Overview
The ZF 0730.111.764 WASHER is an OEM genuine shim component engineered specifically for the WG 200 series powershift transmissions. This precision-ground washer functions as a critical axial spacer within the planetary gearset assembly, ensuring correct preload and alignment between rotating elements. Installed between the sun gear and the 4460115043 HOUSING, it maintains exact end-play tolerances that prevent gear clash and bearing overload. The SKU 0730.111.764 identifies this as a factory-original ZF part, manufactured to the same metallurgical and dimensional standards as the unit’s original build specification.
Symptoms of Failure
When the 0730.111.764 washer wears beyond service limits, operators typically encounter these specific failure modes:
- Transmission oil leaks at the axle drive housing interface – A worn washer reduces clamping force on the 4469315012 AXLE DRIVE HOUSING, allowing ATF to seep past the seal.
- Gear slipping under load in forward ranges – Incorrect axial clearance causes the clutch packs to lose full engagement, resulting in momentary power loss during acceleration.
- Abnormal whining noise from the planetary section – Excessive end-play forces the 0750117406 TAPER ROLLER BEARING to operate outside its designed contact pattern, generating high-frequency vibration.
- Hard shifting between 2nd and 3rd gear – The worn shim alters the stack height, which delays hydraulic timing and produces harsh engagement.

Compatibility
This washer is a direct-fit component for the ZF WG 200 series transmission family. It is also compatible with the WG 180, WG 210, and WG 220 models that share the same planetary carrier architecture. The 0730.111.764 is frequently replaced in conjunction with the 0750117802 TAPERED ROLLER BEARING during a full gearset rebuild. Always verify the stack height using a dial indicator; if the measured end-play exceeds 0.15 mm, this washer must be swapped to prevent damage to the adjacent housing and bearing races.
