Overview
The ZF 0730.108.133 THRUST WASHER is a precision-engineered component designed specifically for the WG 200 series transmission. This OEM genuine part acts as a critical axial bearing surface, positioned between rotating shafts and stationary housings within the planetary gear set. It absorbs and distributes thrust loads generated during gear shifts and torque conversion, preventing metal-to-metal contact. The SKU 0730.108.133 is manufactured to exact ZF tolerances, ensuring minimal axial play and consistent oil film retention. When installed alongside a 4460165051: CONSOLE or a 4460368311: CONSOLE, this washer maintains proper gear alignment and prevents premature wear on adjacent components.
Symptoms of Failure
- Erratic gear engagement and slipping: A worn 0730.108.133 thrust washer reduces axial clearance, causing delayed or harsh shifts in WG200 transmissions during load changes.
- Low oil pressure warnings: Excessive wear on this washer allows axial movement that disrupts oil flow channels, triggering pressure drops and potential overheating.
- Metallic debris in transmission fluid: As the thrust washer degrades, bronze or steel particles contaminate the oil, often visible during routine drain intervals.
- Vibration during acceleration: A failing washer creates uneven load distribution, leading to noticeable driveline shudder when climbing grades or towing.

Compatibility
This thrust washer is primarily engineered for the ZF WG200 series transmissions, including models WG200, WG180, and WG150. It fits both standard and heavy-duty variants used in construction, agricultural, and material handling equipment. The 0730.108.133 also cross-references with certain WG120 and WG160 applications where axial thrust loads are similar. Always verify clearance when pairing with a 0636011429: HEXAGON SCREW or a 0730100365: WASHER to ensure proper stack height.
