Noooooooooooooooooo, you'll damage it and its way to tight for that

Stick a tommy bar, pointing striaght up, in a vice
Drop Base Valve end of Cartridge onto the above screw driver (through one pair of the hole near the end
Fit 'tool' into the slots where the springs sits - apply a little heat, but not to much as there is a rubber seal in there, to the threaded area and undo with 'tool'

Its tight but it will come undone


Hows this for a "tool" piece of 2x4 and about 15 industrial strength ties. ImageUploadedByThumper Talk1375639319.823158.jpg

congrats - I like improvised tools such as this.

 

 

Still think you'll need the tool to re-assemble the fork, as you won't be able to use that trick.

First time I re-assembled my forks, I didn't use the the 'tool' to hold the cartridge, I just just nipped the base valve up snug - base valve came loose a couple of months later, and leaked oil over the brake disc. Lesson learnt!

doesnt it go together with some locktite? I dont think il have any trouble tightening it up if it held up to all the force I was putting on it to get it apart.

Loctite on the cartridge when putting it back together, not on the base valve when assembling the cartridge to the fork

Yes the RT instructions are a little vague as they cover many models that the fork kit covers

Ive read and been through that and more. I just need to know whats what. Is that small diameter thick (thickest in the kit) supposed to go under the shim stack? In the diagram they supply there is 2 "base plates"




Im also confused about converting the mid valve to a check valve. What needs to be removed and replaced? Is the "new check valve plate" the 2 black shims with the biggest od?

Very sorry for all this but i would love to have my bike together for the weekend.

This is the top shim on the stock mid valve stack. The point is to turn it into a one way valve right? So is this right?

Cup washer
Sleeve
Spring
Single shime
Valve
Rebound stack
Baseplate
Nut

Looks good

The single shim should slide upwards to uncover the ports in the valve, and fully cover the ports in the valve when resting against it.

I used the 3 off  0.11 x 24mm dia shims (that were the 3 largest shims on the mid valve compression stack, for the check plate - a single shim would work just as well

Thanks. What about the "base plate" under the shims on the base valve

I think there was a washer in the RT kit to use as a 'stop', and then you build up the shim stack up on top of it

The RT valve has to go on the right way up - there's a recess in it for the collar which is on opposite side to shims - again check plate should slide up and down

Just an update to let everyone know that the gold valves are WAY better than stock. I may just have to get a shock kit and ask another thousand questions about how to install it  :thumbsup:

thats the conclusion I came to as well

I think they seem to be a bigger improvement, than on other bikes, because of the piss poor std WR fork set-up, which prevents the usual re-shim being done easily (as it can on other bikes which have the proper shim stack set-up, its just a case of adding/removing/altering the shim stack)

 

I've not done the shock, so won't be able to help, but not sure its really needed - you should just be able to by the shims and adjust as necessary

You now have the RT instructions which tell you how stiff the shims are

 

Basically (you cube the material thickness to get the stiffness factor)

 

0.10mm thick = 1

0.15mm thick = 3.3

0.20mm thick = 8
