I don't usually write comments but this was incredibly helpful, I don't know anything about nitro and I was able to completely disassemble the engine. The tutorial was very easy to follow and has aged well

This is the best nitro assembly video on youtube hands down.

Very informative video. The only thing I want to mention is at 5:13, it's worth noting that there is a small shim/washer that must not get lost that is on the end of the starter shaft.Also at 17:53, there wasn't that washer reinstalled, I don't know the importance of it,but wanted to point it out to others.And at 13:12, there is a oil hole on the bottom of the rod, it is on one side not in the middle, that side needs to face the carburetor to get lubrication.

Just bought a TMaxx and having issues. Fantastic video to show how these things are put together. Perfect pace to hold my interest and perfectly thorough at the same time! Thank you!!! Subscribed

i was given a 2.5 tmaxx that had sat for about 8 years with no after run oil, crankshaft/intake valve was totally rusted and locked in the block....used some gun oil and channel locks to work the crank free....could not remove the sleeve so i could not fully disassemble...flushed it with oil and worked the crank around to the point it would freewheel nicely(about 40 minutes) and slapped it back together. Started and ran like a champ!

Very nice Jason. Very informative for people that aren't familiar with nitro engines. Nice work!

Thanks for the video. I just got my 4 tec runing after 8 years of siting still and was able to get a better starter on it.

Always nice to wake up and see a new video by DEH while getting ready for school

Thanks for the vid, great help in restoring a 2003 nitro rustler the engine hadn't ran in almost 13 years. Had dremel off a lot of rust and corrosion and replace the bearings but runs like new now 👌👌 keep it up

Your videos are so informative, now I can learn new thing about my hobby without searching all over the internet !

Thank you. Your video helped my completely tear down my old Tamiya RC car engine for inspection and cleaning

Hey Jason, this is a great video on rebuilding a nitro. Also another good cleaner for these engines is automotive carb cleaner it breaks down the old oil and nitro really good.

Awesome video Jason! Thanks for taking the time to film it.

Great video! You showed the orientation of the piston inside the sleeve! No one ever shows this!

Cool video buddy and i dont even own a nitro but i watched it to the end all the same. Be proud of yourself not many peeps interest me enough to keep me hooked on a subject id normally just skip by

Great video, helped me to get through my Vintage Kyosho GT engine strip

Very well done. Thanks for the step by step, might have to do this soon.

Excellent work! Thanks for posting!!!

Thank you for this video. It helped me take my nitro rustler engine out! :)

Awesome video! I’m about to rebuild mine and this video was a huge help!

Amazing. If it was one dude I know I could get the information I wanted and needed . It was you . Great video and I really do appreciate the help. I picked up a e Revo 3.3 nitro 1/8 scale she's beautiful and I hope this helps me get her started . I'm very egar to gut her out and making some noise.

man I watch all the videos you make. you helped me when I needed to rebuild my gearbox on my bandit vxl those videos really helped. this one is awesome to I am going to watch this when I need to take my 3.3 engine apart keep making more videos, your gifted so keep it up thanks again.

Awesome video. Love the way you explain everything in detail.

Nice work- excellent vid!!

Thankyou so much!! This helped LOTS!!!

Thanks a lot your video help me out in getting mine running again your video two thumbs up thanks again

Very good video! Thanks for posting.

thank you Jason for making this video ! this will be very helpful in my near future lol

Excellent video and clear voice

Great video!

Great Video! Helped me a lot with my old Hpi Rush! :D

Damn you made that look so easy, I’ve never tried to rebuild/disassemble a nitro engine as I’ve never needed to. But I just bought a Jato with a 2.5 that could possibly use a rebuild and cleaning, and this info on disassembling them will prove invaluable. I only hope it’s in as good shape as that one is. If not, it’s getting upgraded to another, a 3.3 trade up from Traxxas would be just fine.

Nice work. Thanks Bud.

Thanks brotha, great video...I was looking into a t-maxx too much money

WD-40 is a must for these have! Nice video

awesome vid!! Very helpful

Thanks for making this video.

Great vid. Love it!

Only complaints about the TRX 2.5 and 3.3 is the carburetors and bearings. Replace those with the O.S. 11K carb and Avid Race ceramics and the TRX is pretty competitive.

Thank you thank you! Engine would not richen and found out half of the piston was gone!

very well tutorial...thanks man !

Cool vid

This was great!

Just a tip, don't bother taking the flywheel off if you're changing something in the backplate or replacing the piston sleeve and rod. Doing so is risky and a complete waste of time

very informative nice video

Great job

Very helpful

Nice 👍👍👍

Не знал как достать пару, спасибо!

Great video! Will it run without the carb ‘boot’?

What kind of oil should I use for the bearings? I got to completely disassemble my Kyosho GXR-18 because of a crankcase crack. Hope I can save it :(

Thanks for the vid was very helpful just completed my first engine tear down and rebuild and she goes good thanks for the help

Nice video.. I'm barely getting into the rc world I had a few questions before watching this video honestly it answered pretty much A - Z.just was wondering on what or how would it be the best way to figure out the mount position on the engine honestly did not notice it was easier to remove the engine from the top screws than actually removing it from the bottom screws which now I'm having problems with. Witch I'm guessing I did not put them in the right postion since my tmaxx wont go one pressing the throttle. If anyone can give me a some good advice I would appreciate it.

