6.2 oil pump prime

[MilitaryRestoration]

How do you go about priming the oil pump in a m1008 6.2l diesel...have done on small/big blocks but never a diesel...

On 6.2 for hmmwv's, you remove the rear electrical tack and then use a drill to turn the oil pump shaft. On hmmwv's you have access to the rear of the engine easily, on m1008 you may not. Another way is remove the glow plugs, squirt a little amount of marvel oil into each cylinder and then with the glow plugs REMOVED, turn engine over in 10-15 second bursts. No compression, no load on starter, engine cranks very fast. Stand clear of the glow plug ports for the marvel oil will squirt you! I have done this on a few engines and with the electrical connected you should register oil pressure on your gauge. Once you start the engine and have good oil pressure, do a high idle to lube the rails sufficiently. Good luck! My .0

the above is very similiar to the m1008 procedure. the cucv has a vaccum pump in the place of the tach of the hmmwv.

so how do I go about spinning it with the drill?

Look at the end of the vacuum pump that you just removed, it has a hex head securely tape the approate socket on the end of a long extension, the oil cooler must be connected, because the oil goes from the pan through the pump through the cooler though the filter and then to the bearings, about two quarts of oil.

you can also get a bad vacuum pimp and customize it for the job
