Oil pump intermediate shaft breaking

Dan the man said

I did investigate this same thing years ago and it was said then that pinned shafts are weaker.

I should have asked RRR too (he can read this and answer too) how many of these failures have you seen at the drive gear end?

I know I’ve run as high as 125 pounds of oil pressure and never failed a drive.

I also gave a theory about bronze gear wear. IMO most of the bronze gear failures are because cam thrust is not verified and corrected.

If it’s not corrected the cam can move enough that rapid gear wear occurs.

I can’t count the number of times I’ve had to machine a cam gear to tighten up cam thrust. Almost half of the builds have the thrust too loose.
