If that is the case how hard are they to change, and will I have any problems finding a new seal? [Reply]   [No Email]

The hardest part of the whole deal will be keeping the tractor timed. Definitely get it up to TDC on the compression stroke on the #1 before you turn a single bolt. All you can do is pull the pump and figure out what's going on in there. Might be a seal. Might be an o-ring. Hopefully you can cross reference the seal and get a new one. You can get the distributor spacer that would've been in there originally and install that in the meantime. You won't have hydraulics but at least you can drive the tractor until you get the pump fixed. [Reply]  [No Email]

Machine shop work can get pricey , unless you know someone. Mine did that and I changed out the O Rings and it was good to go. I have seen that pump on a lot of old Farmall H&M tractors. Burgh Implement in Pa probably has at least a dozen or so laying around. He would fix you up for around $100 or so. Good Luck. [Reply]  [No Email]

M&W is one such company, and might be the manufacturer. Taking it apart will identify the seal type and if it has a number it will probably cross over to Chicago Rawhide, or National seal numbers. Motion Industries can help. It might have a worn groove in the shaft. If so it needs to have the new seal placed to not run in that groove or it will leak again. A product called Speedy Sleeve can repair the groove for a good seal. It will come as a Kit for the OD and ID of the seal. If it is an Oring seal (possible) and the shaft is grooved, it might require machining to allow the speedy sleeve to be used, and the housing to fit around it with a deeper Oring groove. Best of luck, and let us know how things work out. Jim [Reply]  [No Email]
