My dad & I just installed an M&W 202PX pump on his Farmall H loader tractor. This video was useful just to make sure we didn't ruin anything removing the drive flange. I had to apply pressure to the flange and lightly buzz the drill center in the pump shaft with a small air hammer to get it off. I couldn't find any information on different magneto/distributor drive setups behind these pumps, but for some reason the pump distributor drive was an 1/8" shallower than the stock drive for the H4 magneto. The housings would mount up, but the magneto impulse dogs did not reach the output of the pump. Once the drive flange was off the pump, I was able to make a .11" spacer (and left out the c-clip) to put behind the pump output flange to space it out. The stock magneto and distributer just barely fits. We had to put the #4 plug wire on the distributor cap with it unmounted, then wiggle the cap & rotor as a unit onto the distributor body (routing a couple wires behind the oil filter housing) before clipping in the rest of the wires. We're probably going to hunt down some low profile 90degree spark plug boots to minimize the rubbing on the filter housing.

Could you tell us the seal number.?
Chicago Rawhide number 12424 M1, or MI. I can't make out the character after the M. I actually bought a replacement seal at Orilieys.
@@farmallerfa Thank you so much. That's very helpful.
