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. See CLUTCH PACKS  under OVERHAUL.
