MAINTENANCE
3. Snug up flange nuts alternately in the sequence shown. Rotate wheel assembly one-half turn to allow the wheel
to seat. DO NOT tighten them fully until all have been seated. This procedure will permit the uniform seating of
nuts and ensure the even, face-to-face contact of wheels and hub.

4. Tighten flange nuts fully, using the same alternating sequence. In each case, be sure to tighten wheel nuts only
to the torque level recommended in the table and to maintain them at that level through planned, periodic
checks.
5. Check torque on wheel nuts after the first 50 to 100 miles of service.

1. Mount wheel or inner dual wheel over studs, being careful not to damage stud threads.
2. Spin on the outer cap nuts on the front wheel, or inner cap nut on the rear wheel.
