'99 Linkage and Swingarm Bearing Replacement
Posted March 25, 2003 - 11:31 AM
Has anyone done this yet and was it a big pain in the butt? I can't believe the lame setup that Yamaha used on the linkage and swingarm bearings.
Now I admit that I do not grease up the bearings more than once a year, usually before the season. So it came as no suprise to me that I had a couple bearings that were rusted. What did come as a suprise was that they don't want to come out.
First it took longer than it should have to remove the seals. Then those stupid pins kept falling out. So there is really nothing to keep the edges of the bearing case from collapsing on itself instead of just sliding out. I am using a 22mm socket and a hammer to drive them out but some are not budging. Only one has come out of the arm relay. The others are stuck in the arm relay and connecting rod.
At first it was only going to cost me $150 for new swing arm and linkage bearings. But now it is looking more like $350 for a new arm relay and connecting rod. Possibly up to $1000 if I need a new swing arm too.
Anyone have suggestions on what you did or what I can try.

Welcome back to ThumperTalk! I have been wondering what happened to you. How has life been treating you? How is the Wife and baby (now a toddler!)?
The easiest thing is to use a bearing press. I too have been forced to work w/ seized bearings. You can try heating the area around the bearing w/ a torch to get it to expand.
I used an approach my buddy did a long time ago on his '66 Mustang working w/ brake calipers. He heated the area around the piston. When he had sufficiently heated it up, he put ice on the piston. The rapid temperature change, along w/ whatever arm grease, did the job.
You might try a bench vise if it is heavy enough. Make sure you use the right size sockets to push out the bearings. Be sure and support your shock links so as not to twist them.
A machine shop or an automotive shop should(?) have a bearing press. I really hate paying anyone to work on my bike, but if you don't have what you need, and someone else does...
I hope you get them out Dougie!!

I'm going to start with my neighbors. Two that drive those big utility trucks with lots of tools. If they can't help, it is off to machine shop.
Yep, it has been a while since I've lurked on TTalk. But bike season is approaching and I have started getting it ready for Moab. But I must say, the toddler is a big time consumer (in a great way). She is doing great and getting bigger everyday. Thanks for asking Kevin. Doug

Last night here at work I installed a Pivot Works bearing kit for my buddy's 2K YZF426.
The bike has been neglected, and I really needed the hydraulic bearing press. One of the bearings took 3000# pressure to get it out!!
There is NO WAY that thing would have come out without the hydraulic press.
Hope you are in better postion than I was!

I just finished this on my 99. I used a socket and DEAD BLOW hammer. If you don't have one (dead blow hammer), invest in one. And for the seals, I used a bench vise as a press, for the seals.
Good to see some TT "old timers"

If you rebuild the shock pivots remember that there is a clip in there that holds the bearing in. The bearing only can be pressed out of the side with the clip.
