Oil pump drive Question

[Missing Link]

I'm stripping down my original engine to find out what caused the bottom end to let go.

It's picked up badly on the No 3 shells ( Along with some others ) but i've noticed the oil pump drive wheel for the pump is spinning on the crank, It's only stripped down so far so can't see it full yet, How does this gear mesh with the crank ? is it keyed or is it on a taper ?

Really need to get a manual.

Cheers

Was this the problem?

 

[sideways danny]

the pump sprocket will spin freely until the crank pulley bolt is torqued. It's held with tension, like all the other pullies

Not Sure fella, I think the drive wheel floats on the crank, Anyway No3 big end bearing got fried....Big time.

Got another crank here to build it back up.

Will be in touch soon about that g/box rebuild.
