ZF 4616.301.307 HOUSING for WG 65 | OEM Genuine Part

Overview

The ZF 4616.301.307 HOUSING is a critical structural component engineered for the WG 65 series transmission. This OEM genuine part encloses the hydraulic control unit and planetary gear sets, providing precise alignment and sealing for optimal oil flow. As a central casting, it directly interfaces with the 4616101066 TRANSMISSION HOUSING to form the main gearbox shell. The SKU 4616.301.307 is manufactured to ZF’s exacting tolerances, ensuring that all internal shafts and clutches remain perfectly centered under high torque loads.

Symptoms of Failure

• External oil seepage at the bell housing joint: When the housing face warps or cracks, transmission fluid leaks past the gasket, often noticed as drips after parking.
• Erratic gear engagement or delayed shifting: A deformed housing can misalign the valve body, causing pressure loss to clutches and resulting in harsh or slipping shifts.
• Unusual metallic grinding noises: If the bearing bore wears out, gear shafts lose support, leading to contact between rotating parts and a distinct whine or grind.
• Contaminated transmission fluid: Cracks in the housing allow debris ingress, which accelerates wear on internal components like the 0732611049 FILTER INSERT.

Technical Specifications

Compatibility

This housing is specifically designed for the WG 65 series, but it also fits select ZF off-highway transmissions that share the same bolt pattern and hydraulic routing. Compatible models include the WG 65, WG 80, and WG 100 series. For proper assembly, always pair this housing with the 0636011118 HEXAGON SCREW and the 0636011038 HEXAGON SCREW to secure the mating flanges. Additionally, the 4616301309 HOUSING is used as the rear cover on these same transmissions, requiring identical sealing procedures.
