46554947 Doosan Drive Coupling Bushing

The 46554947 Doosan drive coupling bushing is \ inch factory OEM service part for the drive coupling system on Bobcat portable air compressors. Mounted between the coupling hub and the shaft, the bushing locks the hub in position and keeps the coupling running true, so the engine delivers torque to the airend without slip or runout. When the bushing wears, the first signs are vibration at the coupling housing, hammering under load changes, and accelerated wear on the flexible element.

Fitting a factory OEM bushing during coupling service restores the drive to its original alignment and gives the new element a sound mounting surface. Pair the 46554947 with the correct coupling element and fastener hardware so the machine goes back together in one service window.
