Overview
The ZF 4616.301.175 HOUSING is a precision-machined structural component designed for the WG 65 series transmission. This OEM genuine part serves as the primary casing that encloses the gear train, clutch packs, and hydraulic valve body, ensuring correct alignment and oil-tight integrity under high-torque loads. The SKU 4616.301.175 is engineered to withstand continuous thermal cycling and mechanical stress, making it a critical element for maintaining drivetrain reliability in heavy-duty industrial applications. When replacing this housing, it is essential to inspect the mating 4616101065: TRANSMISSION HOUSING for wear, as both components form a sealed assembly.
Symptoms of Failure
- External oil seepage at the housing joint: Cracks or warpage in the 4616.301.175 casing often cause transmission fluid to weep from the gasket interface, leading to low fluid levels and overheating.
- Persistent gear engagement delay: A deformed housing can misalign the shift rail bores, resulting in sluggish or incomplete clutch pack engagement during gear changes.
- Unusual metallic grinding noises: Internal bearing bore wear allows shaft deflection, producing a distinct grinding sound that worsens under load.
- Recurring fastener loosening: Distorted mounting surfaces cause the 0636011038: HEXAGON SCREW and 0636011118: HEXAGON SCREW to lose clamping force, accelerating vibration damage.

Compatibility
This housing is specifically engineered for the ZF WG 65 series, but it also fits select variants in the WG180 and WG200 families due to shared bolt patterns and bearing bore dimensions. It is directly compatible with transmissions using the 0636016015: HEXAGON SCREW for final assembly. Always verify the casting number on your existing housing before ordering. For auxiliary sealing, the 0634313118: O-RING and 0634801152: SEALING RING are recommended replacements during installation.
