taking apart the forks

asmeninis · Post by **asmeninis** » Wed Nov 03, 2004 2:58 am

Hello, Anyone can share own experience of disassembling the forks (FZR1000 1993 USD). Mean need to change the chrome plated tubes. The parts book or service manual won't tell about this. Seems according the Yamaha, it's should be replaced with the lower cast part. There is some stopper bolt like in there. Should I try to screw it out? And then? Thanks, mindaugas

I have no personal experience with this but I have a friend... . I looked into doing the same with my YZF750 forks and was told by a couple of experienced people that it is not practical. One guy told me that he had twisted or bent a set of tubes trying to get the cast caliper bracket/axle carrier off the tube on a set of TLR forks.

It can be done as when I sent mine away for re-chroming they came back with that screw you mentioned having been removed and replaced, but how difficult it was I have no idea.

I would advise against it unless you have the right special usd brace and a set of split seal drivers, oh and a vice with rubber jaws, and then a pan for fluid, and...... The list goes on, I would recomend that unless you are very friendly with front ends, especially usd ones, then bring them to a shop. Most of the cost of the front end repair/ modify (by experienced professional) is pulling the damn tubes. You bring a shop just the fork tubes unassy, and they'll have them back quick and cost effective. Dirt bike shops are the gods of this because almost all dirt bikes have usd. Either way, a good shop will set you right. What do you need done anyway? Chuck D.

Thanks all for replays. Actually I find some support here, locally to finish that exercise. Chuck, the problem is, that down here (Lithuania, if you know such one <img src=http://www.ezboard.com/images/emoticons/smile.gif ALT=":)"> there is no one serious shop, where it can done better, that I can. Cheers

The hardest part is trying to find a way to compress the spring enough to get to the inner nut which allows for the cartridge to be removed/ installed. No dealerships or shops of any sorts? I just can't realisticaly see taking them apart with out the specialty tools. I hate to say it, but in my experience they prove to be a pain even with the tools; without, ? CHUCK D.

Chuck, Actually I made the tools myself: there are pictures in haynes SM and they are simple. just additional hands are needed to compress the springs to take the nut off. I took the cartridge out nicely. btw: it was interesting to compare the internals with the R1's: the fizzer's spring is 8cm! longer, and the rod by 4cm (i wrote this already in another topic). more interesting was to know, that the R1's chrome tubes ARE LONGER by 12?(mm) the FZR's! how it can be?
