Graham I stole this from another forum.
Hello David and all,
I have a R26 and have resotered all 4 shocks.
The top is a threaded "plug" that acts as the top and gasket holder all in one, once you unscrew the top you can pull out all the insides, wash and inspect them. You will find one conical spring above the piston and one cyclindrical spring below it. At the bottom end of the inside tube you will find a valve with a conical spring on top and a cylindrical spring below. All conical springs are identical. Two sizes of cylindrical springs. I had to have all of these springs made for me, I could not find them at any shop. I also had the main springs made for the front shocks. The sealing "O" rings and top gasket I bought at a industrial gasket shop (common off the shelf items). One of the pistons was cracked, I had a new one made by a machinist (lathe operator). I purchased shock absorber liquid, filled them and closed them. The 4 shock absorbers work perfectly. Please not that the bike will not be raced nor driven wildly cross-country, it will be looked after. I live in Argentina and tu purchase any spares or new parts out of the country is usually prohibitivly expensive (as was the case of new shocks or cartriges), we earn low salaries and also a disvantageous exchange rate. so in Argentina it is relatively easy to find someone that can make spare parts at a very reasanable price. Make sure you put new rubber "bumpers" on the rod between the top holder and the cartrige so the piston will not hit the valve a the bottom when the shock is "bottomed out".
If you or any one is interrested in more about this re-doing, just let me know.
