Overview
The ZF 0730.007.629 SHIM is a precision-engineered adjustment component specifically designed for the WG 65 series of heavy-duty transmissions. This OEM genuine part functions as a critical spacer within the planetary gearset assembly, controlling axial clearances and ensuring correct preload between rotating and stationary elements. By maintaining precise tolerances, the 0730.007.629 shim prevents gear train misalignment and reduces internal stress on adjacent components. It is commonly installed during rebuilds or upgrades alongside the 4616101066: TRANSMISSION HOUSING and the 0636011118: HEXAGON SCREW to secure the assembly. The SKU 0730.007.629 is manufactured to ZF’s original specifications, guaranteeing a direct fit without modification.
Symptoms of Failure
When the ZF 0730.007.629 shim wears or becomes damaged, several distinct operational issues emerge. Excessive axial play in the output shaft is a primary indicator, often detected during routine maintenance checks. Intermittent gear slipping under load occurs as clearance tolerances widen, reducing clutch pack engagement pressure. Low-frequency vibration during torque converter lockup signals uneven load distribution across the planetary set. Metallic debris in transmission fluid may appear as the shim surface degrades, contaminating the hydraulic circuit. These symptoms frequently require replacement of the shim along with inspection of the 4616301307: HOUSING and 4616301309: HOUSING for wear patterns.

Compatibility
This shim is engineered for the ZF WG 65 series transmission family, which includes the WG65, WG80, WG120, WG150, WG180, and WG200 models. It is specifically used in the planetary carrier-to-sun gear interface. The 0730.007.629 also fits select ZF Ecomat 4HP and 5HP variants that share the WG65 planetary architecture. Always verify clearance requirements using a feeler gauge before final assembly. For complete rebuilds, pair this shim with the 0636011038: HEXAGON SCREW and 0636016015: HEXAGON SCREW for torque-critical fastening.
