J854D 137 #2 Posted September 30 (edited) The model & serial numbers on the tag in your pics show that it is a 1974 D180 tractor. I’ll bet the pump would be the same as the one on your 1977 D200. (If not, then very similar) It would be best to search the files section on this forum for an IPL (illustrated parts list) for each tractor to see if the part numbers for the pump match. -JD- Edited September 30 by J854D 1 1 Share this post Link to post Share on other sites
daveoman1966 3,752 #3 Posted September 30 The Wheelhorse 'D' series ---D160, D180, and D200 all use Sundstrand Piston-to-Piston pumps of the same construction. There MAY be shift linkage differences, but the pumps are the same. Here is an overhaul manual I made that may help if you are doing a rebuild...which, after 50 years in service, is probably over-due.
