Your work gives great hope to diy mower doctors everywhere! Thanks for the videos!

I've used gasket making stuff on alot of equipment. I've even used it on cars. It definitely works good for quick fixes. So for you to use it on a small engine in my opinion was a perfect was to repair the mower. The main thing is to do it the proper way by letting it set up which you did. Can't wait for the outcome video on this project. Keep up the educational videos. I've learned alot from you. Thank you Good sir

Thanks for uploading these videos. All those hours of work to show how to repair these mowers.

Thank you for making this video. I did this to my mower and followed your steps! You saved my mower!

Form a Gasket is _all_ you need. I have yet used a gasket for the sump. Approximately 40-50 engines have yet to leak. Fact. Good video sir.

I definitely believe that making your own gasket is a better option due to this engine. Since oil leaks are common problems with Kohler it probably means that their gaskets aren’t high quality. Making your own gasket will most likely last longer

the right stuff gasket maker has saved me more times than I could remember in the automotive field I am in

Gasket and seal are like $18 combined. Good video explaining the steps to dissemble and reassemble.

Very helpful, thanks man 👍🏼 now I know how to fix my lawnmower

I’ve used gasket maker on mower engine sumps many times with great results. The key is to let it cure before torquing, the end play is close enough and not that crucial. Much better seal than a paper gasket for sure.

Looks good, I like that round scraper, never seen one before.

I usually use a product called " The Right Stuff" It is a gasket maker and I have never had a failure using it, however it is a little expensive. Thanks for the video.

I would have bought a new gasket…. but, that’s largely due to lack of experience. I have some red high temp RTV in the garage. After seeing this I’m sure I’ll give it a try. The key, as you’ve pointed out, is to allow the gasket time to dry before torquing. Another video and another lesson learned. Cheers

Like so many of the other folks commenting, I would have used the gasket, but that's because I just have not had good luck with the tube stuff. That rust on the deck however would drive me crazy. I'd be going neanderthal on it with a sand blaster and paint. Dirt and grime don't bother me but for some reason rust just bugs me, especially that much rust.

That is almost the exact same mower I have, except mine is a Lawn Boy. Got the Kohler motor on it. One thing I like about the Lawn Boy version is its rear wheel drive instead of front wheel drive. Front wheel drive ones suck cause they don't get as good traction.

I like to use a thin application of Threebond 1184 in place of gaskets in many applications. I apply to both surfaces and support the surfaces horizontally until the 1184 sets up. It's self-leveling, so it does a great job of replacing a gasket and I don't necessarily need to assemble parts within a certain amount of time. I can let it set up overnight at room temp or place it in a warmer area (on top of a boiler or in front of an electric heater are two places I've done this) and it'll set up in a couple hours or less. I apply a small amount of oil to one surface before assembling so I can pull the assembly apart later if desired. I've used 30 weight motor oil as well as assembly lube for this. Assembly lube is thicker and will adhere to a surface that is not horizontal a bit better if necessary.

I knew your cleaning ability would improve with practice. And boy howdy does this mower need TLC.

I've never come across this, but I also don't work on as many lawnmowers as I'd like to.. If I do see this, I might have to give it a shot. I like the make your own gasket stuff instead of waiting for one to come in.

It all depends upon the brand of lawnmower engine,my dads Honda GSV190 engine has RTV sealant applied to the mating surfaces for the crankcase from the factory but with my Briggs and Stratton powered Supa Swift lawnmower the engine is fitted with a 0.15mm thick crankcase gasket which is a standard gasket but Briggs and Stratton do have different sized select fit gaskets to shim the crankcase in order to maintain the correct amount of crankshaft end float inside of the engine. Shims are also available for that purpose as well !

I really like the gasket maker as well

I use an anaerobic sealant. This stuff is brilliant. Apply to one surface, then bolt together to specified torque. It doesn't leak. I've been using it on Euro cars for years. Last car I used it on was my own, when I replaced the left rear axle. To remove, replace these on some Mercedes cars, you need to remove the diff cover after draining the oil. No paper, cork, or neoprene gaskets here. Scourer to remove old sealant, clean with brake cleaner, apply sealant, bolt into place, fill with oil. Job done.

You did great... whenever use the gasket maker and sale it!! Save as much money as possible what the customers won't know won't hurt em... it takes money to make money...

I am with ya buddy, there are times to use the stock gasket and times when you are inviting failure to dinner if you do.

I would of use the gasket maker myself. Great video as always my friend 🙏👍🙏👍🙏

Some engine need the gasket for the clearance of the crankshaft. Went over a vtwin Kohler where they did exactly as you and it seized the engine from the lack of clearance

I use a razer blade to scrape gaskets off and don't worry to much about surface scratches I've made as long as they are not deep , gasket maker is good but you can also replace the gasket and use silicone sealant (RTV) rated for heat and oil / fuel on both sides of gasket a light coat will make it stick in place and fill in any imperfections in the mating surfaces but like you said let it set up before you torque the bolts either way will work as long as it is sealed in the end

I’ve definitely used gasket maker on my lawnboys, I thought It had lost power and or compression so I regasketed the block where it splits, turned out to just be a carb rebuild thing

Gasket maker is absolutely fine, when used properly. I have not seen that method of assembling and then letting it set up before torquing. I am interested to see how well that worked.

