This vehicle was designed and quality inspected to conform with all applicable National Highway T raffic Safety Administration (NHTSA) safety standards. Great Dane Limited Partnership warrants this vehicle to be free from defects in materials and workmanship in accordance with its standard printed warranty (see Appendix).
IN TR ODUC TI O N T his manual has been prepared to assist you in retain- ing the safety , dependability , and performance that are built into Great Dane trailers. It is essential that this trailer receives periodic inspections, maintenance, and service parts replacement.
MA IN TE NA NC E TI PS B REAKING-IN A NEW TRAILER The most critical time in a new trailer ’s life is its initial i n-service check and first month’s “shakedown.” Preventive maintenance mechanics should be alert for under-inflated tires and threaded fasteners that may have loosened from factory-torque settings.
AP PE AR AN CE M AI NT EN AN CE A ppearance maintenance includes cleaning, polishing, corrosion prevention and removal, and protective coating. Y ou must have a working knowledge of each for the complete and proper appearance maintenance of a Great Dane trailer .
EL EC TR IC AL S YS TE M The electrical system on every Great Dane trailer meets or exceeds all federal and state requirements in effect at the time of manufacture. Wherever required by law , lamps and reflectors are marked by the m anufacturer to indicate the appropriate specification with which each complies.
A warning decal, as shown on the previous page, is located on the front of each trail er . Y ou may trace indiv idual e lectri cal cir cuits b y the wire c olors i ndica ted. Refer t o the sch ematic d rawin g and the d ecal for c ondu ctor nu mbers an d wire co lors.
BR A K E CA R E A ND A D J US T M EN T T he trailer brake system will perform safely and efficiently only as long as it is properly maintained and not abused. T railer brakes should be inspected frequently in connection with a T railer Preventive Maintenance (TPM) Program.
O VERSIZE LINERS T o compensate for material removed when refacing brake drums, X (1/16" oversize) and XX (1/8" oversize) liners are furnished by the lining manufacturers. When overs ize lin ers are us ed the dr ums sho uld be mac hined in incr ement s of 1/16" ( radiu s incre ased 1/1 6").
P AR KI NG B RA KE S All axles (except some converter dolly axles) are e quipped with air/spring actuators. Each actuator is separated into two units. The base unit applies the service brakes. The top unit contains a coil spring that must be compressed by air within the chamber to release the parking brakes.
This detailed check takes about two and one-half hours. It’s important to check a representative tractor and trailer each time you order equipment. K eeping an eye on your brake service records will also flag imbalance problems.
INSPECTION I nspect the inner and outer wheel bearing cups, cones and rollers for excessive wear or damage. Refer to bearing and axle manufacturer ’s manuals for inspection and replacement requirements.
SU SP EN SI ON S Check wear pads in hangers. If they are wearing thin, install new pads or the spring will cause permanent damage to the hanger . Do not operate with broken spring leaves. Check to see if all springs can make proper contact with wear pads.
The shock absorbers should be replaced at the first sign of leaking hydraulic fluid. Worn shocks will allow tire hop and yield poor handling characteristics. M any air suspensions are equipped with air control kits. The air control kit allows the raising or lowering of the vehicle bed by inflating or exhausting air from the air suspension.
15 SINGLE-PIECE RIM WHEELS I llustrated, complete safe operating procedures are provided on the wall chart “Mounting and Demounting Procedures for T ruck/Bus T ires” available from the Department of T ransportation, and OSHA.
16 RI M/ WH EE L PR OBL EM S RIM B ASE CRA CKS Circu mfere ntial cr ack at ba ck flan ge radiu s or bead s et. Causes: Overload and/or over inflation, damage due to tire tools, tire bead deep pitting or corrosion. Circumferential cracks in middle of rim.
STUD HOLE CRA CKS H ub or outboard drum may be damaged or broken. Must provide flat backup. Double-capnut wheel mounting preload is force applied to the disc by torquing nuts. Inner cap nut must be tightened before tightening outer nut. This surface should be convex, not concave.
Running a tire under inflated can have serious conse- quences in addition to reducing tread life. Heat buildup can cause the tire body to deteriorate, resulting in sep- aration of the tread from the body or belt ply . A soft tire o verdeflects, causing fatigue breaks in the body cords.
19 TIRE LO ADS G reat Dane T railers, as required by the safety regulations of the National Highway T raffic Safety Administration has assigned a Gross Axle Weight Rating (GA WR) for each axle on the undercarriage. (See example certification plate below .
20 5. Measure the distance, on each side, from the center of the end of the front axle to the center of the end of the rear axle (measurements C and D of the tandem-axles illustration). These measurements m ust be within 1/16" of each other . (Illustrated is a gauge that simplifies this measurement.
21 PI NT LE H OO K 1 . Clean and check for proper operation. This should be done at each TPM. 2. Inspect for worn, damaged or missing parts. Replace only with compatible replacement c omponents. 3. Regularly lubricate the latch and lock pivots with a light-oil lubricant.
SI DE A ND R OOF P ANEL S – V ANS S ide and roof panels are critical structural members of the trailer . Small holes can be patched using an over- lay panel with blind rivets.
d. Check all rollers for smoothness of operations and have all sliding or otherwise damaged rollers replaced. e . Replace frayed, damaged or severely worn pull straps. f. Check the door lock to be sure that it is free, and fully operational. g. Replace broken or damaged hinges.
E xteriors: Cleaning the outside of refrigerated trailers should be done the same way dry-freight vans are cleaned. Live steam does a good job of cleaning and brightening the exterior surfaces of van trailers. Application of a protective transparent coating may b e used to protect the exterior surface from further oxidation.
25 3. Should ignition or combustion of the urethane become evident (flame, smoke, charring, odor , etc.), hot work must be stopped immediately . All flames must be extinguished and additional urethane mate- r ials must be removed from the workpiece and/or workplace before hot work is continued.
R U NN IN G GE AR A SS EM BL Y — PL A TFO RM A ND C UR T AIN SI DE TR AI LE RS MO VEABLE SUSPENSIONS 1 . Always check the condition of the locking holes in the main beam. Holes that are badly worn or elongated will result in undue slack in the slider unit, causing excessive wear and suspension misalignment.
