Trying to save an old 015 AV

[If_it_aint_broke]

Not a professional by any means. I just acquired an old 015 AV, and I'm in the process of rebuilding it. I'm used to 4 stroke engines, and have built a few. I have pretty good mechanical ability, and do all my own automotive work (and sell parts for a living). I thought I could just wing it with this rebuild, but that was a bad idea. I'm good with small engines, but 2 strokes are put together so differently that I made some serious mistakes. Broke the clutch because I didn't realize it was left hand thread (real idiot move there), thought it was just peened on and needed some "extra persuasion". And, when I split the crankcase, for some reason I expected to find a normal (for 4 strokes, anyway) rod bearing arrangement. To my surprise, I was met with a one-piece rod, and a bunch of little rollers. Moved it just a little bit and they all fell out...right into the dirt. I just found (finally), the service manual. Rest of my parts should be here today.

I'm also pretty new to using a chainsaw in general. My first experience was because of Helene. We got hit hard, and I mean HARD. Not as bad as NC, but we lost power (and water) for almost 3 weeks.

The 009-0015 are a strange bird, but not terrible saws.

As all saws left hand thread clutch. What did you break?

Rod bearings lower , are individual and the rod holds them in.

The nut part of the clutch collapsed. I should have known that but in the automotive world we rarely see left hand thread, so it just didn't occur to me. I thought it may have been a prevailing torque nut, and did not notice that it was part of the clutch itself, and not a separate nut.

I have 009's, 011's etc,---VERY hard to work on. Ran into a 251-c that I never did get the clutch nut off of! They tend to round off and then no way to ever get a bite on them. not sure if heat would work or not on these. 251-c is laying under the bench in the junkpile right now!! Probably go in the trash can later!

Holy Moly! I never new these saws were hard to work. And I've worked on hundreds. Must be my state of mind (or lack there of).

I good fellow on the other site was nice enough to send me a box NOS spare parts for my 009. Was lucky it included a complete oil pump assy.

Mine has been pretty reliable. Only problem was the self tapping screws in the muffler stripped out. I tapped the holes for allen head cap screws.
