Overview
The ZF 4143.316.086 PINION is a critical gear component engineered for the power take-off (PTO) drive assembly within the WG100, WG130, and WG131 transmission series. This OEM genuine part transfers rotational force from the transmission’s internal gearing to the output shaft, ensuring precise torque delivery for auxiliary hydraulic systems. As a hardened steel pinion, it interfaces directly with the 4143101030 HOUSING to maintain gear alignment and reduce backlash. The SKU 4143.316.086 is manufactured to ZF’s original tolerances, guaranteeing a direct fit without modification. This pinion is also integral to the HL 100 Series and HL 270 Series categories, where it supports heavy-duty industrial applications requiring consistent rotational accuracy.
Symptoms of Failure
When the ZF 4143.316.086 PINION wears out, operators may notice distinct performance issues. 1. Intermittent PTO engagement failure occurs as worn teeth fail to mesh properly, causing the auxiliary system to disengage under load. 2. Metallic grinding noise from the transmission housing signals advanced tooth wear or pitting, often accompanied by vibration in the driveline. 3. Reduced hydraulic pump output results from the pinion slipping against the 4143301055 HOUSING, leading to sluggish implement operation. 4. Contaminated transmission fluid with metal particles indicates the pinion surface is degrading, which can accelerate wear on the 4143298040 CASE and adjacent bearings. Early replacement of the 4143.316.086 prevents catastrophic gear train failure.

Compatibility
This pinion is designed for ZF WG-series transmissions, specifically the WG100, WG130, and WG131 models. It also fits the HL 100 Series and HL 270 Series industrial transmissions. Based on its PTO drive role, the 4143.316.086 is compatible with the WG180 and WG200 variants when used in auxiliary power configurations. For proper installation, the pinion must be paired with the 0631329135 SPRING PIN to secure it to the output shaft. Always verify the transmission serial number against ZF’s parts catalog to confirm fitment for WG180 or WG200 units.
