wobbly oil pump shaft?

i am currently putting a vortec headed 350 in a friends van and im also putting in the disributor. i try to stab it in and it will only go so far and then stop. i have had it in all the way a time or two but it was in the wrong postition. today i was trying to adjust the oil pump shaft and i noticed that it wobbled a bit in the block. could it be that the oil pump shaft is misalligned and stopping the distributor from seating all the way? i have never had this much trouble putting a distributor in (i have done it a few times).

Re: wobbly oil pump shaft?

Look at the bottom of the dizzy, there's a flat blade (like a screwdriver), it fits into a slot in the oilpump drive, it sounds like the slot isn't facing the right way. Take a looong screwdriver and turn the oil pump shaft as needed to get the dizzy in all the way.

The wobble is normal. The distributor gear will hold it when installed.

Re: wobbly oil pump shaft?

yea it has the slot and the distributor is a brand new accel distributor. i have also spun the shaft with a screwdriver in just about every direction. its just extremely frustrating but atleast everything is ok.
