Stuck Fox 2.0 Bearing Cap

[ert01]

My brother needs to rebuild some used Fox 2.0 10" travel shocks that he got... the seals are totally shot inside and the valving was wrong for him. Anyways I had some shims and rebuild kits that I wasn't using so we figured we'd use my parts and do his shocks this weekend.

Anyways, the set screws were siezed and we couldn't get them out. We twisted two allen keys and broke a third trying to get them out. Even with penetrating oil and a bit of heat. We didn't want to get em too hot so we used just a touch of heat on it.

Anyways, with nothing working we figured we could maybe drill out a setscrew... That worked, but now when we try to spin the bearing cap off, the whole setup inside the shock body just spins too and the cap doesn't come off.

All 4 shocks have the set screws siezed and we only tried to drill the one shock. Does anyone have any ideas or suggestions on how to get these stupid things apart so we can rebuild them?

call fox, they might be able to give you some advice... I wouldn't go drilling into any more of them.

Yeah I sent them an email... waiting to hear back but I would like to do something with this drilled one since it's at the point of no return.

I thought they're held in with a snap ring, and don't screw off. A phone call to Fox will answer your question.......or you can wait on an e-mail. I don't have patience for e-mails when I'm in the middle of something.

the snap ring is under the bearing cap, which is held in with a set screw, then twisted off to reveal the snap ring.

i know now isnt the time, but people really need to heed fox'es recommendations, wax them motherXXXXers, or they will corrode! next time i will be putting some wax into the set screw hole! thats for sure!

Heat the bearing cap until the set screws break free and come out, you cant really get them "too hot" if you are rebuilding them. Put at least 100 psithe shocks and that should stop the bearing from rotating.

Would 100psi of air work or does it have to be nitrogen?

Don't use air. Air has water in it, which will separate and corrode the inside of your shocks.

Not to mention when air heats up the pressure changes dramatically vs. nitrogen.

sorry I just meant air to stop the bearing from rotating during disassembly, not to run permanently

The moisture will stay behind after the air is gone. Stick with Nitrogen.

Use the air you are rebuilding the shock they will be coming apart and cleaned any ways if you rebuild them right.
