Parts Manunal Help Needed

I have a 1968 (April) Ford 3000 tractor but no manual. I need to replace the power steering pump and am having a hard time finding the OEM part number. The number on the pump is C7NN3N675E but I can't find it anywhere. Does anyone have a manual that could tell me the OEM number or have any suggestions? Thanks.

That number on the pump probably isn't going to help much. Ford never shipped tractors with the part number actually on most parts. If anything, there was a casting number, which isn't a part number at all, or an assembly line stocking number, which is similar to a part number, but just one that was used on the assembly line, and the part number to go buy a replacement at a dealer was a completely different number.

Mike provided the link for the on-line parts site, so you should be good there. If it is the original power steering pump in an April 1968 3000, then the steering pump should be the earlier design with the external reservoir up above the pump body. They changed to the pump with the reservoir integrated into the body of the pump in October 1968.

The part number for the original pump was C7NN3A674C, which was superseded at least a couple of times over the years, and the latest incarnation is 81816576, but I don't think that they are available from CNH any longer, but searching on the earlier part number returns a number of sources for after market pumps that claim to match that part number. Just make sure that you get a pump that has the relief valve set at 650 psi, as that is what the power steering system on your tractor was designed for. They made them with relief valves set at 850 psi and 1100 psi for other tractor models, but those can cause problems in a system designed for 650 psi. If you cannot find a 650 psi pump, you can swap out the shims in the relief valve to get the desired psi setting.

The link helps a lot. Thanks. Will see if I can find it.

Here's the LINK to CLYMER MANUALS. They are the new owners of the old INTERTEC PUBLISHING, I&T Company, who are no longer in business. CLYMER can retain the name "I&T" per the buyout agreement and reprint the manuals exactly as the last revisions were including the manual numbers. FWIW: FORD 9N,2N, and 8N = F-04; Ford NAA/Jubilee = F-19; Ford 600/800 = F-21; Ford 2000, 3000, 4000 and more = F-31. Hope this helps.

If it were me I would consider changing
your pump over to the new style integral
one. The new style costs about $150 at many
places and the old style will run you most
of $400.
You will have to change the lines but any
decent hydraulic shop could help you with
that.
