ZF 0730.110.084 WASHER | OEM Genuine Part

Overview

The ZF 0730.110.084 WASHER is a precision-engineered OEM genuine component designed to maintain critical axial clearances within heavy-duty ZF transmissions. This hardened steel washer sits between rotating gear assemblies and housing surfaces, acting as a load-bearing interface that prevents metal-on-metal contact. As part of the differential and final drive assembly, the SKU 0730.110.084 ensures consistent preload on adjacent bearings and gears, directly influencing torque distribution and drivetrain longevity. When installed alongside a 5838109009: DIFFERENTIAL, this washer stabilizes the entire gear stack under high-load conditions.

Symptoms of Failure

• Transmission oil leaks around the differential housing: A worn 0730.110.084 washer allows excessive axial movement, compromising the seal between the 5838300626: DIFFERENTIAL HOUSING and the output shaft, leading to visible fluid seepage.
• Gear slipping under load during excavation: Reduced washer thickness alters the preload on the 0750117075: TAPER ROLLER BEARING, causing intermittent torque loss in the final drive.
• Abnormal whining or grinding from the axle area: A collapsed washer creates uneven contact patterns between the 2093209023: DIFFERENTIAL gears, generating metallic noise during turns.
• Premature bearing failure in the differential carrier: Insufficient washer height leads to bearing race fretting, detectable as vibration through the chassis at operating temperature.

Technical Specifications

Compatibility

This washer is engineered for ZF WG-series transmissions commonly used in construction machinery. It is a direct fit for the following models: WG180, WG200, WG210, WG240, WG250. The 0730.110.084 is also found in select ZF ERGOPOWER and ECOMID drivelines where the differential assembly uses a 62.5 mm shaft journal. Always verify clearance against the 5838300811: THRUST WASHER stack height when rebuilding the carrier.

Frequently Asked Questions

Q: Can I reuse the ZF 0730.110.084 washer during a rebuild?
A: No. This is a single-use crush washer that deforms during installation to set bearing preload. Reusing it will result in incorrect clearance and rapid wear of the 0750117075: TAPER ROLLER BEARING.

Q: How do I identify if my WG200 transmission needs this specific washer?
A: Measure the existing washer thickness. If it measures below 2.45 mm at any point, or if you observe scoring on the differential housing face, replace it immediately with the 0730.110.084.

Q: Does this washer work with aftermarket differentials?
A: It is designed for OEM ZF differentials. When using a 5838109009: DIFFERENTIAL, always pair it with the genuine washer to maintain factory tolerances.
