Engine Water Pump Mounting Gasket for John Deere 6081 (8.1L) / PowerTech Engines - Part Number: 74712105 (OEM Ref: R119383)

The engine cooling water pump mounting gasket (part number 74712105, original equipment reference R119383) is an OEM-standard replacement component engineered to provide a hermetic hydraulic seal between the cooling water pump housing (matched with water pump unit 74712104) and the cylinder block on heavy-duty John Deere 6081 (PowerTech 8.1-liter) and PowerTech series diesel engines. Manufactured from high-grade technical sealing media resistant to continuous thermal expansion, cooling circuit pressure, and chemical degradation from glycol coolants, it prevents leaks and pressure loss on high-horsepower tractors (7000, 7010, 7020, 8000/8000T, 8010/8010T, 8020/8020T, 9000/9000T, 9020/9020T Series) and harvesting machinery (11, 22, 6050, CTS, CWS, STS, WTS Series).

Key Features & Benefits

• Precision Die-Cut OEM Profile: Precision-manufactured to match the exact flange contour of the water pump and engine block coolant ports on John Deere 6081 engines, ensuring instant leak-free seating.
• Thermal & Chemical Resistance: Formulated to maintain elasticity and structural integrity under high temperature cycles and continuous contact with boiling engine coolants, ethylene glycol, and extended-life OAT/HOAT additive packages.
• Clean Dry Assembly: Designed for dry installation onto thoroughly degreased metal surfaces; eliminates messy silicone sealants that could extrude into cooling galleries and obstruct thermostat or radiator passages.
• Direct Interchangeability with OEM Ref R119383: Conforms strictly to factory John Deere dimensional tolerances and bolt pitch specifications for uniform clamping force distribution.
• Vibration Dampening & Clamp Load Retention: Absorbs harmonic vibrations inherent to large 8.1L diesel engines while maintaining positive bolt clamp load throughout demanding field operations.

Installation & Service Note: Thoroughly clean and degrease the mating faces on both the engine block and water pump flange, removing all traces of corrosion, scale, and old gasket remnants. Install the new gasket dry without silicone paste or grease, confirming that all bolt holes align accurately. Torque mounting bolts evenly in a diagonal criss-cross sequence to the torque specifications outlined in the John Deere service manual.
