Removing Gearbox Outer Cover

The gearbox outer cover is on the right side of the bike and has mechanism for the kick starter and the clutch cable termination point.

The cover is retained by 5, fillister head, slotted machine screws. Since these screws most likely haven't been removed for 35 years, it wasn't surprising that 3 were frozen. Two came free with a lot of pressure on the end of the screw driver and slow even application of torque turning the screw, the other 3 were stuck. Besides being slotted head screws and recessed the screws seemed to be of a fairly soft metal as using a drift on one to try and break the binding free resulted in the slot on one screw closing slightly. Fortunately I was able to get the screw drive blade back into the slot. A combination of lots of heat and sacrificing a chuckable flat bladed driver to fit in the screws slot and then hammering it, they came free.

Not surprisingly a bit of water leaked out the bottom before the gear lube spilled out when the cover was removed.

Of concern is the sizable amount of metal filings in the outer cover. It has me wondering what I'll find when I open the gearbox itself.
