ZF 4108.020.013 PLM 7 | OEM Genuine Part

Overview

The ZF 4108.020.013 PLM 7 is a genuine OEM part engineered for the planetary gear set within heavy-duty ZF transmissions used in construction machinery. This component functions as a critical load-bearing element, ensuring precise torque distribution and smooth gear engagement under extreme operational stress. The SKU 4108.020.013 is specifically designed to interface with the transmission’s hydraulic control unit and the main drive shaft assembly. When installed alongside the 4108101150 HOUSING, it forms a sealed chamber that protects internal gears from contamination while maintaining proper lubrication flow. This part is manufactured to ZF’s original tolerances, guaranteeing a direct fit without modification.

Symptoms of Failure

• Delayed gear engagement or slipping under load: Worn internal splines or bearing surfaces on the 4108.020.013 cause inconsistent power transfer, especially during uphill operation or when lifting heavy loads.
• Metallic grinding noise from the transmission housing: Degraded planetary gear teeth produce a distinct whining or grinding sound that intensifies with vehicle speed, often misdiagnosed as a failing 0501211694 MOTOR.
• Hydraulic fluid contamination with metal particles: As the part wears, microscopic shavings enter the oil circuit, clogging filters and accelerating wear on the 0501314793 COVER seal surfaces.
• Intermittent loss of drive in forward gears: A failing PLM 7 assembly can cause sudden neutral conditions, particularly when the transmission reaches operating temperature above 90°C.

Technical Specifications

Compatibility

This genuine ZF 4108.020.013 PLM 7 is compatible with the following transmission models commonly found in wheel loaders, excavators, and telehandlers:

• ZF WG180 (all variants including WG180/2 and WG180/3)
• ZF WG200 (series 200 and 200/2)
• ZF WG210 (early production models)
• ZF 4WG-180 and 4WG-200 powershift transmissions

For proper installation, always replace the 0501314799 BUSH simultaneously to prevent premature wear on the new PLM 7 gear set.
