Hi guys,

When I bought my M last fall, it was missing the PTO-to-belly pump coupler. I finally got that installed today and now I think I'm ready to get this baby up and running.

I drained it today and added about 6 quarts of fresh fluid. No leaks so far, and the unit itself seems to be in good shape. I ran out of fluid or I would have added the full 8 (I think that's the capacity).

At any rate, I know nothing about hydraulic pumps. There are obviously missing pipes on my unit, but I don't know what should fill them. Here are two pictures:

All I know for sure is that the tube circled in green in the "right side" picture is the fill tube, and that it's missing a vented cap of some kind.

Can someone help me make a list of the hardware missing from the pump? What pipes and caps do I need? How can I test the pressure? Do I need hoses?

I'm an idiot, too, by the way, so please speak slowly to me when you explain these things. Seriously.

Thanks in advance,

billOH

Bill, In case you weren't able to find the hydraulic cap and dip stick I just saw a set on EBay, Item 7546651782. It list the p/n for the cap as 5047E which is the correct cap for a M but doesn't list the dip stick part no. The correct dip stick part no. s/b 15158E with a possible additional alpha character at the end. Also, I looked in my M owners manual and the pump capacity is 6 quarts. It should be filled with everything in the lowered or "relaxed" position. If you overfilled it you might want to drain out anything over 6 quarts.
Hope this helps and maybe you had a successful trip to the salvage yard for the needed items. Good luck. Hal

Thanks for you help, gentlemen. I will stop by the local tractor salvage yard this afternoon and see if they have the needed parts.

Bill, you are missing quite a few parts but they should all be easy to find. The fill pipe on top should be a piece of pipe 3/4" dia. by 3 1/4" long. You also need the vented cap you mentioned. Orginally it also came with a dip stick but rarely seen on many tractors after 50+ years. One could be made from a stiff piece of wire if desired with a couple of scribe lines to indicate full and a quart low. The three outlets on the sides are welded fittings from 1/2" pipe nipples and 90 deg. elbows. They are all the same according to the parts catalog. In addition to these fitting parts all torque tube penetrations also have a felt dust seal, a steel washer and a spring to cover up the balance of the opening from dust and dirt. The control rod opening also needs the same items. The fill and control rod openings need a larger size then the outlets. I would suggest the Nebraska Cowman who is a regular on this forum for the fitting parts. His email is howster@nebnet.net. The dust cover pieces I noted can be obtained from Ron Berlage at Pilot Knob Restorations as they are listed in his catalog. Ron can be reached at (815) 777-0826. They are not available at CaseIH. You can determine any hydraulic hoses you need and obtain them locally at a tractor supply type facility as they generally always make custom hydraulic hoses. From reading other posts on this forum, I would suggest you not operate the system with it capped and without hoses. It seems without some relief somewhere in the system you are prone to blow gaskets and start leaks if operated with the caps in place and not hooked up to something which can absorb the pressure.
Hope this helps and have fun. Hal
