Cast Beam Pivot Bolt Replacement Procedure
IMPORTANT: It is recommended that the trailer be unloaded
before beginning service procedures.
1.
On a level surface, support the front of the trailer with
either a kingpin stand, landing gear, or coupled to a tractor.
2.
Raise the trailer frame approximately 2" and support it
with jack stands and remove wheel chocks.
3.
At the suspensions specified ride height, place multiple
jack stands under the vehicles frame per OEM specified
locations, then lower the trailer frame onto the jack stands.
Failure to properly support the trailer
during service procedures could create
a crush hazard which, if not avoided,
could result in death or serious injury.
4.
Exhaust all air from the suspensions air bags, set the parking
brakes, and chock the wheels.
5.
Raise the trailer axle approximately 2" and support it with
jack stands and remove wheel chocks.
Failure to properly support axle during
a service procedure could create a crush
hazard which, if not avoided, could result
in death or serious injury.
6.
Remove the tires.
7.
On the roadside hangers, scribe or mark a line on the frame
bracket outlining the position of the washers on both the
inside and outside locations (Figure 1). These scribe marks
will be used for ensuring previous alignment.
8.
9.
Starting on the curbside hangers, Remove 1-1/8" inch pivot
bolt. (This is to be shipped back to SAF-HOLLAND®). Discard
the old pivot nut and old washers.
Install new pivot hardware (Figure 2).
NOTE: On the roadside hangers while the connection is in a
loose state, prior to final torque, ensure that the new
washers are indexed back in place to where you made
your scribe marks to ensure previous alignment.
Figure 1
BEFORE REMOVING ANY OF THE PIVOT BOLTS. SCRIBE AN
OUTLINE OF THE ROADSIDE WASHERS WHERE THE SWING
ALIGN IS LOCATED. THIS WILL ENSURE THAT THE SAME
ALIGNMENT WILL BE IN PLACE WHEN INSTALLING THE
REPLACEMENT PIVOT ASSEMBLY.

10. Torque the new pivot nut to a value of 550-600 ft.-lbs.
11. Clean the head of the bolt and add a white paint dot to
indicate a change has been made.
12. Reinstall the tires.
13. Repeat this process for the pivot assembly hardware on
the curbside of the suspension.
14. Lower the axle and tires onto the ground.
15. Repeat this procedure for the other suspensions affected.
16. Raise trailer approximately 2" and remove jack stands.
17. Air up the trailer suspension.
