More pics then, Wobblywalrus!!!

Crank and its 2 main ball bearings (there's also a 3rd one between the drive gear and the outside flywheel, located inside the primary cast alloy cover)



#114 again...



The small TJ stamp found on all the machined parts:



Found opposite the above one, an even smaller stamp, was lucky here on the oil pump drive gear, it is usually totally unlegible...



Bronze bodied oil pump and ancillaries:



I then tried to pull out the clutch holding plate, no luck... Rather than do sommat silly, went and done the small alloy plate to bring the magneto to the right hight, about 1/8" thick:







Bye for now, have a good Easter break...

A day more was enough to come up with the goods to get the final bits of the gearbox out...



Four ball bearings in there, with three being obsolete, made out of unobtainum...

Clutch bell one:



Two similar ones, big diameter and dead skinny, that support the secontary gear assembly, all made in one piece:



And as usual with "crash" gearboxes, 2nd gears are well worn out. I will visit a local gear manufacturere to see what can we do to renew them...





See you around, back to work tomorrow... : O (
