Which Oil Pump Priming Shaft have you used?

[Dean Prevolos]

I am looking to buy a oil pump priming shaft. I found the Genuine Mopar P4286800 Oil Pump Priming Shaft for $16.16 and the Moroso #62250 oil pump priming shaft for Chrysler for $16.79 , both on Amazon.

Has anyone used one of these tools to turn the oil pump in your 7.0 Hemi 426? I have my engine rebuilt on a stand for sometime now and want to turn the oil pump before I start it up.

Any other products you have used I am all ears. Thanks.

I have the mopar one for my big blocks and small blocks, works fine... Either will do the job just fine.

I used the Mopar shaft for many years and never any issues.

I made my own, about 45 years ago, took the gear off two stockers, cut the ends, welded them together. Still works just fine. But Summit has several available at low cost.

There is a hex shaft in a Frod A4OD automatic transmission that is exactly the same as the ones shown above. Just remember to put your drill in reverse. Ask me how I know.

A cut up old paint mixer. Had the correct hex shaft.

I welded a allen wrench to a piece of all-thread and it works well.

Go to McMaster-Carr. You can get a piece of hex stock for a couple bucks, have it the next day.

That company is great to deal with. They seem to have almost anything, even oddball fasteners.

Oil pump only runs in counter clockwise for Big Block and 2nd gen Hemi. Slant 6, small block and gen 1 Hemi are clockwise.

I made my own from an old shaft, just remember not to use something that can booger up the bushing in the block.

Bought a hex shaft. Used it put in my tool box it was in front of the drawer. Few years later went looking for couldn't see it with other tools there. Took a 2' piece of steel tube welded on a part of hex wrench and shaft other end. Liked it, didn't worry about accidently hitting bushing.

Seriously, all this fadoo about a friggen $20 hex rod that's going to see minimal use. Christ, buy the one with "free shipping" !!!

About 35 years ago I cut the top off a discarded 5/16" T wrench (used for setting up presses) and disc ground 3 flats for a drill chuck.

don’t do this folks, the all thread will scrape the bushing. And if the weld breaks for any reason you are on a bad fishing trip.

Use a solid shaft and make one yourself if it comes to that. I used a round rod and a die grinder, hex on bottom, 3 flats on top.

LOL no I was smarter than leaving the threads on it not a moron here. I had to do what I had to do.

Well the OP asked. I as other just made one. What they were asking for one 40 years ago was rediculus if you could find one. A trip to the local hardware store and presto a oil pump priming rod. No waiting week for the mail.
