more M hydraulic help

Dim Pete · Jul 14, 2018

Hi, you guys helped me out a week or so ago with replacing a seal and priming an M hydraulic pump, thanks to your help it worked out fine.
Unfortunately I have another M I bought from a friend so I could get the mower and cultivators from it, then resell it. But this one also
started to get hydraulic oil in the crankcase and the the lift was very jumpy. I wanted to fix it before I sell it. I took the pump
apart and the pump drive shaft has sheared off the woodruff key and the shaft is kind of beat up. Tractor serial number is 15456. Parts
book says part number is M503T, Worthington ag parts has one for $55. Do you know anyplace else to get one? thanks again.

here I hope are some photos of the gear if you could help me identify which one I need. I guess there was an update kit used on some pumps?

Rusty acres ranch or Dave Cook but you probably won't get a better price. I would be concerned about what caused it. You have some sideways wear on the housing so bearings are worn and probably the gears.

If it hasn't been changed it will be a two piece pump with plain old pipe lines. If it's a three piece you will need to get the housing numbers and reference the parts book. It is available to download free from jdparts.com. The update was for adding a loader and then they all went to the three piece at a later serial number. Even the number series will fit on there with a line change.

Wow that has some damage. I would look at getting the part from Rusty Acres. You can get an entire pump from them for around $100 plus shipping. Like M-Man said what caused that and is there other damage and scoring inside? You don't want an angry buyer coming back.

I am thinking of getting one from Rusty Acres, I may also get a quote for having this one rebuilt. Thanks.
