PRO-TORQ SPINDLE NUT (Cont.)
NOTE
The Pro-Torq spindle nut is composed of two parts, the nut
and a steel spring keeper which is painted orange on the
side that must be facing out.
REMOVAL
1.
Use a small blade screwdriver to carefully pry each keeper arm from the undercut groove in
the nut and release the orange keeper from the nut. The arms are on opposite sides of the
open end of the keeper.
WARNING
A new orange keeper arm must be replaced if it is damaged when
removed or installed in the nut. It is recommended to replace the
keeper arm each time it is removed. The original nut may be reused,
the original keeper may be re -used if not damaged. Failure to heed
this WARNING may cause injury or death to personnel and damage
to the equipment due to wheel-end loss.
CAUTION
Failure to remove the orange keeper before removing the nut will
result in damaged threads to both the nut and the axle end spindle.
Over torque of the nut will result in stripped threads.
INSTALLATION
1.
Thread the nut, without keeper arm, onto the axle spindle threaded end, keeper side facing
out. Hand tighten nut against outer bearing.
2.
While slowly rotating the wheel/hub use a torque wrench and socket to torque the nut to 200
lb-ft (271 Nm). Wheel/hub must be rotated slowly while torque is applied. This action will
seat the inner and outer bearings.
3.
Using the torque wrench and socket, back off the nut until it is hand tight.
4.
While slowly rotating the wheel/hub, using the torque wrench and socket, re-torque the nut to
100 lb-ft (136 Nm). Wheel/hub must be rotated slowly when torque is applied. This action will
apply the final seat to the inner and outer bearings.
