Farmall M rear end

Jerry RV · Sep 21, 2009

After draining the rear end of a M farmall, I need to fill it. The fill plug is stubborn and will not come out. Someone told me that I could pull out the shifter and put the 13 gallons through the shifter hole. Will this work or should I keep working to get the fill plug out?

An automotive service center would pump it through the check level hole. You could put together some 1/2" pipe nipples. an elbow, and a funnel and pour it in.

If I was in your situation, I would siphon it in. In fact, I just did that to my 400 as I thought it would to messy to remove the shifter and pour it. And holding up a five gallon pail at an angle for several minutes is tiring.

I bought a rotary style barrel pump for a buck at an auction. I used it again yesterday to put 5 gallons of oil in my 400s rear end through the right side shifter hole. without it I would mostly likely use a funnel with a hose attached and still use the shift hole to pour it into the Rear end. I think I tried the side hole once. SDE

Yes. If you can remove the shifter, pour the oil in that hole. It will end up in the same place.

I've had luck removing the plug with a 3/4" socket wrench or breaker bar. Have done this on a H, M & W6. - Mike
