ZF 0730.002.736 WASHER | OEM Genuine Part

Overview

The ZF 0730.002.736 WASHER is an OEM genuine precision shim engineered to maintain critical axial clearances within ZF heavy-duty transmission assemblies. This hardened steel washer sits between the transmission housing and planetary gear sets, ensuring correct preload on bearings and shafts. As a load-distributing component, the SKU 0730.002.736 prevents metal-to-metal contact during high-torque operation, directly influencing gear alignment and clutch pack engagement. When paired with a TRANSMISSION HOUSING or a HOUSING, this washer compensates for thermal expansion and manufacturing tolerances, preserving the transmission’s internal geometry under extreme loads.

Symptoms of Failure

• Oil leaks around the transmission housing interface: A worn 0730.002.736 washer allows axial play, distorting the seal surface against the HOUSING and causing pressurized fluid to escape.
• Gear slipping under load: Insufficient washer thickness reduces clutch pack clamping force, leading to intermittent power loss during acceleration or uphill operation.
• Metallic grinding noise from the planetary section: Failed washers permit gear tooth interference, producing a distinct whine or chatter that worsens as the transmission heats up.
• Premature bearing failure: Without proper shimming from the 0730.002.736, tapered roller bearings experience uneven wear, detectable through vibration analysis or increased end-play.

Technical Specifications

Compatibility

This washer is designed for ZF WG180, WG200, and WG210 series powershift transmissions commonly used in construction machinery like wheel loaders, graders, and telehandlers. It also fits select ZF Ecolife and Ecomat models where axial shimming of the sun gear shaft is required. Always verify the part against the COVER assembly drawing to confirm stack-up tolerances.
