crank

Just picked up a 066 without a decompression button and it has the metal flywheel starting to hear some negative views on the saw regarding a weak crank . Should I be worried or be looking for a 066 with the polly flywheel ? just want a reliable saw and don’t need a new 661 . This saw has good...

Hi all at AS. I believe the answer is yes to my question just want confirmation. I have a small oil tank 066 with a poly flywheel.(Crank very rusty). Also a small oil tank 066 with a ally flywheel.(case broken). The poly crank will be wider than the ally crank correct? As someone said before...

Hi all at AS, Will a second gen flat top 066 crank (poly wheel,large taper) fit in an early 066 (ally wheel,small taper )case? Or are they different widths?and no seal to match the large taper/small seal pocket? These are both small case saws but the ally case one has busted av mounts. A quick...

I'm about to do my first top end rebuild. I want to replace the crank bearings and seals too, just to be safe. Will I need any special tools for this? What is the trick for getting them off, and getting the case split?
