SUSPENSION IDENTIFICATION

Introduction

It’s important that the proper suspension model be
chosen for the application in which it is to be used.
The Ridewell Self-Steering (RSS) 233 Suspension
series is a fully integrated, auxiliary axle suspension
system available for truck and trailer applications.

PART NO:

The RSS-233T 13K Trailer Suspension System can be
congured with either drum or disc brake axle as­semblies and an optional steering lock.

Refer to the engineering drawing for detailed infor­mation on the suspension system components and
operating parameters.

Read through the entire Installation and Service
Manual (ISM) before performing any installation or
maintenance procedures.

Identication Tag

Ridewell suspension systems can be identied by the

Part Number and Serial Number listed on the serial

identication tags.

Suspension Serial Tag

The Suspension Serial Tag (Figure 1) is aached to

the left-hand side (driver’s side) of the frame hanger.

The Part Number (233xxxx) refers to the individual
suspension system.

The nine-digit Serial Number (1xxxxxxxx) refers to
the date and order of manufacture of the suspension.

Please refer to both numbers when contacting Ride­well for customer service, replacement parts and
warranty information.

Notes on Self-Steering Option

Self-steering suspensions are designed to steer only
in the forward direction. The suspension should be

raised o the ground or locked into a non-steering
conguration during reverse travel to avoid damag-

ing the suspension.

Ridewell Suspensions strongly recommends the use
of automated systems that raise/lock the lift-axle
during reverse travel. For manual operations, Ride­well recommends the installation of a visual/audible
indicator to assist the driver.

Use caution when maneuvering in reverse with the
steering lock engaged. The driver should maintain
slow maneuvering speeds and avoid extreme turns.

Failure to lift the suspension and-or engage
the steering-lock during reverse travel can cause
component damage and void the warranty.

The ISM uses two types of service notes to provide
important safety guidelines, prevent equipment dam­age and make sure that the suspension system oper-

ates correctly. The service notes are dened as:

“NOTE”: Provides additional instructions or

procedures to complete tasks and make sure that
the suspension functions properly.

Indicates a hazardous situation or
unsafe practice that, if not avoided, could result
in equipment damage and serious injury.

Prior to Installation

INSTALLATION

Refer to the engineering drawing to conrm dimen­sional requirements and the range of ride heights
available.

Installations can vary and procedures should be

adapted for dierent vehicles, as needed.

• The Gross Axle Weight Rating (GAWR) is deter­mined by the system component with the lowest
load rating. Please consult with tire, wheel, axle
and brake manufacturers before installation to
determine the GAWR.

• If vehicle chassis modications are required, con­sult with the vehicle manufacturer to ensure that

such changes are permied.

• Welding or altering suspension components
is not permied without the express wrien
permission of Ridewell Suspensions.

Installer Responsibilities

The installer of the suspension has the sole responsi-

bility for proper aachment of the suspension system

to the vehicle chassis.

• The installer is responsible for locating the sus­pension system on the vehicle to provide the
proper load distribution.

• The installer must verify that vehicle crossmem­bers are positioned to support the suspension at
the installing location.

• It is the installer’s responsibility to determine that
axle spacing conforms to any applicable federal
and local bridge laws.

• The installer must verify that air reservoir volume
requirements are met after suspension installa­tion. Consult the vehicle manufacturer or Federal
Motor Vehicle Safety Standards (FMVSS) 121 for
more information.

• The installer must verify there is sucient clear­ance for proper functioning of the auxiliary
suspension, air springs, brake chambers, steering
components. axle (including axle to driveline)
and tires.

Mounting the suspension to the trailer frame

Refer to the engineering drawing for the range of ride
heights available as well as spacing and clearance
requirements of the suspension.

All models of the RSS-233T 13K Trailer Suspension
are shipped fully assembled. If the system is taken
apart for installation, the components must be reas­sembled with the proper torque applied (Page 3).

Weld-On Installation Procedure

Recommended locations of customer-furnished ller

plates and supporting crossmembers for the suspen­sion hangers and air spring mounting plates are
shown on the engineering drawing.

NOTE: A single air spring bridge assembly instead of

two air spring mounting plates is available on some
models of the RSS-233T 13K Trailer Suspension.

The welding method used must develop

a minimum weld tensile strength of 70,000 PSI per

AWS specications.

1. Mark the desired location for the frame hangers
and air spring mounting plates (or bridge assem-

bly) and customer-furnished ller plates on the
frame. NOTE: For proper support, a crossmember

must be located within six inches of the leading
or trailing edge of the frame hanger. Check the lo-

cation for sucient clearances in both the raised

and lowered positions of the suspension.

8. Perform nal assembly and inspection and check

the wheel toe seing (Page 5).

Failure to torque bolts/nuts of suspension

components to specications can result in failure of

the suspension and void the warranty.

Bolt-On Installation Procedure

Refer to the engineering drawing for the range of ride
heights available,spacing and clearance requirements

of the suspension and bolting paern detail.

