FIFTH WHEEL AREA INSPECTION
The fifth wheel area must be kept clean and free of dirt and foreign materials. This
includes the area between the kingpin plate and the body of the trailer where the
conveyor chains and flaps travel. Buildup of snow, ice or other foreign materials can
cause binding or other serious damage if allowed to remain in this area. Any binding can
place excess stress on the front shaft, which can result in any of the following:
•The shaft to bend or break
•The bearings or adjustment mechanisms to be damaged
•The chain to stretch excessively, resulting in premature failure
Daily inspect the kingpin and kingpin plate for the following:
•Wear, cracks or other damage
•Damaged or missing parts
•Bent belt return slides (Figure 2); these can be bent during normal operation and must
be straightened before use
Keep the fifth wheel plate lubricated in accordance with the tractor manufacturer’s
recommendations.

ADJUSTING AND LUBRICATING
THE CONVEYOR SYSTEM
CONVEYOR CHAIN ADJUSTMENT
It is normal for the chain to "stretch" as it is used. The amount of "stretch" will be greater
when the chain is new as the pins get seated against the barrel of the chain. It is important
to keep the chain adjusted to prolong the life of the chain. The chain should be operated
within the two pointers on the chain adjustment gauge (Figure 3), which is located on the
roadside of the trailer between the front of the suspension and the center of the trailer.

Jun 2014 Rev
ADJUSTING THE CHAIN
1. Loosen the jam nut in the chain adjustment assembly (Figure 4).
2. Tighten the adjuster bolt, alternating sides so that one side of the shaft does exceed
1/4" ahead of the opposite side, until the chain is between the two pointers on the
chain adjustment gauge (Figure 3).
3. If the chain adjustment assembly is out of adjustment and the chain is not within the
two pointers, you will have to remove some chain links. (Procedure to follow)
4. Measure the distance from front of trailer to the shaft on each side and adjust so that
there is no more than 1/8" difference.
5. Tighten the jam nut.
REMOVING CHAIN LINKS
1. Rotate the conveyor until there is a master pin 3 - 5 feet in front of the suspension.
The master pin can be identified by the head of the pin (Figure 5).
2. Loosen the jam nut in the chain adjustment assembly (Figure 4).
3. Loosen the adjuster bolt, alternating sides so that one side of shaft does not exceed
1/4" behind the opposite side, until the sprocket teeth are just in front of the trailer
floor.
4. Verify that the shaft can rotate without the sprockets hitting the trailer floor.
5. In front of the suspension connect a Come-Along into the chain links of each chain
with the master pin centered between the connection points.
6. Pull up all of the slack chain (Figure 6).
7. Grind the weld off of the master pins.
8. Drive out the pin using a punch.
9. Pull up the slack to determine how much of the chain to remove (Figure 7). You may
have to remove links from both sides of the split. You should remove links so that
you do not have more than 5 links between flaps.
10. Grind off the head of the pin you need to remove (Figure 8).
11. Drive out the pin using a punch.
12. Connect the chain using a new pin and cotter pin.
13. Weld the chain pins using the following procedure.
14. Remove the Come-Along from each chain.
15. Adjust the chain using the previous procedure.
WELDING CHAIN PINS
The pin must be secure and should not be able to freely rotate within the link as this can
cause accelerated wear and result in failure of the pin.
1. Place the ground clamp from the welder on the chain itself near the link to be welded.
Placing the ground on the body of the trailer will not allow enough current to pass
through the link to obtain a sufficient weld.
2. Weld the pin on the "trailing" edge of the pin. Weld between the pin and the link, not
just the pin and the cotter pin (Figure 9).

3. No weld is required on the opposite side of the chain where the head of the pin meets
the link (Figure 5).

CONVEYOR CHAIN LUBRICATION
The conveyor chain must be inspected regularly and lubricated using a high quality oil.
Do not use grease. Any type of lubricant may be used depending on products hauled and
individual preference. A good general purpose lubricant is chain and cable fluid, which
has penetrating qualities as well as dust repellent. Use Table 1 to determine which grade
of lubricant to use based upon the operating temperature.

