Bolt Torque Specications
TIGHTENING WHEEL NUTS: Torque 9/16”-18 lug nuts on wheels to 170 ft-lbs during initial operation of the header wagon. Check
for proper torque after every 10 hours of use. Failure to do so may damage wheel nut seats. Once seats are damaged it will become
impossible to keep nuts tight.
Always tighten hardware to these values unless a dierent torque or tightening procedure is listed for specic application. Fasteners must
always be replaced with the same grade as specied in the manual parts list. Always use the proper tool for tightening hardware. Make
sure fastener threads are clean and you start thread engagement properly. Use these values when tightening all bolts and nuts with
the exception of wheel nuts.

Operations/Maintenance
DANGER: BE CERTAIN THAT ALL POWER IS SHUT OFF BEFORE SERVICING THE 4 WHEEL STEER HEADER TRANSPORT.
Before the Header Transport is Put into Service:
• Has the Slow-Moving Vehicle sign been properly positioned at the rear of the header transport?
• Have all danger, warning, caution and important signs on the equipment been read and understood? If employees or others use or
are near this equipment, make sure that they also have read and understood all danger, warning, caution and
important signs on the equipment and have also read the operator’s manual.
• Are all braces, bolts, nuts, studs and lug nuts properly fastened?
• Has the header transport been properly fastened to the towing unit? Use a good quality hitch pin with clip and safety chains.
• Are the rear amber extremity lights properly positioned? Extend lights within 16”of the left and right extremities of the header.
• Check alignment of tires yearly. Adjust the push pull rod to realign the tires if needed.
Safety Chain User Instructions
• Secure the safety chain by looping it around the tongue support located on the underside of the hitch tongue and connect to the
towing machine’s attaching bar.
• Do not allow more slack than necessary for articulation.
• Do not use an intermediate support as the attaching point.
• Store the safety chain by securing it around the tongue.
• Replace the safety chain if one or more links or end ttings are broken, stretched or otherwise damaged or deformed.
Operating Instructions/Maintenance
• Adjust the brackets on the header transport to best t your make and model header.
Note: When mounting the header, NEVER position yourself under or near the header. Securely fasten the header to the
header transport.
• Do not exceed the load and size limits of the unit.
• Keep the tires properly inated. Both under ination and over ination can greatly reduce tire life. Inate 235-85 R16 tires to 80 psi.
• Inspect bracing and welds periodically and repair immediately, if needed. Failure to repair could cause extensive damage and
greatly reduce the life of the unit.
• Repack the bearings in the hub assembly once a year or as needed. Use a good quality LS EP2 severe duty, high shock load, lithium-
based grease.
• Check the wheel nuts often and keep them properly tightened.
WARNING: Check safety chains for broken, stretched or damaged link or end ttings. Replace chains if found to be
damaged. Do not weld safety chains.
Braking System Requirements
• Stopping distance increases with speed and weight of towed loads and on slopes. Towed loads with or without brakes that are too
heavy for the tractor or are towed too fast can cause loss of control. Consider the total weight of the equipment and its load.
Note: Observe these recommended maximum road speeds, or local speed limits which may be lower.
• If towed equipment does not have brakes, do not travel more than 20 mph (32 km/h) and do not tow loads more than 1.5 times the
tractor weight.
• If towed equipment does have brakes, do not travel more than 25 mph (40 km/h) and do not tow loads more than 4.5 times the trac-
tor weight.
• Ensure the load does not exceed the recommended weight ratio. Use additional caution when towing loads under adverse surface
conditions, when turning, and on inclines.
DANGER: Tow loads safely.

