This Will Destroy Your 2 Stroke Engine EVERY TIME!

You know as a disabled vet I've been going through different Stihl certifications to work on warranty work. I've learned so much from this channel I wanted to thank you for your time you put into these. I could probably ask you 100 questions regarding chain saws and weed eaters. My problem is I get to frustrated to easily, I like perfection the 1st time around but learned really quick that's not how it goes. Again thank you.

When I worked on specialized equipment, we used green Loctite 609 on the outer race of bearings. It held the bearing in place and acted as a seal as well. These were larger shaft bearings. One good thing about 609 is it's anerobic and it cures fairly quickly.

Greetings from the other side of the world, rural Arkansas to be exact. Wonderful video on perhaps the most neglected aspect of two stroke engines. In fact, this problem was my introduction to chainsaw repair and the start of a great hobby. It's rewarding to see someone else using Dirko on the outer edge instead of grease, as most do. Dirko acts as a lubricant when wet and forms a seal much better than grease when dry. One thing I might add: a twisted tube of thin, flexible plastic, such as the sturdy plastic bags that dog food or cat litter come in, can also be used to get the seal over ledges safely, and it's a universal fit. Thanks, Tom!

Excellent tip for future reference! While I’m not rebuilding a chainsaw, I’ll be rebuilding the engine on my 1978 LawnBoy 5277. Pretty much the same deal though with it being a 2 stroke. But if I ever need to reseal the engines on my chainsaw, trimmers, or blower, I’ll definitely keep this tip filed away in the back of my mind.

Great tip. Most people don't even know how to pressure and vacuum test, or that it is even needed. Merry Christmas!

Thanks, I learn as much a I can from videos like yours about maintaining my equipment. I haven’t run into anyone talking about this preventive maintenance, so thanks. It should save many small engines from an early failure! Good job, mate! From the US.

no wonder your subscribers are going up Tom, putting out good tips like this one 👌👍

The best oil seal insertion tool for me has always been a piece of xray film, used similar to the can but 100% safer. Plus you can inset it over the step to the bearing so that the seal moves in smoothly

Well done Tom and love the installation tips and manufacturing your own installation tools buddy.

Love it. It's tips like these that makes the difference between a good tradesman and a great tradesman.

It is hard, ..... to not like your videos when they are so informing. I hate watching them because I don't necessarily want to become a small engine repairman! :.))) Thanks, and have a pleasant 2024.

One could also 3D print a seal install tool, so long as they sufficiently sand/polish the OD. Layer lines wouldn't play nicely with the seal. Resin printing would make a very smooth install tool, but most of us don't have resin printers.

Great info Tom, never used the caulk tip trick but will now 👍

Wow. An excellent video that wasn't "ethanol scaremongering". Thumbs up!

I'm getting ready to replace the seals on a LawnBoy mower...what a great tip! Thanks! Subbed

Using grease in the cavity of the gator spring will keep the spring in place upon impact with a seal driver , used them every time when replacing crank,cam, and heavy truck wheel seals, never a problem after 45 years ,roger cheers from Canada

Deserves a million likes. Great video.

I enjoy making my own tools. Thanks Tom

That’s a great tip. I was thinking of using a socket . I do residential siding so I have lots of silicone sitting around
