WELDING
When welding, be sure to wear all personal
protective equipment for face and eyes, and have
adequate ventilation. When welding, protect air
springs from weld spatter and grinder sparks. Do not
attach “ground” connection air spring support.
Welding Specs
To perform the welding, the welder must be qualified
for 2G position per ANSI / AWS D1.1-94 Section 5
Part C “Welder Qualification”.
All welds must be performed in a flat, horizontal
position. Suspension components and their mating
parts must be free of dirt, scale, paint, grease and
moisture.
Any deviation from these welding specs must
be reviewed and approved by TUTHILL Transport
Technologies Engineering in writing prior to
commencement of any work.

NOTE
Normally, prior to any major repairs
or maintenance procedure, contacts
between companies have been made,
and all necessary information to
perform the maintenance has been
exchanged. However, the following
general steps are listed in the interest
of all involved and should be included
in an overall maintenance program.

AIR SUPPLY
Check that supply air pressures and flow are
adequate to supply system. Check height con-
trol valve and linkages to ensure unit is operat-
ing at correct ride height.
AIR SPRINGS
The air springs are equipped with internal bump
stops for safety. However, do not operate the
loaded unit on the bump stops for any extend-
ed periods of time, except to move the unit to a
repair facility.
Please ensure that you are matching the correct
air spring to the suspension model.
TORQUE
To comply with warranty and safety require-
ments, check torque values during pre-delivery
inspection, after 1,600 kms (1,000 miles) of
operation and each additional 80,000 kms
(50,000 miles) or annually, whichever is first.
M-3
PERSONAL LIFTING
Practice safe lifting procedures. Consider size,
shape, and weight of assemblies. Obtain help
or the assistance of a crane when lifting heavy
assemblies. Make sure the path of travel is
clear.
OVERLOADING
Overloading of the suspension system or its
components is the practice of transporting car-
gos that surpass the specified vehicle’s ratings.
Overloading can cause component failure,
resulting in accidents and injuries.

U-BOLT
1. U-BOLT installation and torquing should be
done only after completion of axle weld. Be
sure to provide sufficient cooling time
before applying torque wrench.
2. Do not apply any lubricants to the u-bolts.
3. Be sure that the u-bolt spacer is located
centrally under the u-bolt.
4. Snug u-bolts evenly before applying torque.
5. Torque u-bolts by following 3 step
sequence shown. Deviation from this
sequence could result in an improperly
installed clamp assembly which could
cause damage to the axle connection.

AIR CONTROL
M-5
HEIGHT CONTROL VALVE
Height Control Valves regulate the mounting
height (ride height) of the suspension.
1. One height control valve (HCV) is used,
regardless of the number of axles. The air
springs on each side of the trailer are
connected by 9.5 mm (3/8”) minimum
diameter tubing (customer supplied). Care
must be taken to ensure the HCV is
positioned as shown on the installation
drawing for the model being installed.
2. Care must be taken when installing HCV to
ensure correct ride height is attained.
3. To set/adjust ride height, simply assemble
the linkage to the desired length to attain
the required ride height.
For maximum strength, it is recommended
that the linkage set screws 16 mm (5/8") be
placed in the end holes of both links.
4. This suspension uses a height control valve
(HCV) which utilizes a short delay.
5. Ensure that the air springs and all valves are
plumbed as shown.
6. The pressure protection valve (PPV) and
filter are installed between the HCV and the
air reservoir.
7. Using customer supplied materials, connect
the HCV to all air springs using 9.5 mm
(3/8”) diameter tubing. As with any pressure
system, check for leaks and
eliminate leakage, if present.

ALIGNMENT
1. Release the brake system and pull the
trailer forwards and backwards several
times in a straight line to free the suspen-
sion from binding and tension.
NOTE: This procedure must be performed
on a smooth level surface.
2. For best results, the use of axle extensions
and a “BAZOOKA” type king pin post, or
a suitable optical alignment device are
recommended.
3. NOTE: Prior to commencing alignment,
ensure that the trailing beam is installed to
centre line of hanger. Align the front axle
with the king pin as shown.
4. Align the remaining axles to the front axle as
shown.
5. Torque the hanger clamp bolts if
REY-ALIGNTM or if huck bolted, weld the
alignment washers as shown.
6. (REY-ALIGNTM feature) torque 22 mm (7/8”)
alignment clamp bolt to 815 Nm (600 ft lbs)
using only a torque wrench.
NOTE: 1) Refer to page M-14 for details.
2) Run nut up very slowly.
7. Torque the adjustment shaft (REY-ALIGNTM
feature) clockwise to 80 Nm (60 ft lbs) or, if
Huck®Bolt, weld the alignment washers as
shown on the right.
8. (If replacing Huck Bolted) torque 28 mm
(1-1/8”) replacement pivot bolt to 1110Nm
(820 ft lbs). Run nut up very slowly.
9. Optional: Weld along top of “TAB” to secure
alignment in position.
NOTE: By removing welds carefully, you
should be able to re-align up to 3 or 4
times with minimal or no cleaning.
10. Verify that torque is correct on all fasteners.
11. After initial 1,600 kms (1,000 miles), the
alignment should be re-checked and
corrected if necessary, torque on the clamp
nuts should also be checked.

TROUBLE SHOOTING GUIDE
M-8
ROUGH RIDE
Check the suspension ride height. Be sure the
suspension is operating at the proper height.
If too high, over inflation of the bags will be
evident. Ensure the opposite is not occurring
(no air in air springs) and correct as required.
LOOSE PIVOT CONNECTION
A properly torqued pivot connection is the key
to a long life of a suspension. It is crucial
to ensure sufficient clamp load through the
bushing to prevent premature failure. With Rey-
AlignTM hangers, ensure all components are
included and that proper installation/torque
procedures are followed.
SHOCKS
Shocks may fail due to over extension. Check
the mounting bolts to be sure no damage to the
mounts has occurred. Shock replacement
must be done with shocks recommended
by Reyco or shock manufacturer. Leaking
(dripping) shocks need to be replaced. Shocks
with a slight mist of oil on them need to be
checked, not necessarily replaced. Ensure that
the correct shock has been installed.

FASTENERS
Loose fasteners need immediate attention.
Check components for wear and be sure holes
are not worn or egg shaped. When replacing,
be sure threads are clean, lubricated and not
deformed. Consult the maintenance section for
the correct torque specifications and replace
any fastener which is damaged or will not stay
torqued. If bolts need to be replaced, be sure to
use the same grade of fastener.

AIR
1. Bags won’t inflate (A) Check air supply at
the height control valve. If supply is good,
(B) check to see if air is going thru the valve
when it is actuated. A majority of problems
are found at this point. If air is going thru
the valve, (C) check for blockage or a
pinched airline to the air bags.
2. Be sure that height control valve is set
properly.
TRAILER NOT PULLING STRAIGHT
Check alignment. Recheck alignment at annual
inspections. Ensure suspension is square to
the axles.
IRREGULAR TIRE WEAR
Check the alignment. Recheck alignment at
annual inspections.

transit or handling before inserting the pivot shaft (part number 23948-01) through the sleeve.
2) Inspect the threads on the pivot shaft to make certain they are clean and debris free from transit or
handling before running up the nut.
