a complete pump for a power**** is $1,200. Maybe it is just me but that does not sound horrible for a 155 hp tractor. You would not see any major difference in a similar vintage case, massey, etc in fact are probably more if still available. If the tractor is in good shape then it is a relativly small investment in the overall value of the tractor which is still a very desirable unit. The other big salvage yard however is bridgeport tractor parts, I don't know that you will find a re-man gear pump.
