Re: need G50 clutch install help
Howard, I can't help with the guts of the clutch itself, but I have had more experience than I wanted with the release fork & g/box r&r !
As Chris says, once the locking tab has been removed, the fork shaft "should" just slide out - mine didn't. I ended up cutting a couple of short lengths of steel tube with an ID just larger that the shaft dia. Place the tube over the outside end of the shaft & use a large dia washer to cover the end of the tube. Then run a suitable bolt thru the washer & into the threaded hole in the shaft (5mm, I think). Tighten up the bolt & it pulls the shaft out. Mine was very tight & I had to use a second, longer tube to get it all out (travel is limited by the depth of the threaded hole in the shaft).
The re-installation of the fork & shaft as you are installing the g/box can be a nightmare, BUT, can be made a whole lot easier by :
a) grinding a 2mm chamfer around the blind end of the shaft - this makes it so much easier to get it thru the fork bearings & into the far-end bell-housing bearing. (Remember, you are doing this with the g/box closed up to the adaptor plate, so access is only via the small openings in the bell-housing).
b) when you slide the g/box into place, you need to suspend the release fork so that the fork lugs are in front of the release bearing lugs & all is centralized. Bill Bayard gave me the clues on this one - suspend the fork by running a number of elastic bands under the fork lever & up to the ring-gear teeth. You can centralize the fork my moving the elastic bands over the teeth of the ring-gear as required.
c) Once the g/box is mated up, you can twiddle the lower end of the fork to get the shaft to go through the fork bearings, then into the RHS bell-housing bearing hole (hugely easier if you have the chamfer on the shaft as per (a) above).
After this, I usually (how depressing to have to use that word !) pull as much of the elastic bands out as I can with a hook on a coat-hanger, then let the starter motor grind up the rest.
I hope that this helps a bit.
