Starter Ring Gear Replacement
This manual explains the replacement procedure for the starter
ring gear on a motorcycle dynamometer.
Removing the Old Ring Gear
Step 1
If your dyno is equipped with a brake, it will be necessary to remove
it before proceeding. If your dyno is not equipped with a brake,
please proceed to step 2.
Remove the caliper assembly by removing the (4) 3/8 bolts that hold
it to the frame.
You will also need to remove the brake line from the caliper.
You may now remove the rotor from the dyno shaft. Remove the
bolts from the taper lock on the inner portion of the rotor. Use
those bolts to extract the taper lock by threading them into the offset
holes in the taper lock. The taper lock may need to pried out, but it
should be free at this point. Remove the rotor and set it aside.
