ZF 0730.002.745 WASHER | OEM Genuine Part

Overview

The ZF 0730.002.745 WASHER is an OEM genuine precision shim engineered for critical axial clearance control within ZF heavy-duty construction machinery transmissions. This hardened steel washer sits between the planetary gear set and the 2094101012: TRANSMISSION HOUSING, ensuring correct end-play tolerances for the rotating assembly. As a load-bearing component, the SKU 0730.002.745 prevents metal-to-metal contact between the gear train and the housing, directly influencing torque transfer efficiency and overall transmission lifespan. Its exact thickness is calibrated to maintain proper preload on bearings and clutches during high-torque operations in wheel loaders, graders, and dozers.

Symptoms of Failure

• Transmission oil leaks at housing seam: A worn or crushed 0730.002.745 washer allows the gear assembly to shift, distorting the seal surface against the 2094301036: HOUSING, leading to external fluid seepage.
• Gear slipping under load: When this washer loses its original thickness, axial play increases, causing clutch packs to disengage momentarily during heavy digging or pushing operations.
• Metallic grinding noise from transmission: Excessive clearance from a failed washer permits the planetary gears to contact the 2094298057: HOUSING, producing a distinct grinding sound during shifts.
• Erratic shift timing: Worn axial clearance alters hydraulic pressure distribution, causing delayed or harsh engagement between forward and reverse gears.

Technical Specifications

Compatibility

This washer is specifically designed for ZF WG series powershift transmissions commonly used in construction machinery. It is a direct fit for the WG180, WG200, and WG211 transmission models. The 0730.002.745 also appears in the WG150 and WG310 series where planetary gear end-play adjustment is required. Always verify the stack height when replacing this washer alongside the 2094301071: COVER to ensure proper preload restoration.
