Overview
The ZF 4616.306.114 Intermediate Plate is a precision-machined structural component engineered for the WG 65 series of heavy-duty transmissions. Positioned between the main transmission housing and the output assembly, this OEM genuine part acts as a critical separator and alignment guide for internal gear sets and hydraulic circuits. The SKU 4616.306.114 ensures exact fitment and oil flow integrity within the WG65 gear train, preventing cross-contamination between lubrication channels. When paired with a new 4616105415 OUTPUT and 4616303144 OUTPUT FLANGE, this plate restores factory-spec torque transfer and sealing performance.
Symptoms of Failure
- Oil leaks at the intermediate housing seam: A warped or cracked plate causes fluid to weep between the 4616101094 TRANSMISSION HOUSING and the output section, visible as drips under the bell housing.
- Gear slipping under load: Worn locating surfaces allow the intermediate shaft to shift, leading to intermittent power loss during acceleration or hill climbs.
- Metallic debris in transmission fluid: Fretting corrosion on the plate’s mating faces generates fine steel particles that contaminate the oil, often detected during routine filter changes.
- Abnormal vibration from the driveline: Misalignment caused by a distorted plate creates harmonic vibrations that intensify at highway speeds.

Compatibility
This intermediate plate is specifically designed for the ZF WG 65 series, which includes models such as WG65, WG80, WG100, WG120, WG150, WG180, and WG200. It is also compatible with certain off-highway variants (WG65-2, WG65-3) used in construction and agricultural equipment. Always verify the transmission serial number before ordering. For complete assembly, use a new 0636011038 HEXAGON SCREW to secure the plate to the housing.
