Figure 4-17: Stud Tightening Sequence
4. Install the flange nut and tighten to 50 foot-pounds
using the sequence in Figure 4-17. Then tighten to
full torque of 500 to 550 foot-pounds.
5. Torque will drop after the first 50 to 100 miles of
operation. Check the nuts for proper torque after this
interval and retighten them.
Use a torque wrench to assure proper torque.
Insufficient torque can cause stud breakage and
damage wheel pilots. Overtorque can overstress
the studs and strip the threads.

WARNING
Winches
Inspect the winch cable before and after every usage. If
frayed wires, nicks, kinks, worn spots, breaks or any
other sign of deterioration or damage is found, immediate
replacement is mandatory before further usage. If the
trailer is going to be out in the weather for any length of
time, it is advisable to oil the winch cable to prevent
untimely rusting and deterioration of the cable. See
Table 4-1 for lubrication specifications.
Inspect the winch mechanism thoroughly each week to
insure safe, efficient operation.
Do not handle the winch cable when the winch is
in the engage position. Hands or clothing could
get caught in the cable and be pulled into the
spool causing serious personal injury.
