Engine Water Pump O-Ring Seal for John Deere 6076 / PowerTech Engines - Part Number: 74712107 (OEM Ref: R101042)

The engine coolant water pump toroidal O-ring seal (part number 74712107, original equipment reference R101042) is a precision OEM-standard elastomeric sealing component specifically engineered to provide hermetic radial hydraulic containment for the cooling water pump assembly (matched with water pump unit 74712106) on heavy-duty John Deere 6076 (7.6-liter) and PowerTech diesel engines. Molded from an advanced, highly resilient elastomer compound with superior thermochemical resistance, it guarantees consistent leak-free sealing under system pressure cycles, 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
  • Calibrated Precision Radial Sealing: Precision-molded circular cross-section matches factory John Deere tolerances, providing optimal interference fit inside the mating groove without risk of pinching or pressure extrusion.
  • Thermochemically Resistant Elastomeric Matrix: Formulated to maintain elasticity and structural integrity in continuous contact with boiling engine coolant mixtures, ethylene glycol, and modern extended-life OAT/HOAT additives without hardening or flaking.
  • High Elastic Recovery (Low Compression Set): Exceptional resistance to permanent deformation under clamp load, maintaining positive radial sealing force across continuous engine thermal expansion cycles.
  • Direct OEM Interchangeability: Fully compliant with original John Deere dimensional and material standards, serving as a direct drop-in replacement for OEM reference R101042.
  • Clean, Paste-Free Installation: Installs smoothly into the housing groove using only a light coating of clean coolant for lubrication, completely eliminating messy RTV sealants or petroleum-based grease.

Installation & Service Note: Clean and degrease the mating recess on the pump housing or block face, removing all corrosion, limescale deposits, and old rubber particles. Moisten the new O-ring evenly with fresh engine coolant to ease insertion and prevent twisting, pinching, or cutting during pump bolt torquing. Never use mineral petroleum greases or RTV silicone sealers.
