04 wr450f - linkage bearing questions
Posted January 03, 2012 - 10:49 PM
Got my bike pulled down for some annual DIY maintainance, currently attending to the rear shock / swingarm linkage bearings. I have never had the linkage apart since ive owned the bike.
What is the browny coloured material around the needle rollers? It has a sort of rubbery consistency, but im not sure if its factory or just grease residue. I had to "tear" it to get the rollers out, they were all seized.
Can i just clean everything up and re-pack the needles back into the bearing race with grease without the "rubbery" surround?

Best bet is replace, especially seeing how many years it's been it won't be a big expense. Myself I can find them this way within a month and I go through about one set of bearings, and a few lower shock ones a year, so if they are possible to be saved I will.

I did have to replace the swingarm pivot bearings as they had real pits in them, I used a kit from Pivot Works, nice kit, felt like good quality, complete and fit perfectly.

Cheers for the responses and advice. The bearing above cleaned up pretty well actually and i was happy to reuse it i wire wheeled all neddle rollers and the spool and cleaned up the race by hand. The other bearings in the linkage were mint condiion. No pitting, rust or staining at all, no slop with spool piece. All bearings repacked wih belray waterproof.
Attacking the swingarm bearings tommorow after a relaxing weekend at the beach;)
Question - the thrust bearings in the swingarm, are these accessible and do the need checking and refirb?

Amazing longevity for linkage bearings! I usually have to replace mine every year but my bike sees a lot of water. I use waterproof grease but it's not enough to stop the rust.
Wow! Once a season? How much do you get to ride and what do you ride through? It would be worth for you to come up with a grease fitting setup for your link.
