ZF 0730.200.251 THRUST WASHER | OEM Genuine Part

Overview

The ZF 0730.200.251 THRUST WASHER is a precision-engineered OEM genuine component designed to manage axial loads and maintain critical clearances within heavy-duty ZF transmissions. Positioned between rotating gear sets and stationary housings, this thrust washer prevents metal-on-metal contact, ensuring smooth power flow in construction machinery drivetrains. The SKU 0730.200.251 is a direct replacement part that meets original factory tolerances, reducing friction and heat buildup during high-torque operations. This washer is often serviced alongside the 5838109007 DIFFERENTIAL assembly to restore proper gear alignment and extend transmission service life.

Symptoms of Failure

When the ZF 0730.200.251 thrust washer wears beyond specification, operators will notice distinct performance issues. Look for these failure indicators to catch problems early:

• Transmission gear slipping under load — Worn washers allow excessive axial play, causing gears to disengage during heavy lifting or grading operations.
• Metallic grinding noise from the differential area — Thinned thrust washers permit gear teeth to contact housing surfaces, producing a distinct scraping sound at low speeds.
• Oil contamination with bronze or steel particles — As the washer surface degrades, debris enters the lubrication system, often visible during oil changes or filter inspections.
• Intermittent driveline vibration — Uneven washer wear creates axial runout, transmitting vibration through the 0750117075 TAPER ROLLER BEARING and into the chassis.

Technical Specifications

Compatibility

This thrust washer is engineered for ZF heavy-duty powershift transmissions commonly found in wheel loaders, dozers, and graders. It is a direct fit for the WG180, WG200, and WG210 series, as well as select 4WG-200 and 6WG-200 variants. Always verify the washer thickness against your existing part, as these transmissions use multiple thrust washers in the planetary gear set. When rebuilding, inspect the 2095209019 DIFFERENTIAL and 0631329086 SPRING PIN for wear, as they share the same load path.
