1. Inspect the slack adjuster for structural damage. Replace the slack adjuster if needed.

2. Inspect the slack adjuster boot for cuts or tears. If the boot is damaged, replace it (see Fig. 10).

2.1 Remove the two clevis pins.

2.2 Rotate the worm shaft adjusting hexnut counterclockwise to move the link away from the clevis. About 45 lbf·ft (60 N·m) is needed. You will hear a clicking sound. Remove the old boot from the link.

2.3 Install a new boot on the link, heavy section down. Be careful not to damage the boot.

2.4 Seat the boot so that the bottom of the boot is in the boot insert, and the top is in the groove of the link.

2.5 Rotate the adjusting hexnut clockwise until the 1/4-inch hole in the clevis lines up with the hole in the link.

Install the 1/4-inch clevis pin and the cotter pin.

2.6 Tap the clevis upward or downward until the large hole in the slack adjuster lines up with one in the clevis.

1. Apply the parking brakes and chock the tires.

2. Make sure the refrigerant compressor drive belt is not damaged, and is correctly tensioned. Also check the tightness of the compressor mounting fasteners. For instructions and torque values, see Group 01 of the Business Class® Trucks

3. Using a feeler gauge, check for correct clutch clearance. For instructions, see Group 83 in the Business Class® Trucks Service Manual.

4. Inspect the compressor clutch coil wire. Check the connector for damage or looseness. Replace the wire if it is damaged.

5. Check for broken, burst, or cut hoses. Also check for loose fittings on all parts.

WARNING: Wear eye protection when using compressed air or high-pressure water to clean parts, as permanent harm to eyes could result from flying debris.

6. Check for a build-up of road debris on the condenser fins. Using a whiskbroom and air pressure, or a spray of soapy water, carefully clean off the condenser; be careful not to bend the fins.

CAUTION: Failure to retorque the U-bolt nuts could result in spring breakage and abnormal tire wear.

Fontaine: Use a multipurpose extreme pressure (EP) chassis grease, and lubricate all moving parts on the fifth wheel. When lubricating the top plate at the grease fittings for the bracket bearing area, tilt the top plate forward and backward to evenly distribute the grease. Using a pry tool, separate the jaw and wedge and lubricate the serrations using a brush to distribute the grease. On slide-mount applications, lubricate the slide rail and tapered wedges for smooth operation.

Once the fifth wheel’s moving parts are lubricated, apply a liberal coating of grease to the top plate and the trailer kingpin plate.

Holland: Lubricate all moving parts with oil or a light grease. Lubricate the fifth wheel top plate with a waterproof or multipurpose chassis grease.

Once the moving parts of the fifth wheel are lubricated, apply a heavy coat of grease to the top plate by direct application. On slide-mount applications, lubricate the baseplate rails and the plungers for smooth operation.;
