ABSTRACT:
A power takeoff assembly, a drive assembly, a saw and a kit for a saw include a drive plate and drive shaft, for example for mounting to a fly wheel, and a bell housing for mounting to an engine block and for supporting a sheave. The sheave rotates on bearings supported by a housing tube on the bell housing, and a coupler couples the drive shaft, which extends into the tube, to the sheave. Side loading and cyclical loading on the drive shaft are reduced, dimensions of the saw can be reduced and operation of the saw can be more reliable.