How often the chains need lubrication is dependent upon the amount of use and the type
of product carried.
•Under daily use or in harsh environments, daily inspection is required. Lubricate as
needed.
•Under all other uses, weekly inspection should be sufficient. Lubricate as needed.
•If a food-grade lubricant is used, you may need to apply it more often. It is your
responsibility to determine how often lubrication is required.
!WARNING
Remember, proper lubrication can extend chain life, reduce down time and save you
money.
BEARINGS AND SPROCKETS
The bearings on the front and rear conveyor shafts must be inspected and lubricated at
regular intervals using an NLGI Grade 2 general-purpose grease. As with chain
lubrication, the amount of lubrication is dependent upon the amount of use.
•Under daily use, daily inspection is required. Lubricate as needed.
•Under all other uses, weekly inspection should be sufficient. Lubricate as needed.
•Inspect sprockets for excessive wear or damage.
!WARNING
PLANETARY GEARBOX
When using the planetary gearbox under normal temperature ranges between 0-120 °F,
the gearbox is to be half full of SAE 80/90 oil. Use the lower of the two plugs to check
the level of the oil. Oil is to be changed after the first 50 hours of operation with
subsequent changes every 1000 hours or yearly, whichever comes first.
Attempting to lubricate the chains while they are in motion
can result in serious bodily injury or death. Stay clear of the
chains while they are in motion. Position the chains and
completely disable the hydraulic system before doing any
maintenance.
Attempting to lubricate the bearings while the shaft is
rotating can result in serious bodily injury or death. Stay
clear of the bearings while they are rotating. Completely
disable the hydraulic system before doing any maintenance
on the bearings.
NOTE
There is absolutely no warranty, expressed or implied, on the chain or
drive system if the system is not maintained properly, is misused or is
overloaded. This includes, but is not limited to the hauling of corrosive
materials such as fertilizer, sludge, brewer’s mash or corn gluten.

LUBRICATION OF THE DOOR(S)
Door hinges and bearings must be lubricated regularly, especially if the trailer has been
operated or stored for an extended period of time in a humid or wet environment.
Corrosion can lead to the failure of door hinges if they are not maintained properly. As a
general rule with the rear doors, as with the entire trailer, “if it moves, lubricate it.” Use a
NLGI Grade 2 general-purpose grease on all shafts and grease zerks.
The seals on most doors should have silicone grease or spray-on lubricant applied to them
once every three months. This will help them last longer and will help them provide a
better seal. During cold, damp weather or under heavy use, apply the grease more
frequently.
CARE OF THE PLASTIC LINER
HIGH MOLECULAR WEIGHT (HWM) AND
ULTRA-HIGH MOLECULAR WEIGHT (UHMW) LINER
The plastic liner under the chain (and on the slopes, if applicable) must be inspected for
damage and wear. Replace the liner if it is worn through at any spot. If any foreign
material should become lodged between the liner and the body of the trailer, remove it by
blowing or vacuuming it out.
!
CAUTION
!WARNING
Use eye protection when using air to blow material from
underneath the liner to help prevent injuries from flying
particles.
Getting inside the trailer with the door(s) closed or the
hydraulic system energized can result in serious injury or
death. Open door(s) and disable all hydraulic systems
before entering the trailer.

COATING CARE AND CORROSION PREVENTION
Your Eagle Bridge™ trailer is coated with a high-performance polyurethane paint. This
paint is designed to give you durable performance in the rugged environments
encountered by your trailer.
The best way to preserve the finish on your trailer and help prevent corrosion is to wash it
regularly, especially after it has been used around road salt or other ice melting agents,
road oil or tar, or any other potentially corrosive material. Use warm water with a mild
detergent and allow the trailer to air dry. Use of abrasive or caustic cleaning agents will
void the paint warranty. Hauling corrosive products such as salts and fertilizers will also
void the paint warranty.
Small nicks or chips in the paint can occur with normal use. Any chips or scratches in
the finish should be repaired with matching touch-up paint. This is especially important
for carbon steel trailers, as even small areas of bare metal can corrode quickly. The cost
of repairing any chips is the responsibility of the owner.
Removal or disrepair of mud flaps on either the tractor or the trailer will void the paint
warranty. Frequent use of the trailer on gravel roads will also void the warranty.
If your trailer has aluminum wheels, you should clean them regularly with mild detergent
and water to prevent corrosion. Use a non-abrasive, non-acidic cleanser to remove heavy
build-up when necessary. Do not use abrasive metal polishes or scouring pads.
STAINLESS STEEL BODIES
Trailers with stainless steel bodies require the same care as painted trailers. Regular
washings to remove road grime and remnant corrosive material will help maintain the
finish and help prevent corrosion. Use warm water with a mild detergent and allow the
trailer to air dry. Use of abrasive cleaning agents will dull and scratch the finish. Use of
carbon steel utensils will result in surface contamination.
It is particularly important to rinse off the trailer after hauling any material containing
chlorides as prolonged contact with chlorides may dull the finish and leave it subject to
pitting.
Carbon contamination of stainless steel will cause localized rust spots. The breakdown of
the carbon on the surface of stainless steel does not affect the structural integrity of the
trailer.

CLEANING THE INTERIOR
If product accumulates underneath the chain and flaps, it can usually be removed by
lifting each flap and vacuuming, sweeping or blowing the material out. Under no
circumstances should you get into the trailer with the conveyor system running or
enabled (Figure 14). For your safety, completely disable the hydraulic system
before entering the trailer (Figures 15 and 16).
