Overview
The ZF 0730.062.680 BUSH is a precision-engineered wear component designed for the internal oil gallery and shaft support systems within the WG180 and WG200 series transmissions. This genuine OEM part acts as a critical bearing surface, reducing friction between rotating shafts and the stationary housing. The SKU 0730.062.680 is manufactured to exact ZF tolerances to ensure proper oil flow and alignment. When installed alongside the TRANSMISSION HOUSING, this bushing maintains the structural integrity of the gear train under high torque loads.
Symptoms of Failure
- Low oil pressure warning lights: A worn 0730.062.680 bushing allows pressurized oil to bypass the intended circuit, causing a drop in system pressure.
- Whining or grinding noise from the transmission bell housing: Excessive radial play from a degraded bushing creates metal-on-metal contact during gear engagement.
- Delayed engagement when shifting from Neutral to Drive: Oil starvation caused by a leaking bushing prevents the clutch packs from filling quickly.
- Visible metallic debris in the transmission fluid pan: Flaking bronze or steel particles from the bushing surface indicate imminent failure.

Compatibility
This bushing is a direct fit for the ZF WG180 and WG200 series transmissions. It is specifically used in the output shaft support area and the reverse clutch drum assembly. The part also applies to certain variants of the WG210 series where the same bushing bore geometry is employed. Always verify the part number 0730.062.680 against your transmission’s serial plate before installation. For complete assembly, this bushing works in conjunction with the OUTPUT FLANGE and the DISCONNECTION unit to ensure proper torque transfer.
