Pace RC35 MD damper info needed

[jimo746]

Anyone have info on the damper unit in the RC35 MD fork?

Mine isn't leaking, but it needs new oil (after I emptied it out whilst servicing :roll.
So oil weight and quantity /level info needed.

Funnily enough, as I was clearing some stuff from my workshop, I found a very old bottle of RST fork oil that I used in my RC35 MXCD forks. It’s 2.5W.
I’ve got the manual somewhere so I’ll get the volume.

50ml it says, with a squeegee bottle though and a fine tip, if you don't already have the Pace bottle.

That's fine, no thanks necessary.

THANK YOU!!

I must have missed your previous reply, and the thread was lost amongst all the other threads. Next time I'll turn on notifications

I've replaced the elastomers with RC36 springs, so a working damper would be very useful!

Ah, I did that. Springs made by Eibach IIRC. They weren’t a perfect fit though and I had to machine out a nadge from the upper leg seats.

Re:

Good to see[hear of?] a spring conversion, I have been doing those for a while, best to fit a spacer narrower than the spring so the assembly still fits in the dropouts correctly without the springs binding/clashing with the inner dropout section inside the carbon. And ease the tops as mentioned.

Dont go above 5WT oil as anything thicker will just blow the reed valve on the underside of the piston. Fill the damper to the brim with the control valve still fitted[fill through the screw hole], pumping the damper to expel any air and finally end with the damper rod compressed so there is allowance inside the cart for the volume of the damper rod.

It would be a good idea to strip the damper & replace all the seals/quad rings[I have new seal kits at £8] as they will have age hardened and will leak. Check the damper rod for deep scoring too as that will just eat up the new seal. Can check the reed valves too.

Hope that helps
Cheers
