Hi all,

I've done a search and can't find any info...

Just wondering if anyone has ever rebuilt the damper (not the air sleeve) of a Fox Float rear shock (or similar kind without a piggy-back).

I have taken an old one apart to suss out the inner workings, and essentially work out how to rebuild/bleed the damper.
I have previously done a number of DHX rebuilds, but they are much easier as they have a piggy-back with the scraeder valve on it.

It appears that the damper is pressurised via the hex grub screw near the base of the shock (the centre of which is gooped up with silicone).
I'm guessing that some sort of special fitting is required to be able to pump air (or nitrogen???) into the damper, via this grub screw, and then you would need to turn the grub screw to seal it off before detatching the pump????

If anyone has any experience servicing this sort of damper, i'd like to know how!

BTW, don't bother responding if you are just going to say "take it to a service centre", as I am doing this as an educational exercise, rather than out of a need to use the shock again.

Cheers,
Hugh.

Yes, it's a specific tool for a Nitrogen Charge. Very few places have them because Fox urges you to send it to a tech center. A damper rebuild on most Fox products should be done by a qualified suspension tech.

That's correct, the rear Fox Shocks have Nitrogen in them but that "silicone" plug is not where it is pumped in. I was lucky enough to attebnd a service session with the Fox technician a few years ago. He said thay can tell when someone has tried to do it themselves because they often will pull out that plug but he told us that is not where the nitrogen gets pumped in. I don't know what would happen if you pumped in air instead. Foamy oil?
