Military to Civilian Distributor Swap

Post by W_A_Watson_II »

OK, I know I've read bits and pieces about it, but does anyone have a good write up on how to do the Military to Civilian Distributor Swap (and Oil Pump as I understand)?

I ask because before I either rebuild the old PW's 230 or pick up a replacement, I'm considering swapping in the distributor and oil pump from the PW into the M's old 230.

How hard or how much work is this?

Thanks,
Will

Let me first say I love & totally agree with the paragraph about home land security, thanks for posting it.

As for the distributor swap, no big deal. The military oil pump shaft is designed to accept the offset tang of the military distributor shaft. The shafts of these components that were used in the civilian version of the 230 utilized centered tangs. It's simply a matter of changing out both components so that everything runs true. The civilian components install the same way as the military ones do. Once in place, just change out the spark plugs & plug wires, good to go.

Well, here's my 2 cents on your question, anyway. If you rebuild the military engine and swap to a civvy distributor, you'll lose the waterproof ignition aspect in addition to having to go to the effort of swapping out the oil pump and getting it timed right. My own choice would be to retain the military distributor and (maybe) install a Pertronix kit in it.

How hard the task of swapping out the oil pump/distributor would be depends on where the engine is when you do it. If it's in the truck, it will be a real pain to get to. If it's "on the bench," it's much easier to do but you'll then have to reinstall the engine. (The same applies if you decide to keep and rebuild the military distributor/oil pump.)

Charles,

Thank you, the recent events have caused me to re-value things and see if others see what I'm seeing.

So I should pull the oil pump and shaft out (from the opposite side of the motor) and swap it directly in, Thanks! I thought it was that straight forward from what I had read some time ago, but wanted to make sure. Will not be able to get to this until after the wedding next weekend, but preparing and planning.
Thanks,
Will

Lifer,

The "broke" 230 is still in the PW with the spun connecting rod bearing.

The 230 out of my M I re-powered with the Mopar V-8 is in a wood frame on the floor.

Either way the engine will have to come put of the PW to be fixed or replaced. I'd prefer to repair, but the engine is real tired and well worn (used a quart of oil for every 8 gallons of gas before breaking. the PW's engine is the original and correct engine number, which is also unfortunately the trucks VIN number, so if I do the swap I'll be having to get the title corrected to the frame number. If nothing else, perhaps the swap will at least let me get the truck back on the road while I re-build the original engine. I've also got a major Cab re-build/repair to do on the truck as well.
Thanks,
Will

The same procedure for installing the mil oil pump also works for the civilian set up. If you are not familiar with that procedure, get the pump in your hands & give me a call, can talk you right through it. Of course get the #1 cylinder up to TDC on the compression stroke before you start.
