ZF 0730.110.397 WASHER | OEM Genuine Part

Overview

The ZF 0730.110.397 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 planetary gear sets and bearing races, maintaining critical end-play tolerances that prevent gear clash and bearing preload loss. As a factory-specification part, the SKU 0730.110.397 ensures exact dimensional consistency for ZF power shift transmissions operating under extreme torque loads. When installed alongside the 5838109012: DIFFERENTIAL, this washer stabilizes the differential carrier assembly, reducing vibration transfer to adjacent components.

Symptoms of Failure

• Transmission oil leaks at axle housing seals: A worn 0730.110.397 washer allows excessive axial play, distorting the 5838300626: DIFFERENTIAL HOUSING seal surface and causing fluid seepage.
• Gear slipping under load during excavation: Thinning of this washer reduces clamping force on the 0750117075: TAPER ROLLER BEARING, allowing the bearing cone to shift and interrupt power flow.
• Metallic grinding noise from transmission sump: When the washer fractures, debris contaminates the 2093209023: DIFFERENTIAL gear mesh, producing audible chatter during deceleration.
• Intermittent drive engagement in reverse gear: Worn clearance from a collapsed washer causes the output shaft to float, delaying clutch pack engagement.

Technical Specifications

Compatibility

This washer is dimensionally validated for ZF WG180, WG200, and WG211 power shift transmissions commonly used in wheel loaders, dozers, and excavators. It also fits select ZF 4WG-310 and 6WG-260 models where the differential housing uses a 42mm pilot bore. Always verify stack height against the 5838300811: THRUST WASHER and 5838300721: AXLE BEVEL GEAR during rebuilds.

Frequently Asked Questions

Q: Can the 0730.110.397 washer be reused during a transmission rebuild?
A: No. This OEM shim is a single-use component because its case-hardened surface deforms plastically during initial torque application. Reusing it will result in incorrect bearing preload and premature failure of the 0750117075: TAPER ROLLER BEARING.

Q: How do I measure the correct thickness for replacement?
A: Use a micrometer to measure the stack height between the differential housing bore and the bearing outer race. Subtract the measured gap from the factory specification (typically 0.05-0.15mm preload) to select the appropriate washer thickness.

Q: Does this part fit ZF 6WG-200 transmissions?
A: Yes, but only in models produced after 2012 that use the updated differential housing (part 5838300626). Earlier units require a 3.0mm thick washer.
