Fork Seal Leaking
Posted August 12, 2009 - 05:36 PM
I'm sure the forks don't have equal amounts of oil after losing some. Can you add fork oil without removing the forks, if so how? Also if the seal is shot and I end up having to replace it, would this be a good time to go ahead and install some gold valves, or would that be a lot of extra work? I just felt if I had to tear everything down to do some seals, might as well throw some good valves in there while I'm at it.
Thanks a lot!

Seals are quite easy, just need a seal driver.
Doing gold valves is quite a bit more in depth.
I change my fork oil 3 times a year but have only done one complete teardown/ rebuild.

It's all in your manual but basically
Use an impact to remove fork caps.
Use impact and open wrench to remove springs
Drain oil in outer chamber
Remove dust seal and circlip
Hammer slide tubes apart
You can now change seals and bushings if needed
Use the spring for friction inside lower fork tube and an impact gun to remove base valve
Remove inner chamber and drain
Make sure you use a plastic bag over the fork tube when installing new seals

The other steps I mentioned only take minutes. All the time is spent bleeding the forks.
Make sure you measure fork oil level with springs out, fully compressed.

Hey thanks for the info. That seems like a lot of stuff to take apart, thats what I wondered if it wouldn't be a good time to throw valves in there too.
To just to the fork seals is a simple job. You could have been done already.
Look at the RockyMountainATV video on youtube and get to it!

I cant watch them here at work but if they are the rockymountainatv videos on open bath single chamber forks, then they are perfect
