Product Description
CUMMINS 4934041 OEM TIMING GEAR CASE HOUSING – ISB 6.7L (2007.5–2018)
The genuine CUMMINS 4934041 OEM timing gear case housing is the factory front cover assembly that supports and aligns the timing gears on 2007.5–2018 6.7L ISB Cummins engines. This component forms the structural front section of the engine, maintaining correct gear mesh, oil channeling, and crankshaft sealing. When cracked, worn, or damaged from prior repairs, replacing the gear case with a real Cummins OEM unit ensures accurate gear alignment and prevents catastrophic front engine failure.
Heat cycling, vibration, front main seal leakage, accessory stress, or previous timing service can distort or damage the original housing. Installing a new 4934041 timing gear case restores OE tolerances, maintains proper front-end geometry, and ensures long-term durability for high-mileage and work-duty 6.7L Cummins trucks.
