trans. are the same. I saw that the clutch disc has bigger springs than the one I put in. probably to mimic the DMF. however I had already purchased the parts for mine or else I would have tried to put that one in.

Went to a single mass flywheel on my T-5 for my Mustang. I actually like it. I drive pretty aggressively, anyway, and the extra mass handles the torque curve a lot better. Now... the vibrations switching through lower gears HAS broken a few small plastic/aluminum parts that were older and needed replacing (injector seats, LSD spring, u-joints) But they were going to go eventually, and this gave me an excuse to upgrade them. The dual mass was nice, but the single mass has been a lot more fun, and the noises add some character to the car.

Newer had problem with single mass conversion on remap with 200hp pluss just good kevlar clutch

Has anyone here on this post converted DMF to SMF on a 6-cylinder or V-8 engine with a manual transmission? Were there any noticeable differences in shaking/vibrations/ noises at start up, shifting gears or shutting down the engine? I'm considering the conversion in a Mercedes C240 with a 6-speed tranny.

Thank you for this video, My D40 has a bit of a clutch problem and I was recommended to switch to single... I guess I'll stick with double! Thank you for your free expertise!

it is normal when you converting from dual to single, when im not moving or slow speed, when i press the gas in normal speed the engien feels like moving similar like,, when you have old crazy mountings. but the moutings are in good condition... to dont feel the engine moving, i need to press the gas really slow similar like im playing with a clutch, but if im going for exmp 60/80km i dont need to press the gas slow strange

Ive got a Sachs flywheel sm and it sounds like a boatmotor when releasing clutch clowly in gear

I have a 2014 ford focus st it has a dual mass flywheel and i got a single mass but it not fit but the store is saying that thats the size

Great video thank you. I've been 'pushing' my clutch by towing heavy loads, even pushing the loads in reverse gear. My clutch started to smoke and smell and now it judders when I pull away. Can I upgrade my DMF and clutch kit to a heavier duty version, to extend the life with the heavy loads?

Damn, I'm replacing my clutch because it's started to slip a bit and never knew i had a dual-mass flywheel (or that they existed!). I'm quite gentle driving but i would have been even more so had i known 😮 Well i didn't buy the flywheel because it was another $350. So I'll inspect it and see.ty

Dual mass to single on my 150hp diesel. 100k km since install. Other then all the noice and some more vibrations, I would much rather go with the single flywheel. Much stronger and last for a longer time, changing at a garage costed like 1.7k $. So I would not want to have a dual mass that might fail again.

I have an 04 Lexus is300 is it worth it and mainly reliable to do the conversion????

A 16. 5 year old golf plus 1.9tdi with a whine in 3rd at 100k. Has developed to a whine in 4th and 5th also now at 130k. Also noted since gearbox oil change last week, drained only 1.2 litres of grey stink. Replaced with 1 Litre of new gearbox oil 80w as recommended and added half litre of lucas oil stabilizer. The gearbox is annoyingly louder and shifter stick wobbles in 4th only, with no revs but steady with revs. I'm at the point of watching and reading all I can. Is it gearbox? Is it clutch? Is it both? Against the value of car, the money in my bank and what I'd be throwing away (it just flew its 3rd mot in a row with zero advisables so it's a great car other than this issue and I have fully serviced it the last few weekends) is it worth throwing away for another cheap car or do I pay about £350 for a single mass clutch conversion and gearbox recon kit? I'm not a mechanic but it's worth it to me to take 2 or 3 days slowly working through YT videos. I also have a pal who has a 6ton press and I'm sure he would help with the recon of gearbox. Obviously I'd be hoping that when we open up the gearbox, it's obvious it's in good shape and only the clutch was the problem. A bit like building, you don't know until you take it apart or put a shovel in the ground. The gears I'm sure are fine, probably needs the bearings replaced? I'd then know I've got a great solid (if old) motor under me. Also being a VW it's only another 5 or so years from starting to become retro and cool (something VW motors always become no matter how ugly, and boy is the plus fugly!) I could easily splurge 1k or 1.5k and still end up with a car that needs more work soon after. I guess it's a no brainer. The cars worth fu9k all now.

As far as Mk6 Volkswagens, I've had a SMF for about a year now. The throttle response was much better and had much less rev hang, but the additional gear noise on and off throttle is so off-putting. Going back to dual mass shortly, I'll just have to deal with the rev hang.

You are absolutely correct I wish I would have never changed out my dumbass for a single light white aluminum fly wheel in my 370 Z very hard to drive in traffic very fun to drive in the corners but I wish I would’ve never done it not worth it the ride quality does suffer

Hi my car vibrates only when engine is hot when cold no vibration can that be dmf thanks

If you go single mass flywheel get a liquid damper crank pully (regularly a steel pulley with no crank walk preventing abilities

Hey, nice video. You explained everything in detail. I would like to know if it is possible in a hyundai santa fe 2.0 DM model of 2013-17. The price for a new OEM flywheel is approximately 2700$ which is too much. What could be the cons and is there any way to repair the old flywheel in any way? Awaiting your reply.

Hello, is it good to put on my bmw e46 318D.116KS single mass flywheel?

I got a 2016 vw gli should I do a dmf or a smf ?

Is the front-end of a '77 Jeep Cherokee?

So how and where do you weld it together?

Good day, Great video, I'm converting my DMF to a single mass on a Ssangyong Korando 2011 Diesel SUV 2.0 e-XDi - must I change the clutch plate to one with springs or leave the clutch also solid?

