Lug Nut Torque Requirements
It is extremely important to apply and maintain proper wheel
mounting torque on the trailer. Be sure to use only the fasteners
matched to the cone angle of the wheel. Proper procedure for
attachment of the wheels is as follows:
1. Start all wheel lug nuts by hand.
2. Torque all lug nuts in sequence. See Figure 36. DO NOT
torque the wheel lug nuts all the way down. Tighten each lug
nut in 3 separate passes as defined by Tables 6 and 9.
NEVER!
use an pneumatic air gun
to tighten wheel lug nuts.
3. After first road use, retorque all lug nuts in sequence. Check
all wheel lug nuts periodically.
NOTE
Tires/Wheels/Lug Nuts
Tires and wheels are a very important and critical
components of the trailer. When specifying or replacing the
trailer wheels it is important the wheels, tires, and axle are
properly matched.
ST-45HRM CE CONCRETE PUMP— TRAILER SAFETY GUIDELINES
DO NOT attempt to repair or modify a wheel.
DO NOT install an inter-tube to correct a
leak through the rim. If
the rim is cracked, the
air pressure in the
inter-tube may cause pieces of the rim to
explode (break-off) with great force and
can cause serious eye or bodily injury.
ALWAYS
wear safety glasses when
removing or installing force fitted
parts. Failure to comply may result in
serious injury.
CAUTION
Tires Wear/Inflation
Tire inflation pressure is the most important
factor in tire life. Pressure should be
checked cold before operation. DO NOT
bleed air from tires when they are hot.
Check inflation pressure weekly during
use to insure the maximum tire life and
tread wear.
Table 5 (Tire Wear Troubleshooting) will help
pinpoint the causes and solutions of tire wear
problems.
