Frequently Asked Questions
Which water pump fits a Case 188 or 207 diesel engine trencher?
The Diesel Engine Water Pump A146584 is built for Case 188 and 207 diesel engines and fits W series and DH series trenchers including the W3, W5A, W11, DH5, and DH7. It circulates coolant through the engine block and radiator to keep the engine at operating temperature. Match the part number to your engine to confirm the correct fit.
Do you carry a water pump pulley for Case trenchers?
Yes, Broken Tractor offers the Case Water Pump Pulley G11339, which fits W3, W5A, W11, DH5, and DH7 trenchers along with the same engine family as the diesel water pump. We stock both complete water pumps and matching pulleys so you can replace the full cooling assembly. Confirm your engine and serial number if you are unsure which pulley you need.
What is the difference between the gas and diesel water pumps for Case trenchers?
The Case Gas Engine Water Pump A148401 is built for gas engine cooling assemblies, while the Diesel Engine Water Pump A146584 fits Case 188 and 207 diesel engines. Choose the one that matches your engine type. If you are not sure which engine your trencher has, the parts team can help you match the correct part number.
How do I know which Case trencher water pump I need?
Match your engine type, gas or diesel, and confirm the fitment against your model and serial number, since coverage varies across the DH and W series machines. The diesel pump A146584 and pulley G11339 both cover the W3, W5A, W11, DH5, and DH7. For help confirming the right part, call our team at (800) 909-7060.
