ZF 4616.307.005 CONNECTING PART for WG65 | OEM Genuine Part

Overview

The ZF 4616.307.005 CONNECTING PART is a critical structural link within the WG 65 Series transmission assembly. This OEM genuine component serves as the intermediary bridge between the main transmission housing and the auxiliary gear group, ensuring precise alignment and torque transfer under heavy-duty loads. Designed exclusively for ZF’s WG series, the SKU 4616.307.005 maintains the rigid geometry required for smooth power distribution in off-highway and industrial drivetrains. When installed alongside the 4616101059 TRANSMISSION HOUSING, this connecting part prevents axial misalignment that can lead to premature gear wear.

Symptoms of Failure

• Transmission housing oil leaks at the joint interface – Worn connecting parts allow fluid to escape between the main case and auxiliary section, often visible as drips near the bell housing.
• Gear slipping under load in WG65 transmissions – Degraded alignment causes intermittent disengagement between gear sets, producing a grinding sensation during acceleration.
• Abnormal vibration at the driveline connection – A loose connecting part transmits harmonic oscillations through the chassis, especially noticeable at 40-60 km/h.
• Difficulty engaging reverse gear – Misalignment stresses the shift mechanism, requiring excessive force to select reverse on WG65 models.

Technical Specifications

Compatibility

This connecting part is engineered for the ZF WG 65 Series, including the WG65, WG120, WG180, and WG200 transmission models. It is also compatible with select WG250 variants produced after 2012. Always verify fitment by cross-referencing the 4616.307.005 with your transmission’s serial number. For proper installation, pair this component with the 0631306085 CYLINDRICAL PIN for alignment and the 0634313118 O-RING to seal the joint.
