The following instructions are for both the model 200i/250i above ground and
200iP/250iP pit motorcycle dynamometers. If you are not installing the air brake skip

Turn off the dyno and disconnect the AC power cord from its power source.
2 Insert the woodruff key into the dyno shaft.
3 Slide the brake rotor with taper lock onto the shaft and align it, so that the taper
lock touches the bearing lock collar on the dyno shaft.
4 Set up a dial indicator on the disc braking surface to measure the run-out. The
maximum allowable run-out is +/- 0.005 inches.
5 Tighten the three bolts in a clockwise rotation to help minimize the run out,
torquing to 15 foot-pounds.
Note: If necessary, readjust the taper lock and brake rotor to ensure the run-out is
less than +/- 0.005 inches.
Note: For clarity, only the drum module is shown.
