Stihl 200T- OEM or aftermarket crank seals and bearings

[cookies]

They are 100% notorious for the intake boot ripping when a av mount fails, only use a oem intake boot!

No up and down play, so don't think it needs bearings. I haven't bought crank bearings or seals yet since I may not need them. Taking my time with this build. I did buy the tool for seal installation just in case. One side of that tool fits the clutch side and the other side fits the flywheel side and looks like it has good surface contact for the whole face of the seal. Sound like you recommend the OEM seals over aftermarket. I was just going to leave the woodruff key out until I put the flywheel back on. Lots of opinions on aftermarket seals, but going OEM on any bearings and seals, but did replace the fuel tank with an aftermarket one. Appreciate the advice!! Thanks

Gasket kit with seals ,cost less than seals from Stihl.

Did all that, still screwed it up. Couldn't get it out with the seal puller...had to disassemble the case...again...

Not a real big deal to split the case, though.

True, just annoying

It's the best way, it reduces any chance of scoring the cases where you pull or pry the seals out! As far as I am concerned, its the only way I will do them. Then it can be all cleaned and a new gasket installed . Best method I have found.

You don't need to heat or freeze, just line everything up perfect and drive them squarely and carefully in. The seal tool is a good tool, use it, does it have the bullet shaped piece that goes over the end to keep the seals from tearing on the flywheel key? Are you sure it needs bearings, is there up and downplay on the crank ends or just side to side play? And I hope you didn't buy China knock off bearings ! Used OEM are better than China crap.

As long as I am asking dumb questions, do you use any sealant on the cylinder gasket? Not wanting to increase compression or check squish, just looking to have best seal.

If a jobs worth doing, it's worth doing proper

Grease is perfect for a factory gasket, both sides. Dumb people I know don't ask many questions.

What do you find annoying about it in particular? How long would you say it takes to pull the seals without the case split ?

I have references( used to be friends) that will swear that I am dumb!!

Thanks for the advice!!

The last time I tried I couldn't get one out with the puller so gave up and split the case. Now I don't bother trying, just split it

Finished product with new OEM cylinder and piston. Vacuum and pressure test with no leaks. Couple of other new parts plus bar and chain. Started right up and sound great. Will try it in some wood this week.

020 crank seals are rubber and the same size

Well is it done yet?

OOOPS!! Forgot to update and yes, it has been done for a while. Finally got it out to use if a few weeks ago and realized the carb was needing repaired/replaced. New carb (aftermarket) installed, but have not tried it out yet. I do plan to rebuild the OEM carb. The guy that gave it to me keeps hinting that he sure would like to have it back. He knows that it was a fair trade for the work I had been doing, but likes to mess with me a little!
