ZF 0730.110.013 WASHER | OEM Genuine Part

Overview

The ZF 0730.110.013 WASHER is an OEM genuine shim component engineered to maintain precise axial clearance within heavy-duty construction machinery transmissions. This precision-ground washer sits between planetary gear sets and bearing assemblies, ensuring correct load distribution and preventing metal-to-metal contact during high-torque operations. As a critical spacer in the differential housing stack-up, the SKU 0730.110.013 directly influences gear mesh alignment and overall drivetrain longevity. When paired with a 5838109012: DIFFERENTIAL, this washer stabilizes the rotating assembly under extreme axial loads common in excavators and wheel loaders.

Symptoms of Failure

• Transmission oil seepage around differential housing: A worn 0730.110.013 washer allows excessive end-play, compromising the seal between the 5838300626: DIFFERENTIAL HOUSING and output shaft, leading to visible fluid loss.
• Intermittent gear slipping under load: When this thrust washer loses its calibrated thickness, the 0750117075: TAPER ROLLER BEARING loses preload, causing momentary power loss during digging or grading operations.
• Metallic grinding noise from transmission sump: Insufficient washer height permits the 2093209023: DIFFERENTIAL gear teeth to contact the housing wall, producing a distinct scraping sound at low RPM.
• Vibration in drive axles during acceleration: Uneven washer wear creates axial runout, transferring cyclic vibrations through the driveline that worsen with load.

Technical Specifications

Compatibility

This genuine ZF washer is primarily specified for the WG180 and WG200 series powershift transmissions used in construction machinery. It also fits select WG211 and WG310 models where differential preload shimming is required. Always verify stack height against service manual specifications when replacing this component alongside a 5838300811: THRUST WASHER or 5838300721: AXLE BEVEL GEAR.

Frequently Asked Questions

Q: Can I reuse the 0730.110.013 washer during a transmission rebuild?
A: No. ZF specifies single-use only for this hardened washer. Reusing it risks incorrect preload and accelerated bearing wear, especially when installing a new 0750117075: TAPER ROLLER BEARING.

Q: How do I verify the correct thickness of this washer?
A: Measure the axial clearance between the differential housing and bearing race using a dial indicator. The service manual for WG180 transmissions specifies 0.05-0.15 mm end-play with the 0730.110.013 installed.

Q: Does this washer fit ZF 4WG-200 transmissions?
A: Yes, it is compatible with 4WG-200 models when used in the differential preload stack. Always cross-reference with the 5838300818: THRUST WASHER for proper shim selection.
