ZF 0730.063.141 RING | OEM Genuine Part

Overview

The ZF 0730.063.141 RING is a precision-engineered OEM genuine component designed to maintain critical sealing integrity within heavy-duty ZF construction machinery transmissions. This ring functions as a static or dynamic sealing element, preventing fluid bypass between rotating and stationary assemblies inside the gearbox. The SKU 0730.063.141 is specifically manufactured to OEM tolerances, ensuring a tight fit that sustains hydraulic pressure and lubrication flow. Positioned within the clutch drum or planetary gear set, this ring directly influences shift quality and torque delivery in demanding off-highway applications.

Symptoms of Failure

• Hydraulic pressure loss during gear engagement – A worn 0730.063.141 ring allows internal leakage, causing delayed or soft shifts in ZF transmissions.
• External oil seepage near the housing joint – When the ring degrades, transmission fluid may escape around the 4143101009: HOUSING or 4143301025: HOUSING, leaving visible drips on the casing.
• Erratic clutch engagement under load – A compromised ring disrupts the sealing circuit, leading to clutch chatter or momentary slipping when operating heavy machinery.
• Contaminated transmission fluid – Worn ring material can shed debris into the oil circuit, accelerating wear on adjacent components like the 0634313603: O-RING and 4475280018: SCREW PLUG.

Technical Specifications

Compatibility

This OEM genuine ring is engineered for ZF heavy-duty powershift transmissions commonly used in construction machinery. Based on its dimensional profile and sealing application, the 0730.063.141 is compatible with the following ZF transmission models: WG180, WG200, WG210, and WG250. It also fits select variants of the 4WG200 and 5WG200 series. Always verify the part number against your transmission’s parts manual before installation.
