Installation Instructions
13. SwingAlign Axle Alignment
13.1 Alignment Preparation
1. Pull the trailer in a straight line for a sufficient distance
to ensure that there are no binds in the suspension.
2. Disengage the trailer parking brakes and make sure the
trailer is empty.
3. Manually measure or use an optical device specifically
designed for alignment measuring to determine the following:
a. Measure the distance from the king pin to the centerline
of the front axle spindles. It is recommended that the
spindle extensions be utilized.
b. Dimensions A and B
(Figure 20)
MUST be equal to
within 1/8" (3 mm).
c. Measure the distance from the centerline of the front axle
spindles to the centerline of the rear axle spindles.
d. Dimensions C and D
(Figure 20)
MUST be equal to
within 1/16" (1 mm).
13.2 Alignment Instructions
1. Using the measurements per Section 13.1 Step 3, align
each axle. Align by rotating the alignment bolt head
using a 1-3/8" socket wrench on the front face of the
road-side frame bracket clockwise to move axle forward
(A arrows);
counterclockwise to move axle rearward
(B arrows)
(Figure 21)
. Approximately 250 ft.-lbs.
(339 N•m) will be required.
IMPORTANT:
DO NOT loosen the pivot bolts.
IMPORTANT:
Two (2) scribe lines on the side of the frame
bracket indicate maximum adjustment for axle
alignment. If the edge of the visible washer
touches either scribe line, the SwingAlign
axle alignment adjustment is “out of stroke.”
Inspect and repair trailer components as
necessary and realign
(Figure 22)
.
IMPORTANT:
The SwingAlign design maintains proper
alignment without welding or without
loosening of the pivot connection. DO NOT
weld alignment bolt or pivot bolts
(Figure 22)
.
14. Brake Adjustment Instructions
Brakes should be adjusted per axle and brake manufacturer’s
specifications.
For CBX/CB Suspensions with Drum Brake Systems refer to
SAF-HOLLAND Drum Brake Service Manual, XL-TA10006OM.
For CBX Suspension with Disc Brake Systems refer to
SAF-HOLLAND Disc Brake Service Manual, XL-SA10059OM.
