Overview
The ZF 0659.055.110 PLUG-IN BUSH is a precision-engineered component designed for the WG180 and WG200 transmission series. This OEM genuine part serves as a critical interface within the planetary gearset assembly, ensuring accurate alignment and load distribution between rotating shafts and stationary housings. The SKU 0659.055.110 is specifically manufactured to ZF’s exacting tolerances, providing a press-fit solution that minimizes vibration and wear in high-torque applications. When installed alongside the 4644105413: DISCONNECTION mechanism, this bushing maintains proper gear mesh geometry under heavy load conditions.
Symptoms of Failure
- Oil seepage at the transmission housing interface — A worn 0659.055.110 bushing often causes hydraulic fluid to bypass the seal, leading to visible drips near the output flange area. This is a common “ZF transmission oil leak” search query.
- Abnormal gear whine or grinding noise — As the bushing wears, radial play increases, causing gear teeth to misalign. Operators frequently report “WG200 transmission whining noise” during acceleration.
- Delayed engagement or gear slipping — Excessive bushing clearance allows the shaft to shift axially, resulting in “ZF WG180 slipping gears” symptoms, particularly in reverse or low-range operation.
- Vibration through the driveline — A degraded plug-in bushing can induce harmonic vibrations, often described as “transmission shudder at highway speeds” in diagnostic forums.

Compatibility
This plug-in bushing is engineered for the ZF WG180 and WG200 series transmissions, commonly found in medium-duty trucks, buses, and off-highway equipment. It is a direct replacement for the original bushing installed in the transmission housing bore. When replacing this part, technicians should also inspect the 4642303093: OUTPUT FLANGE for scoring, and verify that the 0636021010: HEXAGON SCREW securing the assembly meets torque specifications. The bushing seats directly against the 4644101222: TRANSMISSION HOUSING, making housing bore condition critical for proper fitment.