Bolts/nuts for aaching the suspension to the ve-

hicle are supplied by the installer. Grade 8 bolts and

anged lock nuts or lock nuts with hardened washers

are recommended.

other components located within the frame rail are

not aected by drilling.

Check to make sure that wires, hoses or

2. Weld customer-furnished ller plates, as needed,

to crossmembers with ¼” llet welds down the

length of the crossmember.

3. Weld the customer-furnished ller plates for the
air spring mounting plates (or bridge assembly)
to the frame and crossmember(s), as needed.

Weld the ller plates with ¼” llet welds down

the length of the crossmember.

4. Weld the hangers to the frame/ller plates with

1/4” llet welds completely around the hangers.

Stop the welds 1/2” from the corners and edges.

5. Weld the air spring mounting plates (or bridge
assembly) to the frame/ller plates with 3/16” l­let welds all the way around the mounting plates/
bridge assembly.

6. If components have been removed for installa­tion, reinstall as shown on engineering drawing.

Torque to specications (Page 3).

7. Install/connect the air control kit (ACK) to the
suspension. Check the air system installation for
leaks and proper operation of controls (page 6).

Page 4 233T-Trailer-13K-ISM-RevC-10-19-18

Final Assembly and Inspection

1. Verify welds on hangers and air spring mount­ing plates. Verify that all suspension component

bolts/nuts are torqued to specications (Page 3).

2. Install wheels and tires.

When lowering an auxiliary axle on an
unloaded vehicle, pressure to the load air springs
must be reduced to below 10 psi.
Failure to reduce the air pressure could cause the
vehicle’s drive axles to rise from the ground and
the vehicle could roll in an unsafe manner.

3. Check that tires are inated to recommended
pressure. Check wheel hubs for proper level of
lubricant recommended by the manufacturer.

4. Lift the axle to the raised position. Check the air
system tubing and connections for leaks.

5. Check that wheels can rotate freely and that
brakes and slack adjusters are properly adjusted.

6. Raise and lower the suspension assembly (wheels
and tires installed) through the entire range of

travel. Make sure that sucient clearances for air

springs, brake chambers and other components
has been provided.

7. Check the vehicle’s reverse travel options:

7.1 Check steer lock operation.

7.2 Check automated system (if installed) to
make sure that suspension raises/locks wheels
during reverse travel.

Failure to check reverse travel operations
can result in component damage and void the
suspension warranty.

Do not lower the auxiliary axle while
the vehicle is moving in forward or reverse travel
above 10 mph.

8. Check wheel toe-in seing and adjust, if neces­sary (between 1/32” and 3/32”).

Air springs pressure regulates axle load

The load capacity of the auxiliary axle is adjusted
by increasing or decreasing the pressure to the air
springs. By applying more air, the lift axle takes on
a greater percentage of the load’s weight. The load
capacity is decreased as the air pressure decreases.

Accurate readings of the load capacity can be ob­tained by parking a loaded vehicle over a calibrat­ed scale and lowering the axle onto the scale. The
air pressure to the air springs is manually adjusted
up or down to obtain the axle load weight at vari­ous air pressures.

Do not exceed the rated load capacity of
the suspension system or other components. Ex­ceeding the capacity can cause component failure
and void the warranty.

Check Wheel Toe Seing

1. Deate the air springs.

2. Lift the axle enough for tires to rotate freely. Sup­port with jack stands to ensure axle is level.

3. Position tires to point straight ahead. Spin each
tire. Use a piece of chalk to mark a line on the
center tread all the way around the tire.

4. Use the centerline mark to measure the distance
from the front of the tire to the frame. Measure
the distance from the back of the tire to the frame.

5. Subtract the front of the tire distance from the

rear distance to obtain the wheel toe seing.

Adjust Wheel Toe

1. Loosen clamps on both ends of the tie rod. Twist
the tie rod forward/backward to move the front of
the tire towards or away from the frame.

2. Continue rotating the tie rod until the proper toe-

in seing is achieved.

3. Torque tie-rod clamps to 60-80 ft-lb (81-108 N-m).

Wheel Toe Setting

Wheel toe is the relationship of the distance between
the front of the tires and the distance between the
rear of the tires on the same axle.

When the front distance is less than the rear distance,
the wheels are in a “toe-in” (positive toe) condition.

The correct seing for the RSS-233 suspension should

be toe-in between 1/32” and 3/32”.

Install air system components

Connect the load and lift air springs and an air con­trol kit to the air system (Figure 2).

The air control kit (ACK) consists of a pressure
regulator with a gauge connected to an air valve
controlled by an electric switch or manual knob. The
ACK allows the operator to control the air spring
pressure so that the auxiliary axle can support dier­ent loads.

Ridewell has a number of manual/electric ACK

congurations available. Installation will vary by the
type of conguration.

The installer is responsible for making sure
that air system requirements comply with the appro­priate Federal Motor Vehicle Safety Standards.
