ZF 0730.110.003 WASHER | OEM Genuine Part

Overview

The ZF 0730.110.003 WASHER is a precision-engineered OEM genuine shim component designed to maintain critical axial clearances within ZF heavy-duty transmission assemblies. This hardened steel washer sits between the differential housing and the taper roller bearing race, ensuring proper preload and alignment of the gear train. The SKU 0730.110.003 is frequently replaced during differential rebuilds to restore factory tolerances and prevent premature bearing wear. When installed alongside a 5838109012: DIFFERENTIAL, this washer ensures the ring gear maintains correct mesh depth with the pinion.

Symptoms of Failure

• Transmission whining noise during acceleration: A worn 0730.110.003 washer allows excessive axial play in the differential, causing the 0750117075: TAPER ROLLER BEARING to lose preload, resulting in a high-pitched whine under load.
• Oil seepage from the differential housing flange: As the washer compresses or fractures, the differential housing shifts, breaking the sealant bead and causing slow oil leaks around the housing mating surface.
• Intermittent gear slipping in lower ranges: Loss of washer thickness reduces clamping force on the 2093209023: DIFFERENTIAL assembly, leading to momentary torque loss during gear engagement.
• Vibration in the driveline at highway speeds: A collapsed washer allows the 5838300626: DIFFERENTIAL HOUSING to oscillate, transmitting vibration through the axle shafts.

Frequently Asked Questions

Q: Can I reuse the 0730.110.003 washer during a differential rebuild?
A: No. ZF specifies that this washer must be replaced with every differential service because it compresses plastically during initial torqueing. Reusing it will result in incorrect bearing preload and rapid failure of the 0750117075: TAPER ROLLER BEARING.

Q: How do I measure if the 0730.110.003 is worn?
A: Use a micrometer to measure thickness at three points around the circumference. If any reading is below 2.45 mm or varies by more than 0.05 mm, replace it immediately. A worn washer will cause the 5838300626: DIFFERENTIAL HOUSING to shift under load.

Q: Does this washer fit ZF WG180 and WG200 transmissions?
A: Yes, the 0730.110.003 is a standard shim in both WG180 and WG200 series. However, always cross-reference your transmission’s parts manual because some early WG200 units used a 2.30 mm washer.
