Overview
The ZF 2095.346.111 THRUST WASHER is a precision-engineered OEM genuine component designed to manage axial loads and maintain critical clearances within ZF heavy-duty transmissions. Positioned between rotating gear sets and stationary housings, this thrust washer prevents metal-to-metal contact, reducing friction and heat buildup in the differential assembly. The SKU 2095.346.111 is specifically calibrated for use in construction machinery transmissions, where it supports the 2095109016: DIFFERENTIAL and 2095209037: DIFFERENTIAL units. Its hardened surface ensures consistent oil film retention, directly contributing to the longevity of surrounding components like the 0750117075: TAPER ROLLER BEARING and the 2095309059: DIFF.HOUSING.
Symptoms of Failure
- Transmission whining or grinding noise during turns: A worn 2095.346.111 thrust washer allows excessive axial play, causing gear teeth to clash under load. This is often misdiagnosed as a failing bearing.
- Metallic debris in transmission oil: As the washer surface erodes, fine steel particles contaminate the lubricant, accelerating wear on the 2095309081: DIFFERENTIAL AXLE and other planetary gears.
- Intermittent gear slippage under heavy load: Loss of thrust clearance reduces clamping force on clutch packs, leading to momentary power loss when excavating or lifting.
- Elevated operating temperatures near the differential housing: Increased friction from a collapsed washer generates localized heat, potentially warping the 2095309059: DIFF.HOUSING over time.

Compatibility
This thrust washer is engineered for ZF WG-series transmissions commonly used in wheel loaders, telehandlers, and graders. It is a direct fit for the following models:
- ZF WG180 (all variants)
- ZF WG200 (series 2 and 3)
- ZF WG210 (early production runs)
- ZF 4WG-200 (with differential lock option)
Always verify your transmission serial number before installation. The 2095.346.111 interfaces directly with the 4482360002: AXLE BEVEL GEAR and the 4482360001: DIFFERENTIAL BEVEL GEAR to maintain proper gear mesh depth.
