DCA-600SSV —TRAILER MAINTENANCE

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.

CAUTION - EYESIGHT HAZARD

ALWAYS wear safety glasses when removing or installing force fitted parts. Failure to comply may result in serious injury.

CAUTION - REPAIRINGTRAILER WHEELS

DO NOT attempt to repair or modify a wheel. DO NOT install in inner tube to correct a leak through the rim. If the rim is cracked, the air pressure in the inner

tube may cause pieces of the rim to explode (break off) with great force and cause serious eye or bodily injury.

Tire 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 16 (Tire Wear Troubleshooting) will help pinpoint the causes and solutions of tire wear problems.

ALWAYS wear safety glasses

NOTEwhen removing or installing force fitted parts. Failure to comply may result in serious injury.

Suspension

Torsion axle systems, the suspension takes place inside the square tube which is filled with highly resilient rubber. It attaches directly to the trailer frame using brackets which are an integral part of the axle assembly (See Figure 70 below).

Visually inspect the mounting hardware every 6,000 miles for signs of excessive wear, elongation of bolt holes, and loosening of fasteners. Replace all damaged parts immediately. Torque torsion axle mounting hardware as recommended by manufactuer.
