Caterpillar 215-8708 Water Pump Assembly

The Caterpillar 215-8708 water pump assembly is engineered to maintain optimal engine operating temperature for Mitsubishi 4D31T series diesel engines. It features a precision-machined cast iron housing with a stamped steel impeller and a high-performance ceramic-carbon mechanical seal designed to withstand high coolant pressures and thermal cycling. This unit is a direct replacement for Caterpillar excavator models E70B, E307, and E110B. The pump is belt-driven from the engine crankshaft and incorporates a sealed bearing assembly lubricated for life. Cross-references include Mitsubishi OEM ME080647 and aftermarket identifiers CA215-8708 and GWM-33A. Each unit is pressure tested to verify leak-free operation and flow capacity prior to shipment.
