10.2.1.17 RIDEWELL TORQUE REQUIREMENTS
10.2.1.18 RIDEWELL AXLE ALIGNMENT
The RAR-260 suspension is equipped with the Speed Set® alignment feature for simple, manual
alignment of the axles. Depending on the suspension model, slots are provided in either the
pivot connection.
1. Prior to alignment, position the suspension beams so that the pivot bolts are centered in the
alignment slots. See Figure 1a.
2. Align the forward axle to the center of the kingpin to within ± 1/8”.
See Figure 2.
3. Alignment procedure:
a. Loosen the pivot nut.
b. Move beam in the direction of desired axle movement. Use a 1/2’’ shank breaker
bar inserted into the square hole in the adjuster plate. See Figure 1b. Ensure that
both inboard alignment washer and outboard adjuster plate have moved in unison. It
is important that the bushing is not skewed in the hanger prior to tightening.
c. Snug the pivot fasteners and re-check alignment measurements. Adjust if neces-
sary.
Note: Torque the pivot bolt with the suspension at ride height to prevent pre-stressing
the rubber pivot bushing. Note: It is imperative that the pivot fasteners be
properly torqued prior to placing the trailer into service. Failure to torque the
pivot fasteners will lead to slippage of the pivot joint, causing
rapid wear of the components and ultimately leading
to catastrophic failure of the suspension. Warranty coverage of the suspension is void i
f the pivot fasteners are not properly torqued.
e. Welding alignment washers to the hanger sidewalls of hanger mount suspensions
is not required or recommended.
See Figure 2.
4. In general, small alignment changes can be made on one side (left beam or right
ence from one side to the other (i.e. 1/2 the difference forward at one beam, 1/2 the
