ZF 4642.152.501 COUPLING for WG 150 | OEM Genuine Part

Overview

The ZF 4642.152.501 COUPLING is a critical torque-transfer component engineered specifically for the WG 150 Series transmission. This OEM genuine part sits between the transmission housing and the output shaft assembly, ensuring precise rotational alignment and dampening torsional vibrations during gear shifts. As a direct-fit replacement, the SKU 4642.152.501 guarantees factory-specified clearance and load capacity, making it indispensable for maintaining driveline integrity in heavy-duty industrial applications. When installed alongside the 4642101109: TRANSMISSION HOUSING and the 4642301205: TRANSMISSION HOUSING, this coupling forms a sealed, high-torque interface that withstands continuous operation under extreme loads.

Symptoms of Failure

• Oil seepage at the coupling housing interface: Worn seals or cracked coupling flanges allow transmission fluid to escape, leaving visible drips beneath the vehicle. This is a common long-tail search query for “ZF WG150 coupling oil leak repair.”
• Audible clunking during gear engagement: Excessive play in the coupling splines produces a metallic knock when shifting from neutral to drive or reverse, often described as “ZF transmission clunking noise.”
• Vibration at highway speeds: A degraded coupling fails to dampen driveline harmonics, causing seat-of-the-pants vibration that intensifies above 45 mph—a symptom frequently searched as “ZF WG150 vibration under load.”
• Intermittent gear slippage under torque: When the coupling loses its press-fit tolerance, the transmission may momentarily lose power transfer during uphill climbs or heavy hauling, triggering “ZF transmission slipping when hot” queries.

Technical Specifications

Compatibility

This coupling is primarily designed for the ZF WG 150 Series transmission, but its mounting pattern and spline count also make it compatible with the WG 180 and WG 200 models when used with the correct 0730365125: TYPE PLATE for identification. It is not recommended for WG 250 or higher series without verifying the 0631311009: GROOVED STUD alignment. For exact fitment, always cross-reference the transmission serial number against the coupling’s spline count and pilot bore depth.
