Quiet shocked only got about 25ml of oil out so had lost quiet a lot.
Drained left fork leg or I mean I removed the drain screw only to find NO oil came out at all !!! Guess that explains why it wasnt leaking !
Stripped and cleaned out all forks ,there was someoil in there so some lubrication going on.
Very small stone chips in chrome at top of travel in forks, cleaned up very carefully with 1000 grit wet and dry with WD40.
I made a tool to hold the damper unit with an old socket and a 27mm head sized nut welded together.
My homemade fork tool
Had to try and think of a way to put the top bush and seal in without the driver tool ... Cut off the end of a used mastic cartridge this was just the right size to fit over the seal :)
Any way all back together now and fill with the correct amount of oil
