ZF 4108.138.016 FAN | OEM Genuine Part

Overview

The ZF 4108.138.016 FAN is an OEM genuine component engineered for thermal management within heavy-duty construction machinery transmissions. This critical part mounts directly onto the transmission housing assembly, drawing air across the oil cooler and transmission casing to maintain optimal operating temperatures under extreme loads. As a factory-specified cooling fan, the SKU 4108.138.016 ensures consistent airflow to prevent fluid degradation and component overheating during prolonged operation in demanding environments like excavators, wheel loaders, and graders.

Symptoms of Failure

When the ZF 4108.138.016 FAN begins to wear, operators often notice distinct performance issues. Insufficient cooling capacity is a primary symptom, leading to transmission fluid temperatures exceeding normal ranges during heavy use. Abnormal vibration or wobbling from the fan assembly indicates blade imbalance or hub fatigue, which can accelerate bearing wear. Reduced airflow noise or a high-pitched whine suggests the fan is not spinning at the required RPM. Additionally, intermittent overheating during low-speed operation points directly to a failing fan that cannot maintain adequate air movement.

Technical Specifications

Compatibility

This genuine ZF fan is primarily used in the WG180 and WG200 series transmissions, commonly found in construction machinery from manufacturers such as Case, New Holland, and Liebherr. It also fits select WG150 and WG210 models where the cooling package shares the same mounting pattern. Always verify the fan hub pilot diameter and bolt pattern against your existing assembly before installation.
