belly pump seal

Finnbair2020 · Apr 27, 2011

I have a question about the hydraulic belly pump on a 1948 M. The belly pump is removed-- trying to repair the seal on the drive. To replace the seal, the drive needs to be unscrewed. Is it threaded left or right?

What is the easiest way to get this unscrewed?

[b:fe0e30da84]its right hand thread. Ill try to make this understandable... I took a piece of keystock the same size as the one on the coupling and welded a nut in the middle of one of the sides. Take this "tool" and put it in the coupler, then take an impact gun and remove the coupler. You'll also need to take a long screwdriver to jam the gears so they dont turn when you try to remove the coupler.

then when you go to put it back on, you cant jam the gears (since your turning it the oppostie way) so it just takes a few short bursts with the impact to get it back on. Once you get it back in the tractor it will "torq" itself down.

Hope this helps. I can get a picture of my "tool" I made tomrrow and post it up if I totally confused you.[/b:fe0e30da84]

a BFH works too lol but it wont work when you go to replace the pump drive seal in the trans. housing.

I just used a big screwdriver to jam the gears and a punch and normal sized hammer to get the coupler off. They aren't very tight.

Make sure the yoke is in good shape. Mine still leaked after changing the seal. I would put a sleave all on it if the shaft is grooved.
