ZF 0501.314.839 WASHER | OEM Genuine Part

Overview

The ZF 0501.314.839 WASHER is a precision-engineered OEM genuine component designed to maintain critical axial clearances within ZF heavy-duty transmission assemblies. This hardened steel washer functions as a load-spreading interface between rotating and stationary elements, preventing metal-on-metal contact that can lead to premature wear. Commonly found in construction machinery drivelines, the SKU 0501.314.839 sits adjacent to the 4108101140: HOUSING and the 0501211694: MOTOR assembly, where it absorbs thrust loads during gear shifts and torque conversion. Its precise thickness ensures proper preload on bearings and shafts, directly influencing transmission longevity.

Symptoms of Failure

• Transmission oil seepage near the housing joint – A worn 0501.314.839 washer can distort under load, creating gaps that allow hydraulic fluid to escape past the 0501314793: COVER seal.
• Intermittent gear slipping under heavy load – Deteriorated washer thickness reduces clutch pack clamping force, causing power loss during excavation or grading operations.
• Metallic grinding noise from the transmission sump – Flattened or cracked washers permit shaft end-play, leading to contact between the 0501314799: BUSH and adjacent gear faces.
• Erratic shift timing in automatic modes – Insufficient washer height alters hydraulic pressure modulation, delaying clutch engagement in ZF WG-series transmissions.

Technical Specifications

Compatibility

This washer is engineered for ZF WG-series powershift transmissions commonly deployed in wheel loaders, dozers, and telehandlers. It is a direct fit for WG180, WG200, and WG250 models, where it is installed between the sun gear shaft and the 4108101140: HOUSING. It also appears in certain 4WG-200 and 6WG-250 variants used in off-highway construction equipment. Always verify stack height using the original service manual before installation.
