TC Pump differences

Postby havoc1482 » Wed Dec 02, 2015 2:48 pm

How many different variants of the pump were made? I know of at least two, but the two pictures on the Case/IH Partstore look different from the one I just salvaged. The 2 bolts that hold the manifold on this one thread directly into the pump body instead of through it with a nut on the other side like the current one on my Super A. The 2 on the Partstore look like the bolts go through to a nut as well. Could this have been a variant for a later model tractor?

Havoc, There were four different manufacturers, mostly similar , but some differences in seals, orings, gaskets.
They were Thompson, Cessa, Pesco, and Wooster.The only one of mine I have had apart is a Pesco, P#360687R91.
(An old CNH parts breakdown I have shows a Thompson 360945R92 and W/W for 3603689R96, 355007R94,and 355370R93)
I replaced the oring from a hydraulic shop. It was not oval, rather round, but I was able to form it in the oval grove and it works . BTW, the CNH parts breakdown was several years ago before they "improved " the online parts site. I have IH part #s for a couple of pumps if you can describe the part, I may be able to figure out the part#, but it is probably NLA

BTW, (got sidetracked), on mine, the bolts go through both halves with nuts on the end.

Stamped on this one is P24EZ5G2R03 and below that number is 383014R93. There is the number '20' inside a diamond below those and even farther below those stamps is '7 65K'. The opposite side has 'T18' inside of a circle.

Well, that leaves me with no helpful ideas. It looks like my Pesco but that isn't any help.

Bear in mind that the same hydraulic pumps were used on all 113/123 engines with hydraulics. SA, C, SC, maybe others.

Old on the right, "new" on the left. I just noticed the differences in outlet diameter, is that going cause a pressure problem with my TC block? All the dimensions are the same, it will fit, I just need to get some new coarse thread bolts, old pump ones are 1/4 inch too short and 2 for attaching the manifold.
