ZF 4644.151.545 COUPLING for WG 180/WG 200 | OEM Genuine Part

Overview

The ZF 4644.151.545 COUPLING is a critical driveline component engineered specifically for the WG 180 and WG 200 transmission series. This OEM genuine part serves as the primary torque-transfer interface between the engine output and the transmission input shaft, ensuring smooth power delivery under heavy industrial loads. The SKU 4644.151.545 is precision-machined to maintain concentric alignment, reducing vibration and wear on adjacent assemblies. When installed alongside the 4644101249: TRANSMISSION HOUSING or the 4644301402: TRANSMISSION HOUSING, this coupling guarantees a sealed, high-torque connection that withstands continuous operation in construction, mining, and material handling equipment.

Symptoms of Failure

• Transmission oil leaks at the bell housing interface: A worn 4644.151.545 coupling can cause misalignment, leading to seal degradation and visible fluid seepage around the housing joint.
• Gear slipping under load during acceleration: When the coupling splines wear, torque transfer becomes intermittent, resulting in hesitation or slipping in forward and reverse gears.
• Abnormal driveline vibration or clunking: Excessive play in the coupling produces a rhythmic knocking sound, especially when shifting between drive and neutral.
• Difficulty engaging the 4644109044: PARKING BRAKE: Coupling wear can affect the parking brake drum alignment, causing binding or incomplete engagement.

Technical Specifications

Compatibility

This coupling is designed for the ZF WG 180 and WG 200 transmission series. It is a direct replacement for units used in ZF WG180, WG200, and select WG210 variants. The 4644.151.545 interfaces with the 4644301298: COVER PLATE and requires a fresh 0634306323: O-RING during installation to prevent fluid bypass. Always verify spline count and pilot bore dimensions against your specific transmission model before ordering.
