ABSTRACT:
A drum pedal assembly has a shaft, a bushing and a balancer. The shaft has a first end. The bushing is mounted securely around the first end and has two ends and a through hole. The through hole of the bushing is defined axially through the bushing and is mounted around the first end. The balancer is mounted securely around the bushing and has an outer surface, a shaft hole, a threaded hole and a bolt. The shaft hole is defined axially through the balancer and is mounted around the bushing. The threaded hole is mounted radially in the outer surface of the balancer and communicates with the shaft hole. The bolt is mounted in the threaded hole and presses against the shaft. When the bushing is worn, only the worn bushing has to be replaced.
