NCA600F-GP Hydraulic Gear Pump
for 1953-1964 Ford Tractors
!!!NOW BUYING CORES!!!
Supply chain interruptions have resulted in a limited availability of new aftermarket NCA-905C piston pump housings used in the conversions. The housing manufacturer has indicated new housings will not be available again until sometime mid-year 2021. Consequently I am buying good used NCA-905C piston pump gear housings. If you have housings you would like to sell please contact me at: email@example.com or call me at 301.655.0631 (any day 7 AM to 8 PM EST)

Drive Gear Housing
Windy Ridge Farm and Machine has designed a simple conversion kit that replaces the vane and piston pumps with an inexpensive, reliable, and industry standard gear pump. The gear pump is fitted to the end of the Ford NCA905C hydraulic pump gear housing in place of the Ford piston pump body. The OEM gear housing is not modified and the gear pump is driven by a professionally CNC machined intermediate shaft that replaces the original piston pump wobble shaft (see Figure 1). An aluminum adapter plate is used to transition the Ford piston pump four bolt pattern to the industry standard SAE-AA two bolt mounting flange on the gear pump.

The NCA600F pump conversions come fully assembled as shown below and a parts only kit is also available for customers with OEM piston pumps that wish to save money and do the conversion themselves. The converted pump can be installed in about an hour using just a few common hand tools.
