ZF 0730.002.728 WASHER | OEM Genuine Part

Overview

The ZF 0730.002.728 WASHER is a precision-engineered OEM genuine component designed to maintain critical axial clearances within ZF heavy-duty construction machinery transmissions. This hardened steel washer sits between the transmission housing and rotating shaft assemblies, preventing metal-on-metal contact and ensuring proper preload on bearings. The SKU 0730.002.728 is specifically manufactured to ZF’s exacting tolerances, making it essential for rebuilds of gearboxes used in wheel loaders, graders, and dump trucks. When installed alongside the 2094101012: TRANSMISSION HOUSING, this washer forms a vital part of the load-bearing structure that absorbs axial thrust forces during operation.

Symptoms of Failure

• Transmission oil leaks at housing mating surfaces – A worn 0730.002.728 washer allows excessive shaft play, which can distort the 2094301036: HOUSING seal area, leading to fluid seepage around the output flange.
• Gear engagement hesitation or slipping – When this washer loses its thickness, axial clearance increases, causing shift forks to misalign and clutches to drag, resulting in delayed gear changes under load.
• Metallic grinding noise during deceleration – A collapsed washer permits the shaft to contact the 2094298057: HOUSING interior, producing a distinct grinding sound that worsens as the transmission warms up.
• Vibration through the driveline – Uneven washer wear creates imbalance in the planetary gear set, transmitting noticeable shudder through the chassis at highway speeds.

Technical Specifications

Compatibility

This washer is a standard component in ZF’s WG180, WG200, and WG210 series transmissions, commonly found in construction machinery from Volvo, Caterpillar, and Liebherr. It also fits select ZF 4WG-200 and 6WG-200 models used in telescopic handlers and road rollers. Always verify the part number against your transmission’s parts manual; the 0730.002.728 is frequently used in conjunction with the 2094301071: COVER to seal the bearing cavity.
