024 AVS tear down
« on: July 28, 2012, 11:51:20 pm »
Hi all, been reading a while here but this is my first post. I have recently bought an 024 that has had a bit of a hard life. I got it running with a carb kit but it kept on loosing it's tuning, so since the piston is worn I decided to pull it to bits and replace whatever it needs. My first question is should the crank be stiff to turn over by hand? I thought the crank seals might need renewing but they look visually ok. There is no play in the bearings. My next question is should I just replace these anyway now I'm this far in, and is aftermarket ok?

Welcome to the site.

Being as you have it torn down this far, I would go ahead and put seals in it.

Some after market seals are OK.

I'm sure after market seals would work except for the fact most Sthl seals are OEM meaning special design and they own world wide rights to them .

For example the clutch side seal part number 9640-003-1600 is 15 x 29.6 x 4 .Now that 29.6 MM OD is the snag because it's an odd ball size .

Conversely it appears the flywheel side .
,part number 9640-003-1190 might be standard being 12 x 20 x 5.

That is the correct number because I've got two OEM seals right in front of me as I type this for one of my 200Ts. Those were like 8 bucks a pop from a dealer .

Both of you are correct, the 9640 003 1190  12 X 20 X 5 is used on both sides of the 200T

But the seals are different from one side to the other on the 024 and the other seal is the 9640 003 1600 for the clutch side of the 024

For that matter so did I .However until this thread I had no idea the small seals used on the 200T also fit other models .Nor did I know the special seals used on the flywheel side were being produced in after market .Nice to know for future reference .Glad this topic came up .

Now if somebody would just throw together a quality after market piston and cylinder for the 020/200Ts it would be a red letter day . :)
