Apply Tooling (E) or a light coat of oil onto the wheel studs after the wheel has been fully seated to avoid contamination of the mating surfaces. Anti-seize may be preferred in corrosive environments to make nut removal easier when removing rims. No other anti-seize compound is to be used.
Apply Tooling (E) or a light coat of oil onto four of the wheel studs that are equally spaced and approximately 90 degrees apart. Install four nuts (6) and four washers (5) to secure tire and rim (4) onto the wheel.
Apply Tooling (E) or a light coat of oil onto the remaining wheel studs.
Install the remaining nuts (6) and washers (5). Use Tooling (C) to tighten nuts (6) to a torque of 3100 350 N m (2286 258 lb ft).Note: Apply a light coat of oil to the faces of the washers.
