DCA-20SPX —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.

TireWear/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 13 (Tire Wear Troubleshooting) will help pinpoint the causes and solutions of tire wear problems.

Suspension

The leaf suspension springs and associated components (Figure 45) should be visually inspected every 6,000 miles for signs of excessive wear, elongation of bolt holes, and loosening of fasteners. Replace all damaged parts (suspension) immediately. Torqued suspension components as detailed in Table 14.
