ZF 0730.110.083 WASHER | OEM Genuine Part

Overview

The ZF 0730.110.083 WASHER is a precision-engineered OEM genuine component designed to maintain critical axial clearances within heavy-duty construction machinery transmissions. This hardened steel washer sits between planetary gear sets and the differential housing, ensuring proper load distribution and preventing metal-on-metal contact during high-torque operations. As an original ZF part, the SKU 0730.110.083 guarantees exact dimensional tolerances required for long service life in demanding environments. When installed alongside the 5838109009: DIFFERENTIAL, it forms a critical wear surface that protects both the axle bevel gear and the housing from premature failure.

Symptoms of Failure

• Transmission oil leaks near the differential housing: A worn 0730.110.083 washer allows axial play, breaking the seal between the 5838300626: DIFFERENTIAL HOUSING and the output shaft, leading to visible fluid seepage.
• Gear slipping under load in construction machinery: When this thrust washer loses its surface hardness, the 0750117075: TAPER ROLLER BEARING loses preload, causing intermittent power loss during excavation or grading.
• Metallic grinding noise from the transmission sump: Excessive clearance from a collapsed washer allows the 2093209023: DIFFERENTIAL gears to contact the housing, producing a distinct grinding sound at low RPM.
• Increased backlash in the driveline: A degraded washer permits lateral movement of the differential assembly, causing a clunking sensation when shifting between forward and reverse.

Technical Specifications

Compatibility

This washer is primarily used in ZF WG180, WG200, and WG210 series powershift transmissions found in wheel loaders, graders, and dump trucks. It also fits select ZF 4WG-200 and 6WG-200 models from 1998-2015. Always verify by cross-referencing your transmission serial number with the SKU 0730.110.083.

Frequently Asked Questions

Q: Can I reuse the ZF 0730.110.083 washer during a transmission rebuild?
A: No. This is a single-use crush washer that deforms during initial torque application. Always replace with a new OEM genuine part to maintain proper preload on the taper roller bearing assembly.

Q: How do I know if the 0730.110.083 washer is compatible with my ZF WG200 transmission?
A: Check the transmission model plate located on the bell housing. The WG200 series uses this washer in the differential output section. If your serial number includes “0730” in the parts list, it is compatible.

Q: What torque specification should I use when installing this washer?
A: Refer to the ZF service manual for your specific transmission model. Typical torque for the retaining nut over this washer is 250-300 Nm, but always verify with the OEM documentation to avoid over-compression.
