4 Introduction Congratulations on the purchase of your New Norbert Trailer. You have just bought one of the most durable trailers on the road today. Whether it s for work or pleasure, your trailer will give you years of trouble free use with proper care and maintenance. Norbert s Manufacturing Ltd. has been in operation since A farmer named Norbert Vanwynsberghe founded the company in the mid 80 s. Norbert started welding in his small shop as a secondary income to farming. Norbert soon found himself very busy and felt he could build a better trailer than what was available on the market. Norbert being a cattle man himself, designed a unibody stock trailer that would suit his needs as well as others. A strong, easy cleaning, rattle free trailer was built and the company has been growing since. In January 1996 Norbert was taken from us in a tragic snowmobile accident. Taking on the family run business are Norbert s two children. Norbert s Manufacturing currently employs 45 local people with approximately trailers being sold North American wide per year. Norbert s Manufacturing uses the finest products available and each trailer is checked before it leaves the facility to ensure quality control. Norbert s is always striving to build a better trailer and to stay on top as an industry leader. For all your trailer needs Make It Norbert s 2

5 Knowing Your Trailer Stock Trailer 1) Your stock trailer has a high grade automotive finish on the outside and epoxy coating on the inside. Just like your vehicle it must be washed and maintained to keep it looking new. Wash trailer frequently with soap and water to rid trailer of salt and other debris. If pressure washer is to be used, hold it away from paint. Try not to use direct pressure as some washers have a tremendous amount of PSI which is hard on paint finishes. Waxing the exterior will help in the prevention of oxidation and keep your trailer looking like new. Try and clean the inside of your trailer as often as possible. Use a plastic shovel rather than steel, as plastic will not scrape the paint off the sides. If mats are used, try and pull them out frequently to avoid manure build up against walls. 2) Your trailer is equipped with grease fittings on side and rear doors. Grease regularly to avoid hinges from seizing. This should be done at least a couple of times a year. The rear door has two spring pin closures on the left and a spring lever on the lower middle. The three levers will help hold the door closed in three points to avoid bending. The center closure will prevent slide door from opening and is lockable. The left lower closure has a safety feature in that if livestock were to kick the rear door the catch on the closure will stop the door from hitting you. The slider door can also be opened from the inside of the trailer by pushing down on the lever in the right corner. 3

6 3) There is an oiling hole located on the top of the jack handle shaft. A couple drops of oil will help ease shaft movement. 4) The neck is adjustable and should be checked frequently to ensure it is tight. There is an adjuster bolt on the rear of the neck to snug the tube tight so as not to move. 5) The center gate has a locking lever on the outside of the trailer. When moved to the left placing it under the locking tab the gate cannot be opened from the inside of the trailer. When moved to the right the lever can be pulled from the outside to release the gate. This eliminates the need to go in the trailer. 6) Your wheels must be checked and re torque after first 10 miles, 25 miles and at 50 miles. Check periodically thereafter. See (Torque chart p.19) 7) Every trailer equipped with electric brakes will have a Breakaway System installed. The battery is mounted inside the neck and the breakaway switch is located beside the coupler. The breakaway switch is a safety feature designed to power the magnets and apply braking force in the event the trailer becomes disconnected. In order for this to happen the battery must be charged and maintained. See (Breakaway System p.20) 8) Brakes and bearing preload should be adjusted after the first 200 miles. See (Brake adjustment p.13) It is good practice to inspect and clean your trailer brakes at yearly intervals or more often as use and performance requires. 4

7 9) All Norbert trailers are equipped with greaseable hubs on 7000 lb. axles and under. You must maintain grease in the axle by pumping grease into the zerk located on the outside of the hub by way of a grease gun. There is a relief hole on the backside of the spindle so you cannot overfill. Axles larger than 7000 lb. are filled with oil. Levels can be checked by viewing through the glass caps on the outside of the hub. Oil must be level with the filling site on the glass. If oil is to be added it can be filled by removing the black rubber plug on the outside of the glass cap or the one located on the side of the hub. See (p.12) For proper wheel bearing lubrication. It is a good idea to check condition of bearings once a year to see if they need repacking, fresh oil or replacement. 5

8 Flat Deck Trailer 1) Your flat deck trailer has an industrial finish on the exterior. Just like your vehicle it must be washed and maintained to keep it looking like new. Wash trailer frequently with soap and water to rid trailer of salt and other debris. If pressure washer is to be used, hold it away from paint. Try not to use direct pressure as some washers have a tremendous amount of PSI which is hard on paint finishes. Waxing the exterior will help in the prevention of oxidation and keep your trailer looking like new. 2) Flat decks equipped with beavertails have four grease fittings. Two are located on the bottom side of the center drop at the hinge. The other two are located at the hinge of the fold down gate that holds up the center drop. Grease regularly to avoid hinges from seizing. The beavertail ramps are spring loaded to assist in the lifting of the ramps. There is an over center latch located on the underside of each ramp. These latches hold the ramps down to avoid being flipped over and dragged down the highway. Both ramps are adjustable inwards so smaller equipment can be loaded. 3) There is an oiling hole located on the top of the jack handle shaft. A couple drops of oil will help ease shaft movement. 4) The neck is adjustable and should be checked frequently to ensure it is tight. There is an adjuster bolt on the rear of the neck to snug the tube tight so as not to move. 5) Your wheels must be checked and re torqued after the 6

