Step 3
Align the retarder with the dyno.
- Remove the top bolt of the torque arm so that
the middle of the retarder can swivel.
- Place a straight edge across the apex of the drum
and across the retarder. (Swivel the middle of
the retarder as necessary for clearance.)
- Measure down to the collars on the axle shaft of
the retarder (not the black bearing locking
collars!). Shim the retarder or the dyno until the
collars are 7 19/32" (19.288 cm) down from the
top of the drum on the dyno +/- 1/16" (1.58 mm).
