Any tips on separating this crankcase. It took me a while to get this far because I didn't want to damage it and now I'm on the last step and don't know what to do. The case is small and odd and I can't just clamp it and hammer it. My puller doesn't seem to fit and I don't have welding tools to build a separator.  I have removed the coil since taking the pic. nothing left but the two sides and the crank.

no reason. just for recreation and cleaning.  I have every component off and washed and refurbished and don't want to put them back on a crusty case.

If you're bond and determined to split it the thing most likely comes apart like most Stihls .You'll need to heat the bearing pockets with a heat gun and probabley a light tap with a dead blow hammer will shake it loose .

Just tap now not like driving a railroad spike .To put it back together freeze the crank,bearings and all .Then heat one side of the crankcase halves and install then the other side .

Now this is assuming the saw is built like most with shrink fit on the crank .If it's slip fit it will come right apart or should .I can't really say because I've never split this model althouh I have changed seals .

The IPL shows a retaining ring on the clutch side bearing so it could be a slip fit .

Got to use it yesterday in between rain drops this little saw can cut

One problem I found I need new clutch spring chain starts to spin at idle (2650) I know they don't make them any more but the cost of a aftermarket clutch is a little high

I don't see any retaining ring on this one but maybe I'm wrong. looks like a small bearing on the flywheel side and a big one the other side.

You wouldn't see it  because according to the drawings it's on the inside .Also according to the drawing it appears to be a flanged bearing on the clutch side .

So then if I'm correct it has to be a slip fit on the crankshaft because if it were a shrink fit you'd never be able to pull the crankshaft with a spring clip retainer on the inside .

So pull the case bolts and see what happens .There should be 6 of them ,M5 by 18 slotted pan head .

On those clutch springs you might give Scott a ring because he has tons of stuff he doesn't even have listed on his website . Between him ,Sawagain and good ole Bryce in Washington state you ought to be able to locate them I'd think .
