ZF 0730.063.293 RING | OEM Genuine Part

Overview

The ZF 0730.063.293 RING is an OEM genuine precision component engineered for the internal sealing architecture of heavy-duty ZF powershift transmissions. This ring sits within the clutch pack or hydraulic circuit assembly, functioning as a critical static seal to prevent cross-port leakage between high-pressure oil galleries. As an original ZF part, SKU 0730.063.293 ensures exact dimensional tolerances required for maintaining consistent clutch engagement pressure in construction machinery transmissions. When installed alongside a 4143101009 HOUSING or a 4143301025 HOUSING, this ring completes the sealing boundary that directs hydraulic flow to the correct clutch pack.

Symptoms of Failure

• Intermittent gear slipping under load: A worn 0730.063.293 ring allows pressurized oil to bypass the intended clutch circuit, causing torque loss during heavy digging or grading operations.
• Delayed engagement when shifting: Hydraulic pressure bleed past a degraded ring results in sluggish clutch fill times, particularly noticeable in cold-start conditions on wheel loaders.
• External oil seepage at housing joints: Failure of this ring can manifest as weeping oil around the transmission case split line, often misdiagnosed as a gasket issue.
• Erratic transmission temperature spikes: Internal leakage generates excessive heat from clutch slip, triggering thermal warnings on construction machinery dashboards.

Technical Specifications

Compatibility

This ring is designed for ZF WG series transmissions commonly found in construction machinery. Primary applications include the WG180 and WG200 models, as well as the WG120 and WG150 series used in telescopic handlers and compact loaders. It also appears in certain 4WG200 and 6WG200 variants where the ring functions within the clutch housing assembly. Always verify your transmission model code before ordering.
