Help with small block oil pump driveshaft
« on: December 05, 2015 - 04:37:47 PM »

Darn smallblocks, I have no experience with them. Is the driveshaft to the oilpump supposed to be this loose? (se video link) or am I missing a bushing or something? The driveshaft in a big block does wiggle like this. Picture of the hole without the shaft.

I'm almost sure there should be a bronze bushing there, as on the bigblocks, never put a smallblock together before, so I figure I'll better ask...

Ah, thanks, machine shop must have took it out when they did the block. I'm glad I noticed, would not have been to cool trying to start without it!

Small and big blocks use the same bushing. I believe it is Pioneer brand that is made to be installed and run, vs the factory & MP type that gets installed and then needs to be burnished to the correct size using the right tool.

I got one, must have been a Pioneer then, it fit fine on the shaft and I installed it with no problems.
