Title: noleen nr2
Post by: simonlovell99 on April 06, 2011, 08:21:58 am

I got a noleen nr2 shock, I need to re-pressurise the shock with 130 psi. Where can I get a adapter to fit my shock, in order to pump it up.

I am based in the UK

Thanks

An NR2?  I may be wrong, but I don't think you can just pump them up, aren't they pressurized with nitrogen when they're made/serviced?   
I enquired about servicing an NR2 before and apparently it's not really "home servicable", it is rebuildable though so a decent shock/suspension tuner should be able to do that, seals and parts are even available from the NoleenJ6 website.

Have you had the shock rebuilt already?

I'm not sure where the pressure lives inside the shock, and don't think it's an easy job to do at home (who keeps nitrogen handy?). I had mine serviced at an Ohlins motorcycle shock service centre with original Noleen parts. I'm guessing the Noleen shock is similar to the Ohlins shocks, plus they were recommended to me by Noleen as the guys with the gear to rebuild and 're-nitrogen' it.

It cost me about 30 quid excluding parts (I think they were about 20-30 quid).

ah ok. i read/heard that you can put oxygen in the shock and that you need between 120 - 170psi. As my shock doesnt rebound (unless you pull it!)

iirc if you take out the small cross head screw at the top of the shock then the air charge is put in there.

please don't blame me if you try this at home and up with an NR2 shaped hole through your head  ;D

You can just type in Noleen on ebay and find the charge valve kit.  Then you need to find a shop with a bottle of nitrogen to charge the shock.  Or if you can find a fiberglass shop that uses an old Venus chopper gun, you can adapt the charging pump to do the trick wtih your own little bottle of nitrogen.  They are so old that they might just let the pump go cheap.

ok, I cant find anything on ebay. on the sevice instructions I read on here and other sites, it says npormal air can be used instead of nitrogen. If i cant find the part then the shock is useless.

Normal air is 4/5 nitrogen anyways but with additional gases and water vapour.

Reason a single inert gas is used is that is is more controlable and no moisture.  (goole flling tyres with nitorgen).

filling with dry air (do it on a ot and sunny day) should work and tbh you problably won't notice the dfference; it'll be an improvement on what you have already.... the shock is problaby knackeered anyways so what have you to loose?

where could i find a adapter to screw into a shock pump and into the shock to put in the air.

Filler kit for the Noleen shock.  http://cgi.ebay.com/NOLEEN-BICYLE-SUSPENSION-GAUGE-FILLER-KIT-/380329984983?pt=Cycling_Parts_Accessories&hash=item588d6f03d7

I've considered using some of my inert MIG welding gas to charge my old shocks.