9 first 10 miles, 25 miles and at 50 miles. Check periodically thereafter. (Torque chart p.19) 6) Every trailer equipped with electric brakes will have a Breakaway System installed. The battery is mounted underneath the neck and the breakaway switch is located beside the coupler. The breakaway switch is a safety feature designed to power the magnets and apply force in the event the trailer becomes disconnected. In order for this to happen the battery must be charged and maintained. See (Breakaway System p.20) 7) Brakes and bearing preload should be adjusted after the first 200 miles. See (Brake adjustment p.13) It is good practice to inspect and clean your trailer brakes at yearly intervals or more often as use and performance requires. 8) Norbert trailers are equipped with greaseable axles on all axles up to 7000 lb. These axles are equipped with a grease zerk. You must maintain grease in the axle by pumping grease into the zerk by way of a grease gun. There is a grease hole on the backside of the spindle so you cannot overfill. Axles larger than 7000 lb. are filled with oil. Levels can be checked by viewing through the glass caps on the outside of the hub. Oil must be level with the filling site on the glass. If oil is to be added it can be filled by removing the black rubber plug on the outside of the glass cap or the one located on the hub. See (p.12) For proper wheel bearing lubrication. It is a good idea to check condition of bearings once a year to see if they need repacking, fresh oil or replacement. 7

10 Recommended Usage of Sure-Lube System Usage of the Sure-Lube system will not eliminate the need for general maintenance and inspection of the hub/drum components. However, will aid in the savings of time and effort. Recommended maintenance of this system is to insert Lithium base wheel bearing grease through the Zerk fitting provided in the end of the dust cap until it flows freely from the vent hole located in the rear of the spindle. The above procedure should be followed at regularly scheduled intervals; such as oil changes or chassis lubrications with usage and climactic conditions in mind. It is strongly urged that bearing components be inspected every 12,000 miles or annually to insure that no abnormal wear or bearing setting has resulted. 8

11 The Power of Protection When it comes to protection, nothing beats the patented power of Sure Lube. There s no springs. Or rubber plugs. Or O-rings. Sure Lube uses a revolutionary double lip springloaded seal that ensures outer/inner bearing protection from corrosion, wear and water entry. It s a time-saver, too. Sure Lube lets you grease or re-pack bearings with just a grease gun without disassembly. Sure Lube. When only the best will do. 9

15 GENERAL MAINTENANCE BRAKE ADJUSTMENT On trailers equipped with 8,000 15,000 lb. axles brakes are self adjusting. Brakes should be adjusted after the first 200 miles of operation when the brake shoes and drums have seated, and at 3000-mile intervals or as use requires. The brakes should be adjusted in the following matter. 1. Jack up trailer and secure on adequate capacity jack stands. Support trailer on rear bumper or trailer frame located just behind the rear axle. Never lift or support trailer on axles. Check that the wheel and drum rotate freely. 2. Remove the adjusting hole cover from the adjusting slot on the bottom of the brake backing plate. 3. With a screwdriver or standard adjusting tool, rotate the starwheel of the adjuster assembly to expand the brake shoes. Adjust the brake shoes out until the pressure of the linings against the drum makes the wheel very difficult to turn. 4. Then rotate the starwheel in the opposite direction until the wheel turns freely with a slight lining drag. 5. Replace the adjusting hole cover and lower the wheel to the ground 6. Repeat the above procedure on all brakes. 13

16 Brake Cleaning and Inspection Your trailer brakes must be inspected and serviced at yearly intervals or more often as use and performance requires. Magnets and shoes must be changed when they become worn or scored thereby preventing adequate vehicle braking. Clean the backing plate, magnet arm, magnet, and brake shoes. Make certain that all the parts removed or replaced in the same brake and drum assembly. Inspect the magnet arm for any loose or worn parts. Check shoe return springs, and adjuster springs for stretch or deformation and replace if required. Brake Lubrication Before reassembly, apply a light film of Lubriplate, anti-seize compound, or similar product on the brake anchor pin, adjuster threads, the actuating arm bushing and pin and the areas on the backing plate that are in contact with the brake shoes and magnet lever arm. Apply a light film of grease on the actuating block mounted on the actuating arm. Magnets Your electric brakes are equipped with high quality electromagnets that are designed to provide the proper input force and friction characteristics. Your magnets should be inspected and replaced if worn unevenly or abnormally. As indicated below a straightedge should be used to check wear. 14

