Re: oil pump drive shoot me now

Good question - I think it has to go in from the bottom. There is a plastic collar that mates it to the oil pump (or steel collar) and I don't see how you could do this from above - but maybe someone has a tricky solution.

Nope...don't do it. I wouldn't cut any corners at this point if I were ou, you'll forever regret it. Suck it up and pull the motor to do it right. If it's a SB you can get the oil pan off with the engine in the car but that's a recipe for an oil leak...guaranteed.

Re: oil pump drive shoot me now

The retaining sleeve on the shaft that keeps it on the oil pump output shaft is too big to pass thru the hole in the block below the distributor. It needs to be done from the bottom, either remove the engine or you may be able to get the oil pan off in the car but not usuakky an easy to do. In most case the pan design plays a part in whether or not you can get it out. The flywheel also usually gets in the way also.

Re: oil pump drive shoot me now

You can take off the collar and use an extending magnetic thing and drop in the shaft. I have done this several times. You will have no problems dropping it in from the top.

For example: I have taken many engines apart that were assembled with the plastic sleeve and found them broken laying in the oil pan and they were still running with no problems.

I have also worked on engines that when I removed the distributor, the oil pump shaft was stuck in the distributor bottom with oil sludge. I just dropped them back in and everything was fine.

Patrick, No Offence, I hate to dissagree, and Yes it will work without the sleeve and it will run, BUT, if the sleeve is missing there is nothing to centre the oil pump drive rod on the pump. The rod will still drive the pump, but it tends to float? around a little and mark up the rod where it passes through the rear main cap as well as mark up the corresponding pump gear shaft tangs. The rods do not fit that tight in the bottom of the dist gear and they tend to wobble around, I have even heard them make a rattling noise with no sleeve. I had a 87 Iroc Camaro years ago that had this weird noise and I finally chased it down to no sleeve. The noise drove me crazy wondering what it was, as you allways think the worse case scenario.
I would pull the pan and put it in, GM and Melling etc., put them in for a reason. JMO.
