ZF 4624.307.006 COVER for WG65 | OEM Genuine Part

Overview

The ZF 4624.307.006 COVER is a precision-engineered OEM genuine component designed specifically for the WG 65 Series transmission family. This cover serves as a critical sealing and protective barrier, typically mounted on the transmission housing to safeguard internal hydraulic and mechanical assemblies from contamination and pressure loss. The SKU 4624.307.006 ensures a factory-spec fitment, working in concert with the TRANSMISSION HOUSING to maintain structural integrity. When installed alongside the OUTPUT assembly and the OUTPUT FLANGE, this cover prevents lubricant migration and debris ingress, directly influencing shift quality and long-term durability.

Symptoms of Failure

• External oil seepage around the cover perimeter: A worn or cracked 4624.307.006 cover often manifests as slow, persistent transmission fluid leaks near the rear housing, especially after thermal cycling.
• Contaminated transmission fluid: When the cover loses its seal, dirt and moisture enter the system, leading to gritty or discolored oil that accelerates internal wear.
• Abnormal gear engagement noise: A compromised cover can allow slight misalignment of the output shaft assembly, producing a low hum or clatter during gear changes under load.
• Intermittent pressure drops: Hydraulic circuit instability, particularly in reverse or low gears, may trace back to a failing cover that no longer maintains consistent backpressure within the valve body area.

Technical Specifications

Compatibility

This cover is engineered for the ZF WG 65 Series, which includes the WG180, WG200, and WG250 transmission models commonly found in heavy-duty construction and agricultural machinery. It directly interfaces with the OUTPUT shaft assembly and the OUTPUT FLANGE. For proper installation, always pair with a new HEXAGON SCREW set to ensure even clamping force. The cover is not backward-compatible with earlier WG 50 series housings without adapter modifications.