Great video

I would have used a gasket myself. I know with the old flathead Briggs, the sump gasket thickness determined the up and down crank play. Briggs had several different thickness gaskets to get the correct endplay. Since those motors (the one you are working on) are known to leak, I would have tried to get a thinner gasket and then apply the gasket maker to it to try and get the same end play as before. But as long as it works, and the person who gets the mower after you is happy, then it really doesn't matter how you do it. Great Video as always and keep up the good work!!

The gasket maker is just fine as long as the crank endplay is good.

Tried using silicone sealant on a Honda GX-390 crankcase cover and the crankshaft wouldn’t turn. Had to put a gasket on it. Thanks for the video sir.

I was working on the same engine the other day, and downloaded the service manual for a different reason. They specify the crank endplay between 0.427/1.298 mm (roughly 1/2mm) That bad gasket looked less than 1mm, so it doesn't seem to me that gasket plays a big role in the crank endplay.

I actually just did this for a customer's pressure washer. It had a Yamaha engine and was going to cost $40 for a new gasket. I also plan on doing this to a Kohler that I can't seem to find a gasket for.

well for me i,d not only use the gasket sealant but also apply when the gasket material part is in place too etc.

Good job Surprised you didn't clean the shaft before withdrawing the sump seal especially after the laborious adapter removal. Further surprised you trusted the seal was not compromised. With the amount of work involved and no exigent factors, I would have used a gasket. Actually, gasket with coating. I've not had any significant problems with the gasket goo but I'm always surprised that it works and feel uneasy that its just bidding its time to let go.

This is beyond my own experience, but I do wish to do this shortly to pull an engine apart, so it was good to see step by step view, I have tried to take of the blade boss but unsuccessful without the proper tools. I’d rather use the gasket unless it was unavailable as many things are these days using a gasket maker would be the only other option which I thought keeping tube in a sealed plastic bag in the fridge may extend its life of the tube.

In a situation ;like this I'd use Permatex#2. It's non-hardening and has done me well in such cases.

No problem using gasket maker fr, i a small engine mechanic and alot of these come out from the factory with gasket maker as a gasket

I'd use the gasket, and recommended sealer

i would have done what you did. good job 👍👌

A paper gasket can only be used on that engine, where as gasket maker is there ready in your workshop and can be used on any engine, saving both money and time.

Those Gasket makers are a mess. The effin tube always breaks on me. That said, sometimes it’s hard to chase down a gasket that fits so I can see the advantage of a Gasket maker. Good tip on letting it set up.

Use some of the old oil on a rag and wipe down the underside of the deck

I had a leak at the base of the oil dipstick tube. Replaced the oring but it still leaks. I think the plastic tube has shrunk over the years so the next fix is going to be gasket sealer around the base of the tube instead of the oring.

Try spray nine degreaser that shits magical

How will I know how much I need to neglect it if I don't have an inspection window in the side of the block?

When I replace gaskets, I use a sharp chisel to scrape the gasket off, and I use rtv silicone, just to make sure that the gasket seals. If you are replacing a head gasket, put a small amount of oil on it, this ensures that if you have to take the head back off, the gasket won't stick to the metal and rip, so you won't have to buy a new gasket.

Hey bro what's up? I saw that you had to get you hands dirty in this video. Even though the sump was real nasty looking a good cleaning made it look almost new again bro.

That rusty deck would drive me insane

I haven’t had very much luck with gasket maker in the past for some reason, so there fore I would of installed a material gasket.

End play will be irrelevant if the oil leak was not fixed and the next owner skips the oil level check, resulting in the inspection window you discussed.

Here in Italy the price of fuel is 4 times more than before 2,2 euros per liter

I would have used both. Light coat gasket maker on both surfaces & the gasket itself in the center..........

A can of rust stop primer and red paint would do a lot of good under the deck

You know why the sump gasket leaks,poor maintance when the air filter gets clogged up the engine has to breath some how,the back pressure of the piston causes this.I tell my customers to check the air filter replace when dirty.btw I charge 60 dollars to replace sump gasket,,,

Probably a home owner that enjoyed mowing wet morning grass.

On some engines, the gasket thickness is important for regulating end play. But since the old gasket was of poor quality from the manufacturer, I think the good seal you created with gasket in a tube will be fine. The old one was so thin, it was not adding end play anyway. It you have a bit more because of your gasket choice, it should be fine. Too little end play is the problem, a little too much is not, IMHO.

cant make this up i just did this repair on a mower that was leaking

yesss siirrrr

I don’t have any problems with using a gasket maker for my own mowers if someone else’s I would use a gasket!

Why not use a gasket?

It's bad advice to say that a cracked block cannot be repaired, especially an aluminum one. Depending on where the crack is, a skilled tig welder can repair it like new. Also, that seal didn't leak before but is much more likely to now after being forced over the rusty shaft. It would have been a whole lot easier to replace it when you had it all apart and on the workbench.

Do you like stihl

Inspection window/ sung connection rod 😭

I do not greatly see anything wrong with your repair, if it works and is low cost might as well, some rust kill on the mower deck maybe, wet grass is ENEMY on steel next to salt water wet grass RUSTS steel!!

I hate Kohler engines so I would’ve found me a Honda or a Briggs motor and put that on there instead

Thats what happens when you use synthetic oil for a long period of time.

The easiest way to remove the blade holder off the crank is to give it a light tap with a hammer

Kohler is Chinese trash "Chonda"..

Tes this mower was in a flood.... Salvage title. OMG !
