ZF 0730.111.751 WASHER for WG200 | OEM Genuine Part

Overview

The ZF 0730.111.751 WASHER is a precision-engineered OEM genuine component designed for the WG 200 series transmissions. This hardened steel washer functions as a critical load-spreading element between the 4460115043 HOUSING and the rotating shaft assembly, ensuring proper axial clearance and preventing metal-on-metal contact under high torque loads. As part of the planetary gear set retention system, the SKU 0730.111.751 maintains exacting tolerances to preserve gear mesh alignment and oil film integrity within the transmission’s lubrication circuit.

Symptoms of Failure

• Transmission oil seepage at housing joints: A worn 0730.111.751 washer can cause misalignment, leading to compromised sealing between the 4469315012 AXLE DRIVE HOUSING and the main casing, resulting in visible fluid loss.
• Abnormal gear whine or grinding during load shifts: When this washer loses its original thickness, axial play increases, allowing the 0750117406 TAPER ROLLER BEARING to shift, creating irregular contact patterns and audible distress.
• Erratic clutch engagement or delayed shifting: Excessive clearance from a collapsed washer alters the preload on the 0750117802 TAPERED ROLLER BEARING, causing hydraulic pressure fluctuations in the valve body.
• Vibration through the driveline at highway speeds: A fatigued washer fails to maintain concentricity, leading to rotational imbalance that transmits through the output shaft.

Technical Specifications

Compatibility

This washer is primarily specified for the ZF WG 200 series transmissions, including the WG200, WG210, and WG220 variants used in medium-duty trucks and construction equipment. It also fits select WG180 models where the planetary carrier assembly shares the same shaft diameter. For applications requiring alternative thicknesses, consider the 0730161317 WASHER (2.0 mm) or 0730161451 WASHER (3.0 mm). Always verify stack height using the 0730161340 WASHER as a reference shim.
