ZF 4699.372.045 WASHER | OEM Genuine Part

Overview

The ZF 4699.372.045 WASHER is a precision-engineered OEM genuine component designed to maintain critical axial clearances within ZF construction machinery transmissions. This hardened steel washer functions as a load-spreading interface between rotating shafts and stationary housings, preventing metal-on-metal contact that leads to premature gear wear. As part of the transmission’s internal shimming system, the SKU 4699.372.045 ensures proper preload on bearings and planetary gear sets, directly influencing torque transfer efficiency. It is typically installed during transmission rebuilds or when replacing adjacent components like the 4699101045 HOUSING or the 4699301108 HOUSING.

Symptoms of Failure

• Transmission oil seepage at housing joints – A worn 4699.372.045 washer can distort, creating gaps that allow hydraulic fluid to escape past the 4699301085 COVER.
• Gear slipping under load – Thinning of the washer reduces axial preload, causing planetary gear sets to lose engagement during heavy excavation or lifting operations.
• Metallic grinding noise from the transmission – When the washer fails completely, hardened steel fragments contaminate the oil, leading to scoring on shafts and the 4699301014 THREAD PROTECTIVE SHIELD.
• Increased backlash in driveline – Excessive axial play from a collapsed washer results in delayed power delivery when shifting between forward and reverse.

Technical Specifications

Compatibility

This washer is engineered for ZF WG-series powershift transmissions commonly found in wheel loaders, dozers, and excavators. It is a direct fit for the following models: WG180, WG200, WG210, and WG250. The 4699.372.045 also appears in certain ZF Ergopower and Ecolife transmissions used in agricultural tractors and material handlers. Always verify the washer thickness against your transmission’s service manual, as shimming requirements vary by application.
