Overview
The ZF 4651.353.027 SPUR GEAR is a precision-engineered component designed for the WG 100 series transmission. This OEM genuine part plays a critical role in transferring rotational force between parallel shafts within the gear train, ensuring smooth power delivery and optimal torque management. Positioned within the intermediate shaft assembly, the spur gear (SKU: 4651.353.027) directly engages with the 4651101006: TRANSMISSION HOUSING to maintain correct gear mesh alignment. Its hardened steel construction resists wear under high-load conditions, making it essential for maintaining transmission efficiency in heavy-duty industrial applications.
Symptoms of Failure
When the ZF 4651.353.027 spur gear deteriorates, operators may notice distinct performance issues. Whining or grinding noises during gear engagement often indicate tooth surface fatigue or pitting. Intermittent gear slipping under load suggests worn tooth profiles that fail to maintain proper contact. Metallic debris in the transmission fluid is a clear sign of spalling or chipping. Vibration during acceleration can occur when uneven wear disrupts the gear’s rotational balance. Early detection of these symptoms prevents secondary damage to the 4651301034: HOUSING and adjacent components.

Compatibility
This spur gear is specifically engineered for the ZF WG 100 series, but its design principles extend to several related transmission models. Primary compatibility includes WG 100, WG 120, and WG 150 gearboxes. It may also fit select WG 180 and WG 200 variants when used in auxiliary drive positions. Always verify tooth count and bore dimensions against your existing gear. The gear interfaces directly with the 0634303928: O-RING for sealing and the 4651301013: HOUSING for structural support. For non-WG series transmissions, consult ZF technical documentation before installation.