9:00. Be very careful when turning the piston without the sleeve. I’m not blaming anyone, but when I did this the piston came up sideways and smashed about 1mm of the edge of the piston on the inside of the block. If anyone knows where to get a piston ONLY please link it! I need it for a 2.5. I need the piston but not the sleeve.

That’s a Nice clean Traxxas TMaxx 😎

17:25 can you please give a tip on how to get the o-ring for the carb in the groove inside the engine? I'm pulling my hair out with how tricky this is.

Thank you

One of the best videos on how to disassemble a TRX engine. Is the process the same for TRX 3.3?

14:04 is it okay to use lithium white grease if I don’t have wd-40 or after run oil. Could I use PB blasterin instead of wd-40. Which would be the better option compared to lithium white grease or pb blaster. Thanks and thx for putting up such a great detailed video. I’ve had my traxxas t-maxx in the garage for about 4 years collecting dust. When I put it away I knew I had to replace the piston and sleeve. I’ve done this procedure like once 8 years ago so this video was mainly to refresh my memory. I do have we-40 but I’m just curious to know if I could use the above mentioned lubricants. Thanks.

THANKS A LOT

Would be nice if you could explain what “pinch” is because this engine has absolutely no pinch from what I can see and it seems like it will be very hard to start

I am wondering around the clutch shoes, does it have a spring around the clutch shoe, I didn’t see it in your model?

looks like you damage a tooth on the fly wheel with those channel locks..at 6:15

Mean green works awesome for cleaning dirt and grime off. Soke the block with mean green. Then let it sit for a few minutes then you should be able to blow all the gunk off with ease.

I was rebuilding a Traxxas 3.3 motor but one of the crank case? Screws were stripped and that ended pretty quick the motor was about 8-10 years old

Great video.

My traxxas 2.5 was seized up. I used liquid wrench and WD40 I finally all disassembled with the exception of the crankshaft. It spinning freely but it will not come out. It feels like it was pressed onto the bearings. I used a wood block and a rubber mallet and tried tapping on it. Would love to get it out to lube the bearings. Any suggestions???

Why did you not replace that broken cooling head?

What size is the O-ring that goes in the groove where the carburetor seats?

Anyone else gasp when he dropped the crankshaft?

Sir I’m pretty sure that "bar" in the piston is a wrist pin but ion know I’m only 17😭😂

Hey I installed the shaft and it was good. When I installed the sleeve the shaft/ crank was rough to rotate when piston was approaching top end. Do u know why? Thanks

When you take apart a motor and put it back together does it need to go through the break in process again????

When u put that new motor in u should make a video how to break in a nitro motor

try a tooth brush and brake clean or silverwere tray in dishwasher better yet ultra sonic cleaner

Couple things you did not mention there's a bubble on the rod that goes on the crank towards the crank side that should be on the same side as the cutout on the Piston which faces the carburetor of course and you should always check your mesha other than that very nice tutorial

wow thanks i didnt realize nitro engines were 1 cylinder im an electric guy but im thinking about nitro

Hi! I have a question. Can you use a 3.3 engine crankshaft on a 2.5? Both are traxxas.

Best video! Thanks a lot!

You do it superb! I don't talk English very well but I can understand everything you said. Hate people try to use crapy voices to sound cool, make it really hard to understand. I have a question. I have plan to run again a really old traxxas (comes with opel calibra dtm body) it was the cheap/small traxxas engine wen we buy. Can I install the automatic starter in this old traxxas engines? 🙈 🙈 I plan to upgrade electronics as well cause my old beauty drives on planes controller🤣, so I want giromode to a RWD that when finish is plan to run like a truck, is it to bad? 🙈

What did you use to clean it?

Do not use W40 as working lubricator. It is used to help to start moving stuff and cleaning. After short time it dries out leaving no lubrication. If you dont have anything better - few drops of any carengine /lawn mower is still better idea than W40.

Very helpful!

Should always use flywheel puller instead of hammer

Hello, bearings to how be replaced? Thanx...

Has anyone done the Traxxas Power-Up program where you return the engine and they give you another one? Wondering if anyone has been through the process. Otherwise, I’ll need to do this.

I'm starting a channel with the soul purpose of helping people with 1/16 Traxxas vehicles. Haven't made any videos yet, but I will soon

You should get a summit

does it matter if the heat Lopez cracked

One of my buddies gave me this without the engine and extras. Still has transmission. Is it WORTH the TIME AND EFFORT & MONEY to rebuild.???????

i noticed that when i turn the crankshaft the piston kinda sticks a little at one certain spot but goes smoothly the rest is this normal

I'm having some trouble with my 3.3, when I tightened the back plate it gets really hard to turn over, do you know what the problem is? and if so how can I fix it?

What this traxxas chassis model ???

This can be morphed over to the 3.3 as well?

I like to buy these nitro engines and take them apart for fun

The sleeve on mine doesn’t seem to come out

is your right hand okay? it looks funky on camera.

Wait isn't WD 40 a solvent?

My engine got some rust inside its more like just color cause i cant feel any damage to surface does this mean my engine goes to trash or can be still reassembled and used?

You never showed how to remove and to install the O-rings.
