Fifth Wheel Handle Adjustment

Figure 1 If the handle remains in the upright position after uncoupling, (shown as upper handle in figure), the nuts are adjusted too tightly. Upon uncoupling, the handle should fall freely to the bottom of the slot (shown as lower handle in figure), allowing the handle to move inward

Figure 2 If the handle rests on the top of the slow when fully coupled (shown as upper handle in figure), then the nuts are too tight. When fully coupled, the handle should rest at the bottom of the slot (shown as lower handle in figure).

Note: It is necessary to use two wrenches to loosen/secure the standard and

jam nuts. Proper adjustment of the nuts will be achieved by following these guidelines:

1) The standard nut should be fully tightened onto the handle's

capscrew. 2) Tighten the jam nut until it bottoms out on the end of the

capscrew. 3) Complete tightening by locking the standard nut against the jam

nut. Recheck handle movement for proper adjustment.

Air Jam Eye INSTALLATION AND ADJUSTMENT INSTRUCTIONS

1. With Jam Eye Shank already installed in the shock housing, slide the pushrod, threaded

end first, over the top of the eye and into the tubular shank. 2. Install the shoe by placing it into the eye with the contact surface facing to one side,

rotate the shoe 90 º so its contact surface faces forward and the hole for the pushrod is to the rear. Check to insure the shoe will slide fore and aft along the inside of the eye.

3. Install the pushrod into the shoe, making sure to line up the holes. Drive the roll pin into

the shoe and through the pushrod. 4. Slip the threaded end of the pushrod through the cap on the shank nut and install a jam

nut and coupling nut. Thread both nuts on as far as possible to draw the shoe to the rearmost position in the eye.

5. Install a service air chamber with a s 2" pushrod length with a jam nut threaded onto its

pushrod. Torque air chamber mounting nuts to 100 ft/lbs. 6. With a 5/8" open-end wrench pry against the jam nut on the air chamber pushrod to pull

the pushrod out 3/16" to 1/4". Thread the coupling nut part way onto the air chamber pushrod to couple ti with the pushrod and shoe.

7. Loosen the jam nut against the cap of the shank nut to allow the pushrod and shoe to

travel forward when air pressure is applied.

Air Jam Eye Installation and Adjustment Continued

8. Place a 2" diameter rod into the eye and apply air to the service chamber. DO NOT PLACE FINGERS IN THE AREA OF THE EYE AND SHOE OR AREA OF COUPLING NUT WHEN APPLYING AIR TO THE SERVICE CHAMBER.

9. With the shoe contacting the 2" diameter rod, adjust the jam nut on the pushrod until it

contacts the cap on the shank nut. Tighten the coupling nut and the two jam nuts, jamming them together.

10. Release the air pressure and reapply to recheck the adjustment. NOTE: After tightening shank nut to adjust shock housing, re-adjust shoe and stop using step 4 through 10.

Recommended Welding Locations ALL TRAILER AXLES

The correct positioning of spring seat attachment welds is very important to the structural integrity and load carrying characteristics of the axle beam. It is important to note that different axle styles have different requirements. Attached spring seats to the beam must be a controlled manufacturing process. Both the seat and the axle must be properly positioned by assembly fixtures and then welded in place. Please refer to the following instructions for properly locating spring seats on Rockwell trailer axles. Round Axles On round axles, the spring seats normally have full contact with the axle beam and very little vertical load is transmitted to the attachment weld. These welds carry the torsional loads of the suspense and resist torsional braking loads. For proper assembly, seats must be in full contact with the beam, be parallel with each other, and be correctly located in relationship to the top of the axle beam. Important On some suspensions, in particular trailing arm air rides and rubber sphere types, torsional loads are transmitted through the welds and into the axle during articulation. These applications require special care when establishing welding locations. Contact the Rockwell Trailer Axle Application Department for welding recommendations for each individual application. Rectangular, Square and Shaped Axles

Axle shapes, other than round, do not always allow full contact of the spring seat to the axle beam. This condition exists even though the seats are parallel to each other and properly positioned. This condition means that parts of the vertical load, as well as the

braking and/or suspension torsional loads, must be absorbed by the attachment welds.

TRAILER AXLE INSTALLATION




(800) 547-6792 FAX: (503) 335-2171


Trailer Axle Installation Instructions The trailer axles must be installed in the vehicle so that they are parallel to the rear axle of the tractor when the vehicle is moving forward in a straight line. The center of the fifth wheel king pin and the center of the axles must be installed at the center of the trailer floor. Figure 1 Use the following procedures to check the alignment of trailer axles: Single Axle Trailers 1) Raise or lower the fifth wheel to put the

trailer in a level position. 2) Remove the outer wheels or the outer tires

and rims, depending on the wheel equipment. (Figure 1)

3) Remove any parts from under the chassis that can interrupt measuring the distances between the king pin and the ends of the axle.

4) Load the trailer to its rated capacity with the load correctly arranged.

5) Attach a steel measuring tape to a hook and the hook over the king pin. Measure the distances "A" and "B" from the king pin to the ends of the axle. The differences between the A and B measurements must not exceed 1/8" (3.2 mm).

Tandem Axle Trailers 1) Move the trailer forward and backward over a

level floor, two or three times with the last movement forward, to permit the suspension to become correctly aligned to center the front and rear wheel tracks.

2) Raise or lower the fifth wheel to put the trailer in level position.

3) Remove the outer wheels or outer tires and rims of the forward axle only, Figure 2.

4) Remove any parts from under the chassis that can interrupt measuring the distances between the king pin and the ends of the forward axle.

5) Load the trailer to its rated capacity with the load correctly arranged.

6) Attach a steel measuring tape to a hook and the hook over the king pin. Measure the distances "A" and "B" from the king pin to the ends of the forward axle. The differences between the A and B measurements must not exceed 1/8" (3.2 mm).

7) Measure the distance "C" and "D" between the front and rear axle centers. The differences between the C and D measurements must not exceed 1/16" (1.6 mm).

This small gauge can help you make the "C" and "D" measurements between the axle centers. The gauge can be made of drill rod and must be rigid and true. The pointer arms of the gauge must be parallel and held at the same height. How To Correct The Alignment Of Axles To correct the alignment measurements that are not within the limits, inspect the suspension for worn, broken or loose parts. Adjustments to the suspension, and the replacement of worn or broken parts, must be made to put the axles into alignment. Carefully follow the service instructions made available by the trailer or suspension manufacturer when you work on this component. The limits of 1/16" (1.6 mm) and 1/8" (3.2 mm) are the maximum limits for correct alignment of the axles. These small limits make accurate measurements.
