I referred to the IPB as a guide. As I removed parts, I cleaned and inspected them. I removed the right side housing, then the outside chain guide, then the chain and the bar. Next, I removed the adjusting pin assembly, the inside chain guide, the sprocket drum, and the bearing assy.
After ensuring the saw was clean, I reassembled it in reverse order of disassembly.
Once assembled, I followed the adjustment procedure in the owner's manual for the chain/bar assy.
Pretty straightforward remove/replace and adjust procedure.
Saw worked super on trial cut of a 6" thick log.

Look. There was nothing to replacing a missing part. The whole point of this review? That I have fixed just about all of my old equipment using out of date, No longer serviced, parts that I would have been spending alot of time looking for it hadn't been for Ereplacmentparts.com ! They have the parts, the know-how, and the customer service, that will keep me coming back! Thank you, Midvale!
