JMP Yanmar Replacement Engine Cooling Pump #JPR-YM08IH
- Steel Pulley & Mounting Bracket
What is the internal difference between JPR-YM08IH and model JPR-YM08IH2?
The difference is the thickness of the machined "Cam" which is incorporated or part of the Body / Casing itself. The machined thickness of YM08IH is greater (4mm) vs a smaller thickness (2mm) found in the JPR-YM08IH2, so the JPR-YM08IH model will give a higher flow rate vs JPR-YM08IH2. This is why it is very important to order the correct pump for your model of the engine by referring to the cross-reference information provided.
You can also use JPR-YM08IH for the replacement of Yanmar 121575-42000 (replaced by 721575-42702), which is the pump with the NPT threaded nipple port design, but you MUST make sure that you have the rubber hose for the inlet and outlet for the JPR-YM08IH hose connections.
How to Install Mounting Bracket on Pump?
