You need to take distributor out and make a rod that fits in the slot of the pump like the distributor does. The other end will hook up to a drill electric or cordless whatever you got and spin away.

I've seen a couple different ways to do this.

1- Take a old oil pump drive shaft and cut the teeth off the drive gear then have a shaft with a slot on it to hook up to your drill.
2- Take the drive shaft out and get a priming shaft that goes direct to the pump from the drill.

OIL PUMP PRIMING SHAFT
Special hardened steel priming shaft fits on any 3/8" or larger drill. Insert shaft into hole where distributor fits. Pressurizes oil galleys to ensure against dry starts and ruining your engine.

P4286800 Oil Pump Priming Shaft (V8) $ 7.95

About 3/4 to the bottom.

same here. was hoping i could learn from somebodys elses doing! damn. thanks though. im gonna try to pull that gear out and hope i dont mess up the timing. everything is marked so it shouldnt go too bad as long as i divise a plan to get that drive gear out.

hey thanks for the info jbsjunk but im a step ahead. already tig-ed up my own tools just was not expecting to find this gearset inside the block. every other engine i have done the pump was ran directly off the distributor. guess im still learning the "jeep thing"

ive got the tool to prim mopar oil pumps! just used it on my big block its the same one as small blocks you just have to remember how the gear went when its time to put it back in or put it to TDC. i want to say u can use a peice of 5/16 hex rod like allen wrench but i dont know tomany places to get the rod at.

thanks. i took the gear out and primed it by hand. luckily the p.o had removed part of the firewall to gain access to the distributor. clearance issues like this make me wonder about the engineers designing this crap.

Engineers dont have to fix it. They just have to make it so it goes together easy.
