Overview
The ZF 4616.308.147 GEAR is a precision-machined component engineered specifically for the WG65 series of heavy-duty transmissions. This OEM genuine part functions as a critical torque-transfer element within the planetary gear set, directly influencing gear ratio stability and load distribution. Located in the intermediate shaft assembly, the 4616.308.147 gear meshes with adjacent components to ensure smooth power delivery under high-stress conditions. When paired with a robust 4616105413: OUTPUT shaft, this gear maintains alignment and reduces vibrational wear. The SKU 4616.308.147 is manufactured to ZF’s original specifications, guaranteeing interchangeability with factory-installed units.
Symptoms of Failure
- Whining or grinding noise during gear engagement: Worn gear teeth produce a distinct metallic sound, especially under load, indicating surface fatigue or pitting on the 4616.308.147 gear.
- Intermittent gear slipping under acceleration: A failing gear loses tooth profile integrity, causing momentary loss of torque transfer, often misdiagnosed as clutch issues.
- Metal particles in transmission fluid: Flaking or chipping of the gear surface introduces ferrous debris into the oil, detectable during routine filter inspections.
- Hard shifting between forward and reverse: Excessive backlash from a worn 4616.308.147 gear disrupts synchronizer timing, leading to delayed or harsh engagement.

Compatibility
This gear is a direct fit for the ZF WG65 series, which includes models such as WG65, WG70, and WG80. It is also compatible with select WG180 and WG200 variants that share the same planetary gear architecture, though verification of the output flange interface is recommended. The 4616.308.147 gear integrates with the 4616203017: OUTPUT FLANGE to secure rotational alignment, and it seats within the 4616101117: TRANSMISSION HOUSING using 0636011038: HEXAGON SCREW fasteners. Always cross-reference your transmission serial number with ZF’s parts catalog before ordering.
