Notice the wide range of the depth above or below the pump surface.
I know @jakeraby pointed this out long ago but is there an easy fix or just use new pumps? These are cores that are getting reworked. Attached thumbnail(s)

"Outward" meaning "in" toward the engine? Doesn't seem like it can walk "out" toward the cover, it'll just stop there.
So where's the failure in this design? Inconsistent shaft length? It seems that if there's risk for the shaft to walk toward the cam, then that should have been a blind hole that the shaft sits in (with a hole for draining, if needed. Pinning the shaft to the housing and letting the gear spin on it seems the "easy" button (it really isn't that difficult a machining operation). |
