Tire Maintenance
Wheel Torque Requirements
At least once each week, use an accurate tire
pressure gage to check the air pressure in all
four trailer tires. Inflate to the pressure
recommended by the tire manufacturer (located
on the tire).
It is extremely important to apply and maintain
proper wheel mounting torque on your axle.
Wheel nuts should be retorqued after 50 miles
and 100 miles and periodically there after.
Low or uneven tire pressures will not properly
support a loaded trailer and could lead to
premature tire wear.
When replacing tires, it is important to use a tire
of appropriate size and load rating (75D-15).
Failure to maintain proper torque on the lug
nuts may result in the wheel shearing off of the
trailer, possibly causing an accident and
seriously damaging the equipment.
The tightening of the lug nuts should be torqued
in the sequence above.
Lug nuts should be torqued in stages:
Stage 1 Stage 2 Stage 3
25 Ft-Lbs 60 Ft-Lbs 100 Ft-Lbs
This procedure should be followed after each
time the tire is removed.
Lubrication (every 6 months)
Lubricate the following parts with clean motor oil
or wheel bearing grease
where shown.
For additional brake operating and service instructions, refer to the Surge Brake Actuator Manual
provided with the trailer.
NOTE:
Be sure that no grease is applied to brake pad.
