Engine Coolant Water Pump with Gasket for John Deere Tractors & Combines (6076 / PowerTech Engines) - Part Number: 74712106
The engine coolant water pump (part number 74712106, original equipment references RE68230, RE500214, RE49540, RE68229, RE39121, RG28370, supplied complete with sealing gasket) is a heavy-duty, OEM-standard mechanical hydraulic component engineered for forced coolant circulation on heavy-duty John Deere 6076 (7.6-liter) and PowerTech diesel engines. Equipped with cavitation-resistant sintered mechanical face seals, high-load sealed double-row bearings, and a rugged cast housing designed for high thermomechanical stress, it guarantees optimal heat rejection away from the engine block and cylinder heads under sustained heavy loads, preventing overheating and downtime on high-horsepower tractors (7000 Series, 8000 Series, articulated 8560/8570) and combine harvesters (CTS and Z Series).
Key Features & Engineering Benefits
- Hydraulic Calibration for Large Displacement Engines: Impeller vane profile is hydrodynamically balanced to maintain uniform, high-volume volumetric coolant flow even at low engine RPMs and under peak draft or PTO workloads.
- Supplied Complete with Dedicated Gasket: Includes a precision-cut mounting gasket to guarantee instant hermetic sealing against the engine block face without unauthorized liquid gasket compounds.
- Heavy-Duty Sintered Mechanical Face Seal: High-hardness friction faces resist abrasive wear, coolant crystallization, and chemical degradation from traditional ethylene glycol and organic acid technology (OAT/HOAT) formulations.
- High-Capacity Double-Row Ball Bearings: Sealed-for-life bearing assembly is built to absorb continuous high radial tension from auxiliary drive belts without developing axial play, shaft tilt, or rotational noise.
- Direct OEM Interchangeability (Plug & Play): Flange geometry and mounting dimensions are precision-machined to factory John Deere tolerances, serving as a direct drop-in replacement for OEM codes RE68230, RE500214, RE49540, RE68229, RE39121, and RG28370.

Installation & Service Note: Thoroughly drain and flush the entire cooling system before replacing the water pump to eliminate abrasive particulate matter, scale, and rust deposits that could compromise the new mechanical seal. Thoroughly clean and degrease the engine block mounting surface. Install the included gasket completely dry without liquid paste or silicone grease. Torque mounting bolts in a diagonal criss-cross sequence to the torque specifications outlined in the John Deere service manual. Refill with approved coolant, bleed the system to remove air pockets, and run the engine up to operating temperature to verify hermetic sealing.
