Engine Water Pump Sealing Gasket for John Deere 6076 / PowerTech Engines - Part Number: 74712109 (OEM Ref: R96616)

The engine cooling water pump sealing gasket (part number 74712109, original equipment reference R96616) is a precision OEM-standard replacement component specifically engineered to provide hermetic hydraulic fluid containment on the cooling circuit (matched with water pump assembly 74712106 and associated cooling line seals) on heavy-duty John Deere 6076 (7.6-liter) and PowerTech diesel engines. Formulated from advanced technical materials offering exceptional thermomechanical stability and chemical resistance, it maintains leak-free sealing under system pressure fluctuations, preventing coolant loss across heavy-duty John Deere row-crop tractors (7000 Series, 8000/8000T Series, articulated 60/70 Series) and combine harvesters (CTS and Z Series).

Key Features & Benefits

• Precision Hermetic Sealing: Precision-engineered contour strictly matches factory John Deere tolerances, ensuring uniform surface contact and zero risk of high-pressure fluid seepage or extrusion.
• Thermochemically Resistant Material: Formulated to maintain elasticity and structural integrity during continuous exposure to boiling engine coolants, ethylene glycol, and modern extended-life OAT/HOAT additive packages without hardening or degrading.
• High Compression Set Resistance: Exhibits superior recovery under continuous clamp load, preserving positive sealing pressure across severe engine block thermal expansion and vibration cycles.
• Direct OEM Interchangeability: Fully compliant with original John Deere dimensional and material standards, serving as a direct drop-in replacement for OEM reference R96616.
• Clean, Paste-Free Installation: Installs smoothly and cleanly onto degreased metal surfaces without liquid sealant or petroleum greases, preventing accidental contamination of cooling passages.
