Overview
The ZF 4616.308.137 SPUR GEAR is a precision-machined component engineered for the WG 65 Series transmission family. This gear is responsible for transferring rotational force between parallel shafts within the gear train, directly influencing torque delivery and overall driveline efficiency. As an OEM genuine part, SKU 4616.308.137 ensures exact fitment and metallurgical consistency required for heavy-duty industrial applications. When installed alongside the 4616101059 TRANSMISSION HOUSING, this spur gear maintains proper gear mesh alignment and reduces parasitic power loss.
Symptoms of Failure
- Whining or howling noise during acceleration: A worn 4616.308.137 spur gear produces a distinct high-pitched whine that intensifies under load, indicating tooth surface degradation or pitting.
- Vibration in the drivetrain at specific RPM ranges: As gear teeth wear unevenly, harmonic vibrations transmit through the transmission housing, often felt as a shudder in the chassis or shift lever.
- Metallic debris in transmission oil: Flakes or fine silver particles found during oil changes signal advanced wear of the spur gear’s tooth flanks, requiring immediate replacement to prevent cascading damage.
- Intermittent gear slippage under heavy torque: Worn gear profiles fail to maintain positive engagement, causing momentary loss of power transfer during high-load operations.
