Chainsaw Repair

I have seen wear on the seal area of the crank like that before.  Have been able to work around it by seating the seal a bit deeper (check to see that there's room for the seal lip first).

Husky flywheels (at least on 100/200 series, 285/1100/2100/298/2101) always seem to be a **** to remove.  I always have to use a puller on them.  Most others (except old large frame Macs) seem to be more cooperative.  May have something to do with the tapers they use.  Just a SWAG...

So far I have always used OEM seals and o-rings on these.  I usually replace the little oil pump discharge x-ring as already mentioned.  When that leaks, oil dribbles out from under the pump rather than going where it is supposed to.

I set seal deeper and all good.  Between the marks on crankcase area and the crank wear seal area. Seems I got by both.

What is this x-ring? Is it the small o-ring where it goes into the bar oil tank?
