ZF 0630.513.158 SNAP RING | OEM Genuine Part

Overview

The ZF 0630.513.158 SNAP RING is an OEM genuine retaining component engineered for precise axial positioning within heavy-duty construction machinery transmissions. This snap ring secures internal assemblies, such as gear clusters and bearing packs, against axial displacement during high-torque operation. It sits in a machined groove on shafts or inside housings, ensuring that rotating elements remain locked in their designated positions. The part number 0630.513.158 is a critical identifier for maintaining factory-specified clearances in ZF drivetrains. When paired with a 4143101022 HOUSING or a 4143301044 HOUSING, this snap ring prevents costly internal contact between moving parts.

Symptoms of Failure

• Transmission gear slippage under load: A worn or broken snap ring allows shafts to shift axially, causing gears to lose proper mesh engagement during operation.
• Abnormal metallic rattling or grinding noises: When the snap ring fails, internal components drift out of position, creating intermittent contact with adjacent parts like the 0631329135 SPRING PIN.
• Oil leaks from housing joints: Axial movement of the shaft can distort seal surfaces, leading to fluid seepage around the 0636302014 SCREW PLUG and gasket interfaces.
• Vibration during gear changes: Loss of retaining force causes the shaft to oscillate, transmitting harsh vibrations through the driveline during shifts.

Technical Specifications

Compatibility

This snap ring is designed for ZF powershift transmissions commonly found in construction machinery. It is compatible with the WG180, WG200, and WG210 series, where it retains planetary gear sets and output shafts. The part also fits select models in the Ergopower and Ecolite families. For proper installation, verify groove dimensions against the 4143301053 CONNECTING PART and the 0634801057 SEALING RING to ensure concentric alignment.
