ZF 4108.102.069 INPUT | OEM Genuine Part

Overview

The ZF 4108.102.069 INPUT is a critical OEM genuine component designed to transfer engine torque directly into the transmission assembly. Positioned at the front of the gearbox, this input unit interfaces with the clutch or torque converter, ensuring smooth power delivery to the planetary gears. As a factory-spec replacement, the SKU 4108.102.069 guarantees precise fitment and durability under heavy loads, making it essential for maintaining operational efficiency in construction machinery. When paired with a robust 4108101165: HOUSING, this part forms the primary structural seal against contaminants and vibration.

Symptoms of Failure

• Transmission slipping under load: Worn input splines or bearing surfaces cause intermittent power loss, especially during uphill or heavy digging operations.
• Oil seepage at the bell housing: Degraded sealing surfaces allow hydraulic fluid to escape, often visible as drips near the engine-transmission junction.
• Grinding noise during engagement: Damaged gear teeth or a misaligned input shaft produce a metallic chatter when shifting from neutral to drive.
• Vibration at idle: Excessive play in the input assembly transmits harmonic tremors through the chassis, worsening with RPM changes.

Technical Specifications

Compatibility

This input component is engineered for ZF WG-series powershift transmissions commonly used in wheel loaders, excavators, and telehandlers. It directly fits the WG180, WG200, and WG210 models. For proper sealing, always replace the 0636302015: SCREW PLUG and 0501325471: SEALING RING during installation. The 0730365280: TYPE PLATE should also be verified for correct model identification. Additional compatible transmissions include the WG150 and WG240, though spline dimensions should be cross-referenced.
