How to remove Lift-All coupler on M?

unioncreek · Apr 18, 2011

I need to put a new seal in the lift-all of my Farmall M. I haven"t pulled the pump yet, but would like to know how to get the coupler off the shaft to put the new seal in. I"ve had the pump off before to replace the seal in the tranny, but for some reason didn"t replace the pump one.

Thanks,
Bob

You need to drop the pump to remove the coupler, and you need to hold the coupler in place when re-installing. The pump and the coupler go in and come out at the same time.

You stick a bar in the fill hole and then turn the coupler off. I used a big screwdriver in the hole, but the rules state to use a brass bar. I then used a punch and hammer on the coupler to knock it loose. I didn't really tighten mine back up that much. No idea if I will have a problem or not.

after you drop the pump out of the tractor, you need to separate the pump from the housing.there are a ring of bolts holding the pump to the housing. you will need a new gasket for that and the drive coupling seal. when you separate the halves, there is a linkage that slides together to connect the lift all control to the pump, kind of a fork looking deal. if you look down inside the pump you will see a set of gears in there. that is where you slide the brass bar in there to lock the gears. i use a brass drift and hammer to tap the coupling loose. it spins counter-clockwise to loosen, then unscrew it out. replace seal, grease the seal a little, then put the new gasket on and slide the pump back on the resevoir housing, be sure to get the linkage to re-engage. while its apart, clean all the goo out of the resevoir and look see if the dipstick is laying in there too!!!

I replaced the seal on mine and it still leaked. The yoke was real grooved. I would recommend installing a sleeve all on the yoke when you have it apart if it is grooved.

Thanks Guys. I know you had to jam the gears, but
didn"t know the particulars.
