Hey, guys, long time. Missed you guys and the discussion here.
I was recently given some garage-queens and I'm getting real close to getting them back in the woods. They had out-of-state shop tags on them, so I suppose they were buy-outs of a defunct shop. What I got:
Stihl 017; needed clutch assy, bar and chain, oil pump drive, sprocket cover and bar adjuster. Got a package lot of all the (used) stuff - less what I already had hanging on a nail and the bar adjuster - I needed for cheap. It's all together except the bar adjuster, that's going on this weekend. Handy little 14" limber. Starts, runs, idles fine. Found out why it was shelved before being scavenged for parts - the muffler screen was 100% plugged - about 1/6" of rusty scaley barnacles totally blocked it. No wonder it was retired.
Stihl 036 Not sure if it's "pro" or not: Needed both orange plastic covers, sprocket bearing, bar nuts, sprocket cover, air filter, muffler cover, bar and chain. I already had a 20" B/C on the nail for the MS460, it went to the 036. I got it all assembled then the fuel line cracked. Good timing, I suppose. I hope to get a new line this weekend. The piston has minor scratching on exhaust side, intake side of bore looks 100%. It did start, run and idle before the fuel line let go. I'm pretty optimistic about this machine, but it may well bring on an early retirement for the MS290...
now the actual subject of this post...
Stihl 024 This was the cream puff. It should be a great step between my MS170 (already had that, the 017 listed above is a duplicate and has already been forwarded to my "cuttin' buddy") and MS290/036. Needed new sprocket (chain was obviously run quite loose based on wear pattern), bar and chain. And a good douching.
My issue is thus:
Got the stuff, and I'm having a bear of a time with the clutch-end reassembly. The circlip and steel washer are super tough to get on, and the stack-up is so tight that the sprocket does not free-wheel relative to the crankshaft. It appears as though the oil pump is friction-driven by the back-side of the clutch, thus always driven, even at idle. It appears as though the clutch is not travelling deep enough inward to allow the sprocket adequate clearance versus the clutch hub. I disassembled the whole ting down to and including the oil pump - no foreign stuff skewing the stack-up, no extra stuff in there, all looks as it should. Re-assembled, same deal.
I've looked over the IPL, it appears as though I have it all together right, but I'm sure I dont. I've run a search here for "024 +oil +pump" and came up empty. I hope someone here has dealt with this issue and now consider me a nutcase, and I have no defense for that thought. Enlightenment, gentlemen?
Thanks in advance.
Oh, for the record, all my new and used parts came from my gem of a dealer. Once he understood that I was doing this for me, not one of his (potential) customers or for profit in general, he offered to scrounge through HIS parts saws and bag up me up what I needed. He's cool like that.
