ZF 5838.300.106 INPUT SHAFT for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 5838.300.106 INPUT SHAFT is a critical torque-transfer component engineered for the WG100, WG130, and WG131 series transmissions. Positioned at the front of the gearbox, this OEM genuine part receives rotational force directly from the engine clutch or torque converter and transmits it into the transmission’s planetary gear sets. The SKU 5838.300.106 is precision-machined to maintain concentricity and spline engagement, ensuring smooth power delivery under heavy loads. When this shaft wears, it directly impacts the alignment of the 5838109006: DIFFERENTIAL and the 2095209037: DIFFERENTIAL assembly, making it a cornerstone of driveline reliability.

Symptoms of Failure

• Hard shifting or gear slipping: A worn input shaft spline can cause intermittent engagement, leading to delayed or rough gear changes under acceleration.
• Oil leaks at the front seal area: Excessive radial play from a damaged shaft wears out the seal, resulting in visible transmission fluid drips near the bell housing.
• Vibration during power take-off (PTO) operation: A bent or fatigued shaft creates harmonic imbalance, felt as a low-frequency shudder when the transmission is under load.
• Metallic debris in the oil pan: Flaking or spalling on the shaft’s bearing journals produces fine metal particles, often found during routine fluid changes.

Technical Specifications

Compatibility

This input shaft is specifically designed for ZF WG-series transmissions, including the WG100, WG130, and WG131 models. It is also compatible with certain WG180 and WG200 variants that share the same front housing geometry. For proper installation, always pair this shaft with a new 0750117075: TAPER ROLLER BEARING to maintain preload tolerances. Additionally, verify the condition of the 2095309059: DIFF.HOUSING to ensure the shaft’s pilot bearing has a secure seat.
