Question - How hard is it to pull three piece cranks and should I even bother? Whole story: Here's the deal. Old mountain bike, but it was a good bike back in the day. (maybe 15 years old - Schwinn MOS Siera... it's a descent bike, really IMO) It's sat for 10 years and the last couple of years have been outside. When I recovered it from Mom and Dad's, orange rust water came out of the head tube when I tilted it to put it in the car. I really want to get it going as I have an itch to do some biking, but very little cash (can't go buy a new bike) I had the front hub done at the bike shop today - the back hub seems okay. I cleaned surface rust off of the chain and sprockets. I've got the brakes working good. The derailleurs seem okay, I bought new shifters as one of the shifters was broke when I parked it and the other was seized from time and the elements. I've taken the handle bars and forks off and cleaned them up along with the bearings and all related pieces and the inside of the tube and I'll grease it and put it back together and it should be okay. The question: Should I do the bottom end - the part that the cranks go through? The cranks turn and it doesn't feel like there is any major problem, (I test rode the bike today after getting the front wheel done and it seemed rideable except for shifting) but there _was_ rust in the head tube and rust in the seat post tube and by shining a flashlight down the seat post tube - there is rust down there. I feel like I should take the cranks off and clean and check the bearings and lube and reasemle, (at that point I'll have it down to the frame, less demounting the derailleurs) but I'm a little afraid I might get in over my head with the cranks because I've never done them. Are they hard to remove or install? Any special tools required? Do you think it's even necessary? Sorry for the long post, any advice is appreciated.
