On-Vehicle Testing

NOTE: Torque required to rotate wheel may decrease when wheel is turning.
  1. Raise one wheel off ground, leaving opposite wheel firmly on ground. Install Traction-Lok Torque Adapter (T59L-4204-A) on mounting studs of raised wheel. Shift transmission into Neutral. Attach traction-lok torque adapter to torque wrench.
  2. Using torque wrench to rotate wheel, note torque required to keep wheel rotating through several revolutions. If break-away torque (torque required to start wheel rotating) is not at least 20 ft. lbs. (27 N.m), and wheel does not turn smoothly without slipping, adjust clutch pack preload.
