Countershaft Kit for 9″ Absorbers ease fabrication of custom engine-dynamometer stands for many small-engine test applications. Package includes heat-treated and machined stainless-steel shaft with an end taper that directly accepts our popular 9″ size “snowmobile” DYNOmite absorber. Carbon-fiber reinforced 14mm synchronous drive belt, pulleys, and machinable Taper-Loc hub insert are designed to couple the engine’s output shaft to this countershaft. A pair of low-friction ball bearings (in self-aligning spherical-bearing blocks with locking collars) is supplied for easy shaft mounting and initial belt-tension adjustment – on your own floor- or bench-mounted engine-testing frame.
