ZF 0730.110.014 WASHER | OEM Genuine Part

Overview

The ZF 0730.110.014 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 taper roller bearing assembly, maintaining critical end-play tolerances that prevent gear train misalignment. As a factory-specification part, the SKU 0730.110.014 ensures that the differential and axle components operate within their designed load distribution parameters. When installed alongside the 5838109012: DIFFERENTIAL and the 0750117075: TAPER ROLLER BEARING, this washer forms the foundational spacing layer that absorbs axial thrust forces during high-torque operations.

Symptoms of Failure

• Transmission oil seepage at axle housing seals – A worn 0730.110.014 washer allows excessive bearing play, which distorts seal alignment and causes hydraulic fluid to weep from the differential housing interface.
• Intermittent gear slipping under load – When the washer thickness degrades, the 2093209023: DIFFERENTIAL assembly loses preload, resulting in momentary power loss during excavation or grading operations.
• Metallic grinding noise from transmission center section – Insufficient washer thickness permits metal-on-metal contact between the bevel gear and housing, producing a distinct high-pitched whine during deceleration.
• Vibration through driveline at steady speeds – Uneven washer wear creates axial runout that transmits harmonic vibrations through the 5838300626: DIFFERENTIAL HOUSING, often misdiagnosed as a bearing failure.

Technical Specifications

Compatibility

This OEM washer is dimensionally validated for ZF WG180, WG200, and WG250 series powershift transmissions commonly deployed in wheel loaders, excavators, and telehandlers. It also fits select ZF 4WG-200 and 6WG-250 models where the differential preload specification requires a 2.50 mm shim. Always verify axial clearance after installation using a dial indicator; the 0730.110.014 is designed to work in conjunction with the 5838300811: THRUST WASHER and 5838300721: AXLE BEVEL GEAR to maintain factory tolerances.

Frequently Asked Questions

Q: Can I reuse the 0730.110.014 washer during a transmission rebuild?
A: No. This is a single-use selective shim. Reusing it risks incorrect preload, leading to premature bearing failure. Always install a new OEM washer and measure axial clearance.

Q: How do I know if the 0730.110.014 is the correct thickness for my ZF transmission?
A: The thickness is determined by measuring the gap between the differential housing and bearing race using a feeler gauge. If the gap exceeds 2.50 mm, a thicker shim from the ZF selective range is required.

Q: Does this washer fit ZF 4WG-200 transmissions with serial numbers after 2015?
A: Yes, the 0730.110.014 is backward-compatible with all ZF WG-series transmissions that use a 68 mm outer diameter shim pocket. Verify housing casting marks for confirmation.
