ZF 4651.252.007 SPUR GEAR for WG100 | OEM Genuine Part

Overview

The ZF 4651.252.007 SPUR GEAR is a precision-engineered component designed for the WG 100 series transmission. This gear sits within the planetary gearset assembly, where it transmits torque and rotational motion between the input shaft and the output drive. As an OEM genuine part, the SKU 4651.252.007 ensures exact fitment and metallurgical integrity, reducing backlash and maintaining the gear train’s efficiency under heavy-duty loads. It works in concert with the 4651101005: TRANSMISSION HOUSING to align the shaft centers and with the 4651301010: HOUSING to protect the gear from debris ingress.

Symptoms of Failure

When the ZF 4651.252.007 spur gear wears out, operators may notice distinct failure indicators. Whining or grinding noise during gear engagement is a common early sign, often caused by pitting or chipped teeth. Intermittent gear slipping under load occurs when the gear’s tooth profile degrades, reducing torque transfer capability. Metal particles in the transmission oil filter signal advanced wear, as the gear sheds material into the lubricant. Vibration at specific RPM ranges indicates uneven tooth contact, which can accelerate damage to the 0634303928: O-RING seals and the 4651301017: HOUSING.

Technical Specifications

Compatibility

This spur gear is primarily designed for the ZF WG 100 series, but it also fits select models in the WG 180 and WG 200 families due to shared gear train architecture. It is compatible with WG 100, WG 101, WG 102, WG 180, and WG 200 transmissions manufactured after 2005. Always verify the gear’s tooth count and shaft bore diameter against your transmission’s service manual. The gear interfaces directly with the 4651101005: TRANSMISSION HOUSING and the 4651301010: HOUSING to maintain proper alignment.
