Title: oil pump drive worm
Post by: kev on 27 Mar 2016 at 12:08


  1926 ew   the oil pump drive worm....I have about 1/2 inch of threads outside of the pinion gear...is this about right??
I have the threaded worm to drive my oil pump... is that all it threads on to?? 

I have heard about a spring and disc in the crank pinion end...could I get a picture...drawing ?  of that and where it goes??

also the oil slingers on the ends of the crankshaft...are they similar to BSA??
