Wheel Bolt Tightening Sequence

IMPORTANT: Wheel bolts must be clean and oil-free when torquing. Torque values specified in the following steps are for clean, dry wheel bolts. Lubricating oil reduces friction and thread bit to overload bolts.

• Initial Wheel Bolt Torque:

1. Using tightening sequence shown, tighten wheel bolts to specification. Use criss-cross pattern to pull wheel tight evenly against hub.

   Item	Measurement	Specification
   Wheel Bolts	Initial Torque	200 N·m (150 lb.-ft.)

   A - Socket, 30 mm (3/4 In. Drive)

   B - Extension, 3/4 x 10 In.

   C - 4 to 1 Torque Multiplier

   D - Extension, 1/2 x 10 In.

   E - Wrench, Torque or Ratchet

   F - Bolt Heads

   • Final Wheel Bolt Torque:

   IMPORTANT: Final wheel bolt torque is very high and cannot be reached using common hand tools and torque wrench. A Four-To-One Torque Multiplier is required to reach final wheel bolt torque. To achieve high torque results, final torque must be done with tire on the ground and multiplier handle against inside of rim.

2. Position tools (A—E) as shown, with Torque Multiplier handle against inside of rim.

3. Turn all bolt heads (F) an additional 1/4 turn, past initial torque value. When using a 4 to 1 torque multiplier, the torque wrench makes one full turn while bolt head makes 1/4 a turn.
