Getting my dampers ready to send off for a refurbish. Nitron state on their forms that they must be clean and springs removed. I'm getting new springs put on whilst they are there anyway so it would make sense to remove them and save weight/postage cost.

 

I don't know if I am being stupid but I cannot see how they come off. The collar at the top is up as far as it goes and doesn't screw off and the collar at the bottom...well thats just there!

Never removed my springs before they went

There should be a steel snap-ring in a groove where the bottom mount sits. Probably under the dirt and grime

 

Take that out and now the bottom mount can slide over the alu base and it frees the spring which can then be removed.

 

Bye, Arno.

No - never remember doing that last time for me either. I think I might not bother.

As Arno says, you just remove the retaining ring which will allow the bottom collar to slide off. It's really very easy and worth doing even if it's just to keep the weight down for postage

 

You can see the slot where the ring clips into in this picture

 

 

By the way, it's worth getting the spings powder coated while they're off. Mine came up an absolute treat, definitely better than the factory job.

I've also got some Nitrons, may I ask how many Miles they should be serviced at and at what cost?

Depends of use/mileage/type of use I guess, but probably every 3 years. Basic service is £65 + VAT (per shock) but I have heard that it may be going up soon...by quite a bit!

Thanks...managed to remove 2 of them but the other two I cannot slacken the spring - too tight so I'll leave that to Nitron.

Mine are 2 years old with 30k, do you know what they do in the service? Apparently there is a service kit available for DIY.

Correct size drill bit (8mm?) in the lower collar will work (and turn the spring with your other hand at the same time).  Good wire brushing of the thread first and some easing oil.

 

Those snap rings are tight aren't they?  Tried with my nails once - ouch!

Thats just the o-rings for the bearings IIRC.

 

As has been said, spring cup off and remove the snap ring.  A small screwdriver is invaluable for this!  I stripped mine, cleaned them with parts cleaner and ACF50'd them before sending them off.  The service Nitron do is all the guts (not DIY-able).  Mine came back absolutely superb. 

 

One thing to bear in mind is that if you're going for the extra droop mod then you may need helpers. Aimy had a thread somewhere about this.  I cant recall what the conclusion was.
