ZF 0730.106.007 THRUST WASHER | OEM Genuine Part

Overview

The ZF 0730.106.007 Thrust Washer is a precision-engineered OEM genuine component designed to manage axial loads and maintain critical clearances within ZF heavy-duty transmission assemblies. Positioned between rotating shafts and stationary housings, this washer prevents metal-on-metal contact, reducing friction and heat buildup. The SKU 0730.106.007 is commonly found in the clutch pack and planetary gear sections of construction machinery transmissions, where it supports the 4143101009 HOUSING and 4143301025 HOUSING during high-torque operation. Its hardened surface ensures long service life under continuous heavy loads.

Symptoms of Failure

• Transmission gear slipping under load: A worn thrust washer allows excessive axial play, causing clutch packs to disengage intermittently during operation.
• Metallic grinding noise from the transmission: As the washer thins, hardened steel surfaces contact directly, producing a distinct grinding sound during gear changes.
• Low hydraulic pressure warnings: Debris from a failing washer can clog oil passages, reducing pressure to clutches and valves.
• Oil contamination with metallic particles: Visible silver or bronze flakes in the transmission fluid indicate the thrust washer is disintegrating.

Technical Specifications

Compatibility

This thrust washer is engineered for ZF WG-series powershift transmissions commonly used in construction machinery. It is a direct fit for the WG180, WG200, and WG210 models, as well as select variants of the WG120 and WG150 series. The part is also compatible with ZF 4WG-200 and 4WG-310 transmissions found in wheel loaders, graders, and dump trucks. Always verify clearance with the 0634313603 O-RING and 4475280018 SCREW PLUG during installation.
