Power steering parts for these old tractors haven't been available thru CNH dealers for a long time. An uncle of mine had to scour salvage yards 15-20 years ago to get parts because they weren't manufactured then.
That's funny.. I have gott many power steering parts from CNH. The pumps they sell are not 'like original'.. they are gear pumps.. not vane pumps.. but they bolt up.
I think your dealer was being lazy. I've walke din to a NH dealer before and asked for a part for my 8n, and had them give me the 'no longer serviced line' when i know for a fact that the part number is still good.
I just did a quick search in my master parts catalog.. as of least year, every part save gasket and reapir kits for the oem pump were listed as good numbers. The pump kits and assembly were listed as NLS, and had a superceded number for a different pump.. etc. .. This catalog covers the naa,501,600,700,800,900, 1801 model lines of tractor from 1953-1959
A 640 will have a manf date between 55 and 57.. etc.
Same PS is used on the 4cyl 2000/4000. A guy up the road is selling a 2000 with a newly repaired ps setup... guess where the parts came from? CNH...
