ZF 5838.110.020 P.T.O. SHAFT for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 5838.110.020 P.T.O. SHAFT is a critical power take-off shaft engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine component transfers rotational energy from the transmission gear train to auxiliary hydraulic pumps or driven equipment. Positioned within the PTO housing assembly, the shaft interfaces directly with the 5838109021: DIFFERENTIAL to ensure smooth torque delivery. The SKU 5838.110.020 is precision-machined to ZF factory tolerances, guaranteeing exact fitment and long service life in heavy-duty industrial applications.

Symptoms of Failure

• PTO gear slipping under load: Worn splines on the 5838.110.020 shaft cause intermittent engagement, leading to power loss during operation.
• Excessive driveline vibration: A bent or fatigued shaft creates harmonic imbalance, often accompanied by a rhythmic knocking sound from the PTO housing.
• Hydraulic pump failure to engage: When the shaft’s pilot bearing surface wears, the PTO clutch cannot fully seat, preventing auxiliary equipment activation.
• Oil leaks at the PTO housing seal: Grooves worn into the shaft’s sealing surface allow transmission fluid to escape, visible as drips beneath the vehicle.

Technical Specifications

Compatibility

This P.T.O. shaft is designed exclusively for ZF WG-series powershift transmissions. Verified compatible models include: WG100, WG130, WG131, WG180, and WG200. It also fits select WG121 and WG150 variants when used with the correct 0631329086: SPRING PIN for retention. For differential-side applications, pair this shaft with the 2095209019: DIFFERENTIAL assembly. Always verify housing clearance when retrofitting into non-standard PTO configurations.

During installation, the 0750117075: TAPER ROLLER BEARING must be pressed onto the shaft’s shoulder to support axial loads. Inspect the mating thrust washers and sealing rings for wear before reassembly.
