Title: 98 Animal Shock
Post by: Gordo on March 23, 2003, 11:08:37 am

Hello All!

I have a 98 Animal that has a rear shock that is blown and I have continued to ride on it...needless to say that I have no damping. I was wondering how would I go about getting a replacement or if my shock could fixed. It has been a while since i have had damping or oil for that matter.

If any one has a shock they would like to part with that would be great.

 ???if you want to have your shock rebuilt, go to the links here and click on the noleen shock service link. the owner is the founder of noleen and is in so cal. i think they charge $150 and will dial it in for your weight and riding style. it's a cheaper option than buying a risse.

Unless they just increased their price, the rebuild is $100.00 plus shipping.  $150.00 gets you a conversion (such as from a Smart Shock to an NR4).  I had this done for my Animal and am happy so far.  I don't have a lot of miles on it yet, however.  If I had the dollars, I'd probably go for a new shock.

Or you could rebuild it yourself sans the nitrogen.
Not the best performance, but better than riding a pogo stick. And you'd have to change the oil more often.

Once the shock is rebuilt, you can have it recharged with nitrogen at some motorcycle shops.  The nitrogen is charged under a little hex screw on the shock by using a small needle valve inserted into the "self-sealing" rubber seal.

If anyone knows how to do the rest of the rebuild, I'd like to hear from them (i.e. what seals / o-rings are needed?  what tools are needed?  etc.)

Also, we can reopen the debate about the necessity of using pure nitrogen as opposed to using air to pressurize the shock.  I forget what the outcome of that discussion was.

If you get the Risse, you can rebuilt it yourself. ;D

First remove the nitrogen fill screw at the eyelet and use an allen wrench to push in the seal.  This will release the nitrogen charge.
I then pushed in the floating piston at the shaft and popped out the retaining clip on the inside with a push-pin (the most difficult part of the rebuild.  Then you can pull out the shaft.
I didn't obtain any new seals, But I was able to stop the leak on the shaft seal by purchasing an O-ring that will fit in the circumferential valley of the existing seal.  The pressure from this o-ring on the existing seal will force a tighter seal on the shaft.  I don't know how it would hold up under 200 psi of nitrogen though.
When you undo the nut holding the shim stack and pull everything off, you'll see the seal. (don't loose the order in which everything came off).

Thanks for the information.  I actually have a Noleen nitrogen charge needle/guage kit.  When next I need a rebuild/reseal, I'll try this and post again.
