rear shock

[xr-jorger]

how hard is it to rebuild a rear shock, I found my shock leaking this morning. ?

I think that's something you want to send out. Do a search I know others on hear have found places that are good at it. They say you have to be real carefull how you package it for shipping.

The procedure is in the service manual if you wanna give it a shot.

[Thumpmeister]

The service manual does do a good job, but I think you might need some special tools...

Like it was said; your better off sending it off and having it professionally done.

Do it yourself. I just did my first one. I did not have a service manual but found everthing I needed online. I oredered my parts from RaceTech. I changed the shim stack in both compression and rebound as well has going to a heavier spring. Now I could do it again in a couple of hours. Cleanliness is next to godliness.

My shock is leaking and I want to try to rebuild it myself. Could you point me in the right direction of finding the procedure/manual for the shock. I have a '91 xr600r and i'm sure its the original shock. I read somewhere that if there is oil leaking down the shaft of the shock that means the bladder has burst, is this true? Could you also tell me which parts I should replace.

thanks

At the bottom of the last it shows the seal out of the seal head. The dust seal is on the top of the seal head and has to be pried off.

Yes, no nitrogen in the bladder will ruin the bladder (you would need a new one) and make the seals go bad quick.

the seals dont go bad, they just cant work as they are intended. Rod seals need pressure to seal...no pressure no seal and thats why a good design has a back up seal that does not require pressure just incase something happens, like a schrader failure.

Well I discovered that if I press the schrader valve and open her up real fast there is still presure, but oil sprays out also. What does this mean? Thanks for all the links and help, I found a shop that said they would rebuild it for ~$100, I think it will be worth it for me, I wouldnt know where to begin finding 150psi of nitrogen.

[BWB63]

Actually without the needed pressure they roll back and forth on the shaft making them wear much faster. I was not talking about that the lack of pressure is what makes them leak, that is true. Seals do go bad for different reasons. A nick on the rod, dirt (inside and out side of the shock), age, wear. Lack of pressure will make the bladder fail fast. As does installing it wrong. the bladder must not be installed with dimples. If it is it will wear only at three point making very small holes leaking the nitrogen into the oil. Most shops fill the nitrogen for about $20.

XR-jorger,

The shock is very easy to rebuild. Where in CA are you? I live in West Hills, near the LA area. I have nitrogen and if you come by with the parts/oil I can show you how to rebuild it in about an hour. Shoot me a PM if you are interested and I will get back to you sometime tomorrow evening.