Operations/Maintenance
Adjusting Push-Pull Rod to Align Front and Rear Axles
Before initial operation of header transport, follow these steps to align front and rear wheels while under load:
1. With the transport empty, loosen both nuts on the push-pull rod. The push-pull rod is left hand threaded on one end and right hand
threaded on the other end to adjust alignment like a turnbuckle. One of the nuts is pictured in blue in the diagram below.
2. Place combine header on transport.
3. Drive the loaded transport in a straight line on level ground to check alignment.
4. Adjust push-pull rod by rotating the main rod body.
5. Repeat steps 3 and 4 until the transport rear wheels are aligned with front wheels.
6. Remove combine header from transport.
7. With the transport empty, tighten both nuts on the push-pull rod.
8. Return the combine header to the transport.
9. With the nuts on the push-pull rod tightened, drive loaded transport in a straight line on level ground to conrm alignment.

DANGER: BE CERTAIN THAT ALL POWER IS SHUT OFF BEFORE SERVICING THE 4 WHEEL STEER HEADER TRANSPORT.
Hub Removal:
• Elevate and support the trailer unit carefully.
• Remove the wheel.
• Remove the grease cap by carefully prying pregressively around the ange ofthe cap.
• Remove the cotter pin from the spindle nut or, in the case of E-Z Lube versions, bend the locking tang to the free position. For E-Z
Lube axles produced after February 2002, a new type of retainer is used. Gently pry o retainer from the nut and set aside.
• Unscrew the spindle nut (counterclockwise) and remove the spindle washer.
• Remove the hub from the spindle, being careful not to allow the outer bearing cone to fall out. The inner bearing cone will be re-
tained by the seal.
• For 7,200 lb. and 8,000 lb. axles, a hub puller should be used to assist in drum removal.
Bearing Lubriation:
Along with bearing adjustment, proper lubricatino is essential to the proper function and reliability of your trailer axle. Bearings should
be lubricated every 12 months or 12,000 miles. The method to repack bearing cones is as follows:
• Place a quantity of grease into the palm of your hand.
• Press a section of the widest end of the bearing into the outer edge of the grease pile closest to the thumb forcing grease into the
interior of the bearing.
• Repeat this while rotating the bearing from roller to roller.
• Continue this process until you have the entire bearing completely lled with grease.
• Before reinstalling, apply a light coat of grease on the bearing cup.
Use a good quality LS EP2 severe duty, high shock load, lithium-based grease.
Bearing Adjustment and Hub Replacement:
If the hub has been removed or bearing adjustmennt is required, the following adjustmnet precedure must be followed:
• After placing the hub, bearings, washers, and spindle nut back on the axle spindle in reverse order as detailed in the previous
section on hub removal, rotate the hub assembly slowly while tightening the sprindle nut to approximately 50 ft-lbs (12”wrench or
pliers with full hand force).
• Then loosen the spindle nut to remove the torque. Do NOT retate the hub.
• Fingle tighten the spindle nut until just snug.
• Back the spindle nut out slightly until the rst castellatin lines up with the cotter key hole and insert the cotter pin (or looking toang
in the case of E-Z Lube).
• Bend over the cotter pin legs to secure the nut (or locking tang in the case of E-Z Lube).
• Nut should be free to move with only restaint being the cotter pin (or locking tang).
For axles using the new nut retainer:
• Finger tighten the nut until just snug, align the retainer to the machined at on the spindle and press the retainer onto the nut. The
retainer should snap into place. Once in place the retainer/nut assembly should be free to move slightly.
• If the nut is too tight, remove the retainer and back the nut o spproximately one twelfth of a turn and reinstall the retainer. The nut
should now be free to move slightly.
• Reinstall grease cap.
E-Z Lube Lubrication:
• Remove the rubber plug from the end of the grease cap.
• Place a standard grease gun onto the grease tting located in the end of the spindle. Make sure the grease gun nozzle is fully
engaged on the tting.
• Pump grease into the tting. The old displaced grease will begin to ow back out the cap around the grease gun nozzle.
• When the new clean grease is observed, remove the grease gun, wipre o any excess, and replace the rubber plug in the cap.
• Rotate hub or drum while adding grease.
