No clue, but I would be interested in knowing as well.

My 066 leaked awefully on the clutch side. It was a bad bearing that caused the seal to fail.

How does the OP verify that this isn't the cause for his leak?

Not trying to instill anxiety in anyone, but how does he know?

you can understand if the bearing is bad ,but sometimes you can not , the most problem is if you put the seal corectly , he test the saw with vacuum-presure i hope and he find a leak , he put the new seal and now he say that the saw hold ( psi ) so we can say that he solve the problem, if he have again leaks from the same seal then he must see for bearing or something, this is the reason that good technicians dont give the saw imidiatelly after the repair but hold it for a 2 or 3 days in case if something go wrong.

I replace seals with the Stihl puller. Sometimes I replace seals now just to enjoy how well the puller works.

me too ,I set the legs in first by hand then attach the puller body ,then rotate the unit pivoting
on the crank hole to free up the circumference if sealant was applied the draw up the seals
works beautifully. Stihl has purchased the tool company that makes them and the price has dropped considerely
It nowcomes with 7 combinations of legs and manuals specify wich ones to use witheach moddel

Yeah, pretty much.



I use a 2 jaw puller tool.

I am suprised that a puller would work out ok I was afraid to risk it with the poly flywheel

I would not recommend doing that. The correct tool is not that expensive.

Oh not on poly!

Well, the 066 lives! I finally got a chance to actually crank the saw, and it runs great. I have the L & H jets out 1 turn, and it seems to be a pretty good starting setting. I'm not going to fine tune any until I pick up a 32" bar, but right now the saw is running about as well as I could ask. Idle is good, throttle response is great, and I can flip it to side to side without any RPM change.

Thanks for all the help!!
