description: Pulley 8 Groove, Power Steering For HMMWV M1114 12469471, 3020-01-488-5635 Description: The Pulley, Power Steering (NSN 3020-01-488-5635, P/N 12469471) is an 8-groove serpentine belt pulley manufactured by AM General. It is made of steel and is designed specifically for the heavy-duty serpentine drive belt system found on later-model, up-armored HMMWV. Outer Diameter: 6.01 inches (approx. 152.6 mm) Total Width/Thickness: 1.41 inches (approx. 35.8 mm) Bore Diameter (Inner Shaft): Standard 0.668–0.75 inch GM press-fit spec with integrated keyway slot. Type: 8-Groove Serpentine / Flat Belt Pulley Material: Steel Application: Power Steering Pump Configuration: Press-fit (typically requires a specific installer tool for the pump shaft) [1, 2] Engine Application: This pulley is used on the 6.5L Turbo Diesel V8 engine (often referred to as the 6.5T or GEP engine). It is part of the upgraded serpentine belt drive system introduced to support high-output accessories (like the 200-amp and 400-amp alternators) required by up-armored variants. Vehicle Models: It is primarily used on ECV (Expanded Capacity Vehicle) and REV (Reliability Enhancement Vehicle) HMMWV models, typically those with serial numbers 196901 and above. Common models include: M1114 (Up-Armored Armament Carrier) M1113 (Expanded Capacity Vehicle) M1151 / M1152 / M1165 series M1097A2 (Heavy Variant) Note: This pulley is distinct from the 4-groove V-belt pulleys found on older, naturally aspirated 6.2L and 6.5L HMMWVs (like the basic M998).
