ZF 0730.063.024 RING | OEM Genuine Part

Overview

The ZF 0730.063.024 RING (SKU: 0730.063.024) is an OEM genuine internal retaining component engineered for precision fit within ZF powershift transmissions. This ring functions as a critical axial stop, securing planetary gear sets and clutch packs against the housing bore to prevent unwanted movement under high torque loads. Positioned directly inside the transmission drum assembly, the 0730.063.024 ring interfaces with the 4143101009: HOUSING and the 4143301025: HOUSING to maintain proper gear alignment. Without this ring, the entire rotating assembly can shift axially, leading to catastrophic internal contact.

Symptoms of Failure

When the ZF 0730.063.024 ring fatigues or cracks, operators typically notice these specific failure modes:

• Intermittent gear slipping under load – The ring no longer holds the clutch pack in place, causing momentary loss of drive torque.
• Metallic rattling from the transmission housing – A loose ring allows planetary gears to chatter against the 4143101009: HOUSING.
• Contaminated transmission fluid with metallic debris – Worn ring fragments circulate through the system, often lodging in the 0634313603: O-RING sealing surfaces.
• Hard shifting or delayed engagement – Axial play from a broken ring prevents proper hydraulic pressure buildup against the 4475280018: SCREW PLUG passages.

Technical Specifications

Compatibility

This genuine ZF ring is designed for the following transmission model families where it secures the sun gear or clutch drum:

• ZF WG180 – All series (WG180, WG180C, WG180E)
• ZF WG200 – WG200, WG200C, WG200E variants
• ZF WG120 – Select configurations with 63mm bore drums
• ZF 4WG-200 – Powershift models used in construction loaders

Always verify the ring groove diameter in your specific 4143101009: HOUSING before installation. The ring must seat fully without gaps.