My OEM dual mass clutch just failed on my 2012 v6 Mustang. I replaced it with a single mass clutch, and it is definitely lounder and something you have to get used to.

I have a TDI GOLF 2013 Stage 2+ EGR+DPF delete. I switched to a single mass DKM clutch kit Stage 2 to handle more torque but as you said 1 year later I had transmission issues and now I need to reinstall the Dual mass Clutch. I will go with the Sachs Performance dual mass flywheel organic clutch. I have to change my transmission and I didn't know that the single mass would make such a big mess because of all the vibrations transfer to the transmission.

So this is a little weird but would you recommend going from single to due mass The reason I ask is I have done this as I went from a 5 speed to a 6 speed

Has anyone done the conversion on a E90 320d or any BMW with M47 Diesel engine?. Im really on a tight budget, so the solid mass kit is very tempting as it is less than half the price of a DMF kit.

Both a VW , 1.6 TDI 2014/B7 drove 30K and the transmision failed, the noise from transmision never stopped during driving only at 70miles/hr the noise stopped and when my mechanic change the transmision notice that the car was converted, the worst part is that in UK, Euro car parts and GSF would send t'same single mass flywheel, only the VW dealer could provide the right one and as a shock dual mass from dealer was cheaper than single mass from the usual parts provider for my mechanic, stay away from single mass if you can it cost me a fortune to change everythyng, all engine mounts, both driveshaft, gear box, clutch +dual mass flywheel, and there is no guaratee yet that my engine would last as much as it should!

My Alfa had an F40 gearbox and an SMF conversion. 1st and 2nd gear brass inner friction rings broke in half somewhere during 16000miles. I was really surprised at the damage.

One of the least mentioned features of dmf as opposed to smf is that u can rev it for a lot longer and harder and Rmp drops a lot slower, allowing for a lot less drive on the gas pedal once u are high enough, smf drops rpm a lot faster and therefore u need to be quick to either drop gears, or just put the car into neutral before approaching the obstacle.

the DMF isn't about vibration, it is about the torque in diesels hence the springs allowing rotation movement.

I am thinking of converting my dual Mass flywheel to single Mass Flywheel on Toyota corolla professional d4d 2.0 diesel advance 2007 1ad

Thank you for info, i am curious about failing noise of dual mass flywhell

Petrol engine, yeah can make a difference esp if it's lighter, for diesels don't ever ;)

Everytime he touched the flyqheel i was like who tf tryna make beats

I have an question. My clutch was slipping on my 350z soo I changed the clutch on it. Not even 1200km or 750 miles and I get shudder when taking off in 1st gear when it is hot. Need to keep the RPM's littel bit more up then usual to take off without any shudder. It is not super bad but is noticeable. Is it an bad flywheel or mybe not ? I have no noises of an bad flywheel, am just concerned if the flywheel is mybe on its way out. Edit* My car has an Dual mass flywheel.

Hello thank you for a great video. I should have watched it before switching to a single mass flywheel, my engine or transmission vibrates miserably and makes loud noise during 5th and 6th Gear around 2000 - 2100 RPMs is that normal with the single Mass flywheel? It drives fine under 1900 and over 2,100 RPMs. Clutch engages perfectly transmission shift perfectly. Thank you for your response

what is the price difference SMF vs DMF?

I think you're miscommunicating a concept of what the dual mask does it does not cancel out vibration. It reduces torque hammering on the drivetrain/transmission+ by the low RPM of a turbo diesel or turbo engine's output. Whether the drivetrain sees drag and slows the engine down and puts feedback through the wheels through the axles to the transmission to the actual crankshaft those springs are meant to buffer that force in RPM rate change

Weld the DMF to a solid flywheel

Got to 3:20 and thought. Yep that's all I needed to hear!

I replaced my entire clutch kit on an Opel Vectra C 1.9 CDTI. It had a dual mass flywheel, and put in a new dual mass flywheel. When cold outside, both the old and the new one used to rattle. It fixed the vibration when changing gears, the ride is nice and smooth when it warms up. I have to say it only does this when low temperatures ( under 10 C ) When it's hot outside, no problem at all. Should I worry about this? Is this normal? It is a new LUK Kit.

Don't replace LUK crapp for new LUK crapp, get a decent DMF.. Sachs, Exedy.. and a good tune, not agressive from idle, that will destroy a DMF in 30000km

How about welding in the masses together on a DMF ?

I saw another video where they explained what happened when they put a SMF on a 2015 TDI. Starting in 2010, the 02Q treans used steel synchros. Those can't take the high vibration passed on by the SMF so they end up breaking. Also the shift forks for the high gears are weak compared to the old 5 spd trans that came in the earlier TDI engines. That new noise that you hear at idle, especially with the A/C running is gear slap inside the trans in neutral. kzfaq.info/get/bejne/fNClgJOq38jcaHk.html

Engines have run for more than one hundred years without that pointless dual mass crap.

I regret mine. To much chatter

Excellent video. Please use a different table next time. The continuous "BONGING" every time you touched one of the two parts was distracting.

Dual mass flywheels are for cars with shitty engines, such as 4 cylinder diesels or ridiculous 3 cylinder engines that the tree huggers have forced on us.

You forgot to list the biggest benefit of the dual mass flywheel: They hold the rpm's while you take your time shifting. That alone is worth GOLD, I would never convert to single mass, would be like raping my BMW E36 M3, screw that.
