Here's my Showa in bits when it was at a specialist for rebuilding........recharging done after removing the reservoir cap IIRC.
From memory, Sachs can't be rebuilt and Showa etc can. Think the cheapest Maxton can't be either but that may be nitron I'm thinking of.
I'm sure you know what you are doing, but remember this things can be under high pressure when taking them off.
IIRC the cover is just a cover held in place with a wire circlip - no pressure. Once the cover is off and the valve cap is removed, the nitrogen is pumped in or released via the valve, which I think is similar to a tyre valve. Sorry, can't tell you what the pressure should be, although 100 psi rings a bell - don't take my word for it, though.
Thanks Arquebus. I'm not sure the Nitrogen I've (sort of) got access to is at 100 psi, will have to have a look. Nasher
It might have been 150 psi - I just can't remember. I have tried phoning the guy that did mine without success, so maybe a phone call to a friendly Main Dealer might help. However given that repairing a rear shock isn't as easy as it might seem; and of course if you find the reservoir seal leaks once you have done it and paid for the parts and a recharge, its a bugger if you have to do it all again. Bearing in mind the cost of the parts needed etc, maybe it is worth using a specialist such as: Ducati 900SS Shock Absorber Rebuild & Repair Service
So Ghost Rider, are you saying you've seen broken swingarm lugs as a result of someone fitting a Sachs Suck to an Alloy Swingarm? Please confirm that, and yes, would really appreciate seeing those photos. Not least because I know someone who has a Sachs Shock in an Alloy Swingarm.