17 Even if wear is normal as indicated by your straightedge, the magnets should be replaced if any part of the magnet coil has become visible through the friction material facing of the magnet. It is also recommended that the drum armature surface be refaced when replacing magnets. Magnets should also be replaced in pairs both sides of an axle. Shoes and Linings A simple visual inspection of your brake linings will tell if they are usable. Replacement is necessary if the lining is worn (to within 1/16 or less), contaminated with grease or oil, or abnormally scored or gouged. Hairline heat cracks are normal in bonded linings and should not be a cause for concern. It is important to replace both shoes on each brake and both brakes of the same axle. This is necessary to retain the balance of your brakes A properly installed vacuum / hydraulic, air / hydraulic or electric hydraulic system should not require any special attention with the exception of routine maintenance such as shoe and lining replacement. If problems occur, the entire tow vehicle/ trailer braking system should be traced by a qualified 15

18 mechanic using a methodical approach to determine the exact source of the problem. Typical problems in a hydraulic braking system are: Air or Vacuum leaks Hydraulic system leaks Air in brake lines Water or other impurities in brake fluid Rusted or corroded master or wheel cylinders Most of the brake components are very similar to those used in electric brakes, and maintenance is comparable for the hub and drum, shoes and linings, and bearings. 16

21 Torque Requirements Wheel nuts must be re torqued after the first 10 miles, 25 miles, and again at 50 miles. Check periodically thereafter. Wheel Torque Requirements 1/2 studs 95 ft. lbs. 9/16 studs 110 ft. lbs. 5/8 studs 200 ft. lbs. M ft. lbs. Torque Tightening Sequence 19

22 Breakaway System Your trailer is equipped with a breakaway switch. The switch is designed to operated only when the towed trailer separates from the towing vehicle. When this happens the lanyard cable pin is pulled out of the breakaway switch and the switch will close the circuit from the trailer battery to the brakes and put the brakes on. For the breakaway switch to operate properly it is important that the terminal connections are clean, the battery is fully charged and the switch is installed according to the following installation instructions. 1) There should be no obstacles or strain on the lanyard cable to the tow vehicle. The tow vehicle must be able to make sharp left and right turns without strain on the lanyard cable. 2) The lanyard cable should pull out before safety chains become fully extended. 3) Do not let lanyard cable dray on the ground. Fasten cable to the tow vehicle frame or hitch. Never hook on safety chains or tow ball. 4) Test the breakaway switch on a regular basis and make sure the lanyard cable is not damaged and the battery is fully charged. 5) When testing the switch disconnect trailer cord from tow vehicle. Pull lanyard pin out, this will take approximately 20 lbs. of pull. You should hear brakes engage. To double check, move tow vehicle forward to make sure brakes are locked and operating properly. 20

23 6) When test is complete make sure lanyard pin is fully pushed back in. To maximize the life of the battery the following conditions should be met: 1) Avoid over or undercharge. This is the single worst enemy of lead-acid batteries. 2) Batteries should not be stored in a discharge state or at elevated ambient temperature. 3) Avoid exposing batteries to heat! Service life is shortened considerably at ambients above 30 celsius. 4) Due to the characteristics of this battery, after six to nine months of storage, the battery should be recharged. 5) Charge the battery at the proper rate. Current should be limited to less than 1.2 amps. Charge current above 1.2 amps will result in shortened service life. 6) Provide adequate air circulation when charging battery. Do not charge battery in any other container besides the battery box provided. 7) Do not place battery in close proximity to objects which can produce sparks or flames. 8) Do not expose battery case to organic solvents or adhesives. 9) Do not attempt to disassemble batteries. Contact with sulfuric acid may cause harm. 10) Do not throw batteries into fire; batteries so disposed may rupture or explode. 21

27 Trip Preparation Checklist It is extremely critical to follow the steps on this checklist prior to starting a trip with your trailer. By doing so, you are assured that you are taking all the necessary precautions to extend the life of your suspension system. Be sure to allow yourself sufficient time to perform the maintenance required. 1. Check your maintenance schedule to ensure that all maintenance matters are current. Perform any neglected maintenance. 2. Check trailer hitch for signs of wear. Lubricate the hitch if necessary. 3. Make sure that the breakaway battery is charged and inspect safety chains. 4. Inspect the tow vehicle s towing hookup. 5. Load the trailer and adjust the tongue weight so that 8% - 10% of the load is on the tongue. 6. Ensure that you are not over loaded and are staying within the capacity rating of the trailer. 7. Inspect tires for wear and adjust tire pressure according to the tire manufacturer s recommendations. 8 Check wheel nut or bolt torque values. Adjust per the specifications in this manual. 9. Make sure that the brakes are adjusted and synchronized properly. 10. Check all suspension fasteners and retorque if necessary following the procedures outlined in this manual. 11.
