ZF 0730.110.738 WASHER | OEM Genuine Part

Overview

The ZF 0730.110.738 WASHER is a precision-engineered OEM genuine component designed to maintain critical axial clearances within the differential and final drive assemblies of heavy-duty construction machinery transmissions. This hardened steel washer acts as a load-bearing shim between rotating and stationary components, ensuring proper gear mesh and preventing metal-on-metal contact. The SKU 0730.110.738 is specifically calibrated to withstand high torque loads and thermal expansion cycles found in ZF powershift transmissions. When installed alongside the 5838109012: DIFFERENTIAL, it provides the necessary end-play control for optimal power transfer in demanding off-road applications.

Symptoms of Failure

• Transmission oil leaks from axle housing seals: A worn 0730.110.738 washer allows excessive axial movement, distorting seal surfaces and causing fluid seepage around the differential carrier.
• Gear slipping under load during excavation: When the washer thickness degrades, gear engagement depth decreases, leading to intermittent power loss when the machine is under heavy strain.
• Metallic grinding noise during turns: Insufficient washer support causes the 0750117075: TAPER ROLLER BEARING to misalign, producing a distinct grinding sound from the final drive area.
• Vibration in the driveline at low speeds: A collapsed washer creates uneven preload on the 2093209023: DIFFERENTIAL, causing harmonic vibrations that worsen as the machine accelerates.

Technical Specifications

Compatibility

This washer is a critical component in ZF WG180, WG200, and WG310 series powershift transmissions commonly used in wheel loaders, graders, and telehandlers. It fits specifically within the differential carrier assembly where it interfaces with the 5838300626: DIFFERENTIAL HOUSING. The 0730.110.738 is also compatible with ZF 4WG-200 and 6WG-200 models produced after 2005. Always verify the washer thickness against your transmission’s service manual, as multiple shim sizes are used to achieve precise preload settings.

Frequently Asked Questions

Q: How do I know if the 0730.110.738 washer needs replacement?
A: Measure the washer thickness with a micrometer. If it has worn below 2.3 mm (original 2.5 mm), or if you observe any of the failure symptoms listed above, replacement is necessary to prevent damage to the 0750117075: TAPER ROLLER BEARING.

Q: Can I reuse this washer if it looks clean?
A: No. ZF OEM washers are single-use components. Even slight wear alters the preload on the differential assembly, leading to premature failure of the 5838109012: DIFFERENTIAL.

Q: Does this washer fit ZF 4WG-200 transmissions?
A: Yes, the 0730.110.738 is compatible with ZF 4WG-200 and 6WG-200 models, provided it is used in conjunction with the correct 5838300626: DIFFERENTIAL HOUSING and shim stack.
