ZF 5838.110.025 P.T.O. SHAFT for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 5838.110.025 P.T.O. SHAFT is a critical power take-off drive component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part transmits rotational energy from the transmission’s internal gearing to auxiliary hydraulic pumps or other driven equipment. Positioned within the gear train, it interfaces directly with the 5838109021: DIFFERENTIAL to ensure smooth torque distribution. The SKU 5838.110.025 is precision-machined to ZF’s exacting tolerances, guaranteeing reliable engagement under heavy industrial loads.

Symptoms of Failure

• Intermittent PTO engagement failure: A worn shaft may cause the PTO to disengage unexpectedly during operation, especially under load, leading to lost hydraulic pressure.
• Metallic grinding noise from transmission housing: As the shaft splines wear, they produce a distinct grinding sound when the PTO is activated, often accompanied by vibration.
• Oil seepage near the PTO mounting flange: Deterioration of the shaft’s sealing surface allows transmission fluid to leak, creating visible drips under the vehicle.
• Reduced auxiliary power output: Slippage at the shaft interface results in diminished torque transfer, causing pumps or generators to underperform.

Technical Specifications

Compatibility

This P.T.O. shaft is specifically designed for ZF WG100, WG130, and WG131 transmissions. It is also compatible with the WG180 and WG200 series when used with the correct adapter kit. The shaft works in conjunction with the 0750117075: TAPER ROLLER BEARING to support axial loads, and it mates with the 2095209019: DIFFERENTIAL for final drive integration. A 0631329086: SPRING PIN secures the shaft to the PTO gear hub, preventing rotational play.
