Overview
The ZF 6053.108.407 CONTROL COVER is a precision-machined OEM genuine component that seals and protects the hydraulic control valve assembly within ZF heavy-duty powershift transmissions. This cover, identified by SKU 6053.108.407, sits atop the transmission housing, directly over the valve body, ensuring proper oil flow direction and pressure regulation. It acts as a critical barrier against contamination while maintaining the structural integrity of the shift control system. In construction machinery applications, this part is essential for consistent gear engagement and smooth power delivery under extreme loads.
Symptoms of Failure
- External oil seepage around the valve body area: A worn or warped ZF 6053.108.407 CONTROL COVER often leads to visible hydraulic fluid leaks, especially during high-pressure operation. This is a common long-tail search query for “ZF transmission control cover oil leak repair.”
- Erratic or delayed gear engagement: When the cover loses its sealing capability, air ingress disrupts hydraulic pressure, causing “ZF transmission slipping when hot” or “delayed shifting in WG series transmissions.”
- Contaminated transmission fluid: A cracked or damaged cover allows dirt and debris to enter the valve body, leading to “transmission valve body contamination symptoms” and accelerated wear on internal components.
- Reduced hydraulic pressure at the clutch packs: Internal cracks in the cover can cause pressure loss, resulting in “ZF powershift transmission weak forward drive” or “loss of reverse gear in construction equipment.”

Compatibility
This ZF 6053.108.407 CONTROL COVER is designed for use in the following ZF transmission models commonly found in construction machinery: WG180, WG200, WG211, and WG250 series. It is also compatible with certain variants of the 4WG-200 and 5WG-250 powershift transmissions used in wheel loaders, graders, and telehandlers. Always verify the casting number on your existing cover before installation.
During replacement, it is standard practice to inspect and replace the 4108101057 HOUSING if cracked, and the 4108201177 HOUSING for proper alignment. The 0636302056 SCREW PLUG should be torqued to specification to prevent leaks, and the 4108301304 BEARING COVER must be checked for wear at the output shaft interface.
