ZF 0730.304.460 WASHER | OEM Genuine Part

Overview

The ZF 0730.304.460 WASHER is a precision-engineered OEM genuine component designed to maintain critical axial clearances within ZF heavy-duty transmission assemblies. This hardened steel washer sits between rotating shafts and stationary housings, acting as a load-spreading interface that prevents metal-on-metal contact. Commonly found in construction machinery drivelines, the SKU 0730.304.460 ensures proper preload on bearings and gear sets, directly influencing torque transfer efficiency. When installed alongside the 2098117002: HOUSING, this washer stabilizes the shaft alignment within the main gear cluster.

Symptoms of Failure

• Transmission oil seepage at housing joints – A worn 0730.304.460 washer can distort under load, creating gaps that allow ATF to escape past the 2098301052: REAR AXLE HOUS. seal surface.
• Intermittent gear slipping under load – When the washer thickness degrades, axial play increases, causing clutch packs to lose engagement pressure during excavation or grading operations.
• Metallic grinding noise from transmission sump – Thinned washers permit shaft-to-housing contact, producing a distinct high-pitched chatter during cold starts or low-speed maneuvering.
• Erratic shift timing in powershift transmissions – Loss of washer integrity alters the preload on the 0636103300: STUD and 0637101164: HEXAGON NUT assembly, confusing hydraulic control pressures.

Technical Specifications

Compatibility

This washer is integral to ZF WG series powershift transmissions used in wheel loaders, dozers, and telehandlers. It directly fits the WG180, WG200, and WG310 models where it secures the output shaft bearing pack. The part also appears in the 4WG-200 and 6WG-310 variants, often paired with the 0636102566: STUD and 0636100960: STUD for housing retention. For brake-side applications, it works with the 2098317013: BRAKE HOUSING and 2098317028: BRAKE HOUSING assemblies.
