ZF 0730.006.902 WASHER | OEM Genuine Part

Overview

The ZF 0730.006.902 WASHER is an OEM genuine shim component engineered for precise axial clearance control within heavy-duty construction machinery transmissions. This hardened steel washer sits between the differential housing and the planetary gear set, maintaining critical end-play tolerances that prevent gear train binding. As part number 0730.006.902, it functions as a load-bearing spacer that absorbs thrust loads during high-torque operations. When replacing this washer, technicians often inspect the adjacent 5838109007: DIFFERENTIAL assembly for wear patterns, as both components share the same lubrication circuit.

Symptoms of Failure

• Transmission oil seepage at the differential housing: A worn 0730.006.902 washer allows excessive axial movement, breaking the seal between the housing and output shaft, leading to visible fluid leaks.
• Intermittent gear slipping under load: When the washer thickness degrades, the 0750117075: TAPER ROLLER BEARING loses preload, causing momentary torque loss during excavation or grading.
• Metallic grinding noise during deceleration: Failed washers permit metal-on-metal contact between the differential case and planetary carrier, producing a distinct scraping sound.
• Vibration in the driveline at low RPM: Uneven washer wear creates imbalance in the rotating assembly, felt as a low-frequency shudder through the chassis.

Technical Specifications

Compatibility

This washer is primarily specified for ZF WG180, WG200, and WG210 series powershift transmissions used in wheel loaders, graders, and excavators. It also appears in select ZF 4WG-200 and 6WG-200 drivelines where the 2095209019: DIFFERENTIAL assembly requires precise shimming. For models with integrated parking brakes, verify clearance using the 0631329086: SPRING PIN alignment tool during installation.
