Hi, Not sure if I've interpreted your story correctly, but is it possible that you're trying to do the job without either: 1. Removing the splined axle that runs through the centre of it all (remove the spring clip and dustcap at the very front of the gearbox, screw in an 8mm bolt to make it possible to pry the axle forwards with a crowbar. Leave the axle hanging at the edge of the radiator), ... or ... 2. Sliding the slave cylinder out (held in by three allen key bolts) at the same time. Clutch doesn't come out otherwise. Be sure that the slave cylinder piston doesn't travel too far aft when you pull it all apart. You don't have to disconnect the hydraulics, as long as you remove the clips that hold the clutch line to the bodywork. Use Loctite on the three allen key bolts when reassembling. If I've mentioned the obvious by suggesting the 2 points above, then accept my apologies. Delete this mail ;-) Otherwise, I hope your chances have improved . . . Good luck, Robert Gothenburg (1983 900 GL, 1999 9-3 200) StepHydro wrote: > Well, > > I made a 4 mm thick ring tool that would fit under the pressure plate housing > abutments, thus holding the diaphragm spring fingers depressed.
