Hi Jeff, The clutch is right hand thread, from memory take the perforated cover off and with a cold chisel give it a hit on one of the ears the 3 screws came out of and it should undo fairly easily. Been a while since I have pulled one of the flywheels off, can't remember if I had to tap threads into the 3 holes in the top of the wheel, probably had to. Then I have a piece of 3mm plate about 100 mm square I drilled 3 holes to suit the 3 in the flywheel with a 10mm hole in the middle. Put a bolt through the hole with a nut on the underside, screw 3 screws through the plate into the top of the flywheel, then tighten the center bolt up and get a fair bit of pressure on it and if it doesn't break free give the center bolt head a hit with a hammer and it should pop off. The key will often flick up and catch on the inside of the magnet in the flywheel. You will also need the nut to go with the new flywheel setup
