Overview
The ZF 4143.216.026 BEVEL GEAR SET is a precision-engineered OEM genuine component designed for the transfer of rotational power at a 90-degree angle within the driveline of ZF WG100, WG130, and WG131 transmissions. This matched set of spiral bevel gears ensures smooth, low-noise torque delivery from the input shaft to the differential or output shaft assembly. As a critical element of the gear train, the SKU 4143.216.026 directly influences the transmission’s load capacity and operational efficiency. When installing this gear set, it is essential to pair it with a new 0501318136: GASKET to ensure a proper seal against the 4143101016: HOUSING and the 4143301039: HOUSING.
Symptoms of Failure
When the bevel gear set wears beyond tolerance, operators will notice distinct performance degradation. Common failure indicators include a whining or howling noise during acceleration or deceleration, particularly in lower gears. Another symptom is gear slipping or jumping under heavy load, which can feel like a momentary loss of drive. You may also observe metallic debris or filings in the transmission fluid during routine changes, a clear sign of pitting or spalling on the gear teeth. Finally, excessive backlash in the driveline can cause a clunking sensation when shifting between forward and reverse. Addressing these issues promptly prevents damage to the 0636101084: CAP SCREW and other mounting hardware.

Compatibility
This bevel gear set is specifically engineered for ZF transmissions in the HL 100 Series and HL 270 Series. It is a direct fit for the WG100, WG130, and WG131 models. While primarily designed for these units, the 4143.216.026 may also be compatible with earlier iterations of the WG180 and WG200 transmissions that share the same drop-box architecture. Always verify the tooth count and backlash specifications against your transmission’s serial number before installation. For proper assembly, ensure the housing bores are clean and inspect the 4143101016: HOUSING for any wear.
