Update
Tuesday, I got most of the bike taken apart.
Pretty much everything but the BB. :x
As Osella says above, the components are pretty much the same as a '97 Y33. The Manitou Mars C fork is newer (2000?), but the components are almost all XT, but the V brakes are XTR. Unfortunately, the right rear came apart when I took it off of the bike. So I'll probably look for some XT ones to replace and keep a consistent group. Cranks were in real nice shape, though the sachs chain is a little rusty and the cassette is a cheaper Shimano one (no aluminum spiders) so both will be replaced.
The rear derailleur is in good shape, but needs a new lower jockey wheel. Bushing was rusty, and somehow the end was deformed (flared). Never seen that before...
While cleaning up the front derailleur, I heard something small fall in the sink. I figured that it was the cable clamp bolt, but it was 1/2 of the cast aluminum part of one of the pivots! So I need a new front derailleur... :roll:
Wed eve I got the BB out; it was a MF!!! :x Probably torqued way too tight as there was a huge amount of red grease on the threads that was pushed into the BB shell. BB feels like new.
A LBS may have a set of main pivot and swingarm bushings in their old parts pile; we'll see next week.
They're no longer available through Trek.
I cleaned the frame and swingarm with a water based degreaser, and they cleaned up better than I expected. So I need to figure out how much (if any) touchup to do.
When I bought the bike, the fork was a mess. It held air, but had no rebound damping. The right rubber boot was slid up on the stanchion, and held there by the seal which had been removed from the lowers (see 2nd photo on my original post). And there was a bunch of dirty, thick, black grease smeared around inside. :cry:
Tonight I tore apart the Manitou Mars C fork. It cleaned up really well! I can't see anything wrong with it at all. There is a little bit of discoloration on the right (formerly greasy) stanchion, but nothing looks like a problem. The elastomer was petrified, but I found 2 small urethane ones in the spares box that fit. I guess that I need to buy some 5wt fork oil and see how it goes!
More pics in a day or two...
