Hi, I'm stuck on my NR-4 now, I thought it would be a good time to service it after doing my rear brake. I can't figure out how to remove the piston, I've dismantled the piggyback oil reservior and removed some pretty nasty oil. But what now? Has anyone ever done this before?
I've downloaded the NR-2 service sheet from the files section but it's only got me this far.
Any pointers would be great Cheers, Luke
PS- yes I know this was a silly thing to do, but sometimes my tool arm is quicker than my brain [smiley=disbelief.gif]

oh dear. the shock is nitrogen charged so unless you have the noleen equipment - then you're going to have to send the parts to a noleen service agent to fix it up.
Also, please be careful because the damping pin is held under pressure. There is a good story where a proflex sponsored UK rider shot a damping pi through the car roof in the carpark at a race.
the only noleen servicers i know of are CVI in the UK and NoleenUSA

I have a noleen filler kit, and I was carefull to bleed off all the pressure in the dampener before dismantling it. I also have a complete new set of o rings and seals to install. All I need to do is figure out how to remove the piston to put them on. Then I can reassemble and recharge the shock with the filler kit.
But the piston is prooving very hard to remove- what am I missing ::)???

;D wahooo! I have the piston out and disassembled. I looked up a page on how to service motorcross shocks, and everything on the NR-4 is sooooo similar just a lot smaller. I'll write a little how to on this when I get a minute.
But now for the bad news....... my seal and bushing kit is the for the wrong shock!!!!! It's a noleen nb-1000 kit, which looks like it may be for an older noleen shock with an 8mm shaft. I might just have to source some new o-rings and leave the bushes be. [smiley=upset.gif] Oh well, the kit probably fits the shock on my 955 in NZ anyway ::)

Do you have any pictures of the NR-4 disassembled. I bought the nitrogen filler with the intention to do the same thing but without proper instruction I am too intimidated to start. Is this the filler you have?
