CHAPTER V
TORQUE CHART
BRAKE GROUP MOUNTING BOLT-NUT
Tighten the brake group mounting bolts to the torque values listed from the nut side. Since some of the mounting holes in the
steering knuckles are of conical design, the knuckle bolts must utilize conical mounting nuts to coincide with the mounting holes in
the knuckle. These conical nuts have a smooth cone surface and the torque values are considerably higher than the torque values for
regular nuts or prevailing type lock nuts.
