Ford 4500 Hydraulic Pump repair

4500/555 · Jul 10, 2022

I have a Ford 4500 1974 industrial tractor with a backhoe. The hydraulic pump is leaking and I would like to rebuild it. The rebuild kit part number is D6NNE999A which supercedes to the new part number 893496C1. I am having trouble locating a kit in stock. Does anyone know of a source to come by one of these kits? Any help I can get would be greatly appreciated!

There are 2 different pumps used. A vane and a gear. Just replace either one. A seal will do no good as the wear in gear section will defeat the purpose. Vane pumps are not that expensive. The most important thing is the port orientation and spline size and count.

If it is a Cessna pump take it to a hydraulic shop. There are numbers stamped all over it, anyone with access to Cessna parts can I.D. it. Another possibility is if you are merely trying to leaks you can buy a couple o-rings to seal up the body-to-end plate sections, and a new shaft seal. Long as the pressure plate and diaphragm are in good shape they can be reused. O-rings and seals can be had from Baum Hydraulics in Nebraska.
