Overview
The ZF 4143.216.046 BEVEL GEAR SET is a precision-engineered component designed for the transfer of torque and rotational speed within the auxiliary drive and power take-off (PTO) sections of ZF WG100, WG130, and WG131 transmissions. This OEM genuine part ensures the correct meshing of gears to deliver smooth, reliable power distribution to secondary systems. The SKU 4143.216.046 is a matched set, meaning both the drive and driven bevel gears are manufactured as a pair to guarantee optimal tooth contact and minimal noise. This set sits directly within the gear housing assembly and is critical for maintaining the mechanical integrity of the drivetrain.
Symptoms of Failure
- Whining or howling noise during PTO engagement: A high-pitched metallic sound when the power take-off is activated often indicates worn or incorrectly meshed bevel gear teeth.
- Vibration in the transmission housing: Excessive play in the bevel gear set can cause noticeable vibration, particularly at specific RPM ranges, which may be felt through the chassis.
- Metal particles in the transmission oil: Flaking or pitting on the gear teeth surfaces will shed metallic debris into the lubricant, visible during an oil change or filter inspection.
- Intermittent power loss to auxiliary equipment: If the gear set begins to skip or slip under load, the driven equipment (such as a hydraulic pump) may experience inconsistent power delivery.

Compatibility
This bevel gear set is specifically engineered for the ZF WG100, WG130, and WG131 transmission series. While these are the primary applications, the gear geometry may also be compatible with certain variants of the WG180 and WG200 series that utilize the same auxiliary drive housing. Always verify the tooth count and shaft diameter against your existing set before installation. For transmissions requiring a complete rebuild, this set is often paired with a new 4143101016: HOUSING and a 4143301039: HOUSING to ensure proper alignment.
During installation, it is mandatory to replace the 0501318136: GASKET to prevent oil seepage. The assembly is secured using 0636101084: CAP SCREW fasteners, which must be torqued to factory specifications. Failure to replace these sealing and fastening components can lead to premature wear of the new gear set.
