AH47 Engine Teardown - Sears Chainsaw Restore

[@b.butcher82]

When I rebuilt my Poulan 47, I couldn't find new crank seals anywhere so I ordered them from Motion Industries. They seem to have any seal size imaginable.

That's a good lead. McMaster Carr is a good source too. www.mcmaster.com/products/shaft-seals/

The manual I have is showing the piston ring end gap .006 to .014 thousands so I would think you are still good for now.

[@dennisharrison4744]

It would run for years like that

7:07 I just rebuilt a 1979 homelite super xl used used cylinder and piston off of a part saw some one attempted to fix it years ago for my neibor they had put the wrong piston rings in it they were for a xl12 they were in the piston I thought they were stuck but they weren't stuck to small ring gap on them was 5/16 gap lol

Dang, that's a huge gap!

Yama bond or honda bont works good for cases

[@jonparkmac]

I had to source each part separately. Mostly from eBay.
