ZF 0899.316.845 COVER | OEM Genuine Part

Overview

The ZF 0899.316.845 COVER is a critical sealing component engineered for heavy-duty construction machinery transmissions. Positioned on the exterior of the transmission housing, this OEM genuine part protects internal gear assemblies from contaminants while maintaining proper oil pressure. As a structural cover, it interfaces directly with the TRANSMISSION HOUSING and adjacent HOUSING components to create a sealed environment for rotating elements. The SKU 0899.316.845 is precision-machined to ZF’s exacting tolerances, ensuring a leak-free interface that supports optimal transmission performance in excavators, loaders, and graders.

Symptoms of Failure

• Oil seepage around the cover perimeter: When the 0899.316.845 cover warps or its sealing surface degrades, transmission fluid escapes, leaving visible wet spots on the housing exterior.
• Contaminant ingress causing gear wear: A compromised cover allows dirt and moisture to enter the transmission, accelerating wear on bearings and gears—often first noticed as whining noises during operation.
• Reduced hydraulic pressure: Cracks or deformation in the cover disrupts internal oil flow, leading to sluggish gear engagement or delayed clutch pack response in ZF WG-series transmissions.
• Vibration at the mounting points: Loose or fatigued cover bolts (often linked to the HEXAGON SCREW fasteners) cause audible rattling and uneven load distribution across the assembly.

Technical Specifications

Compatibility

This cover is designed for ZF’s WG series powershift transmissions commonly found in construction machinery. It directly fits the WG180, WG200, and WG210 models used in wheel loaders and telehandlers. The 0899.316.845 cover also mounts to the HOUSING variant used in WG160 applications, though verification of bolt pattern alignment is recommended. For complete assembly, pair this cover with the COVER gasket (part 2094301030) and a new SHAFT SEAL to prevent premature failure.
