Convert bolt on pto pump to spline type

roman · Oct 13, 2010

I am in the middle of buying a Yancheng 9' 3pth backhoe. As I was helping the seller ready it for me to transport I realized the pto pump mounts to his secondary pto with 4 bolts. I have payed for this unit and need to make a decision weather to back out of it. It's looks to be in great shape. $1200

I need to know how difficult and how costly this conversion would be. I saw some Prince pumps on line last night for $500. I imagine the threads on the hoe's lines aren't SAE. It is going on a Ford 1720 4x4 with FEL and Sims metal cab.

Any advice is appriciated however I cant afford to buy a new one or a Woods or Wallenstien.

Thanks.

If everything else is there, you will spend the cost of the pump and the cost of a new pressure hose from the pump to the backhoe control valve (3/4"?)and a new suction hose from the reservoir to the pump (1" or 1 1'4"?). The backhoe control valve and reservoir fittings may be metric or (more likely) British pipe thread, but adapters are not hard to find.

The Prince pto pumps (with cast iron center section) are roughly $500, and there are clones (Chinese?) for $100 to $150 less. I have no information on the clones, but I have two Prince pumps and they are first class. $100 should more than cover the cost of the new pressure and suction hoses and adapters.
