GENERAL SPECIFICATIONS LOAD RITE is a registered member of the National Marine Manufacturers Association (NMMA) and the North American Trailer Manufacturers (NATM) association. All LOAD RITE trailers are designed and built to meet all US DOT specifications and NMMA certification. I. CAPACITY Imprinted on your trailer certification plate (VIN sticker located on the front left side of your trailer) is the GVWR capacity.
Blue – disc brake free-backing solenoid, to be wired into tow vehicle back up lights The above wires each correspond with individual circuits on the tow vehicle. Refer to your dealer, hitch installer, or local automotive repair shop to have the proper vehicle connector installed. To avoid trouble with the trailer lighting system, LOAD RITE recommends the following: A. Make certain the tow vehicle is equipped with a proper harness connection to avoid overloading circuits. B.
Section F) and the bearing retainer or cotter pin. Always replace the retainer or cotter pin. DO NOT REUSE! Tighten the spindle nut a little more than "finger tight" (approximately 2024 inch pounds). When the nut is tensioned properly the wheel should rotate easily and have no end play. Reassemble in reverse of disassembling using a new retainer or cotter pin. NOTE: Bearing adjustment should be checked after the first 75 miles of service and every year after. F.
with cold galvanizing spray paint. This product can be obtained through any LOAD RITE dealer, or most paint, hardware, or marine stores. Always thoroughly dry all components, especially brakes, before storage. TRAILER ADJUSTMENTS (Adjustable units only) Most LOAD RITE trailers are designed to be fully adjustable. Available models are designed to adjust to most any variation in width, hull and bow design.
DETERMINING TONGUE WEIGHT (TW) NOTE. Gross trailer weight (GTW) is the actual weight of the trailer fully loaded (including trailer, boat, motor, fuel and accessories). Tongue weight (TW ) is the downward force exerted on the hitch ball at the trailer coupler. In most cases, this should be 5 to 7 percent of GTW (refer to previous Trailer Adjustment section). Tongue weight should be directly measured with a tongue weight scale (shown). If unavailable, tongue weights of up to 200 Ibs.
the rollers are fixed with no adjustment). NOTE: It is important to remember that boats with longitudinal strakes or chines should have the rollers adjusted to run on the flat area of the hull between the strakes or chines. Also note that the rollers should be lubricated at least once a year, preferably at the start of the season, and possibly a second or third time depending on the amount of usage and water immersion. Use a dry graphite lubricant to lube the roller hub.
OPERATING INFORMATION AND PRE-TRIP CHECKLIST Always tie the boat securely at the bow and stern. Do not rely solely on the winch cable/strap to secure your boat. I. TOWING VEHICLE INFORMATION Check with your marine dealer to determine the proper towing vehicle capacity for the size load to be trailered. Most vehicles require a trailer towing package. Refer to your vehicle manufacturer to determine if your tow vehicle is properly equipped for your intended use.
BRAKE TROUBLESHOOTING A. Excessive travel in actuator mechanism: Possible cause: Corrective action: Low fluid in master cylinder reservoir; air in hydraulic lines. Refill master cylinder and bleed system. Leaking primary cup in master cylinder; ports closed or restricted with dirt; defective hoses; leaking check valve fails to hold hydraulic pressure. Check all components and make corrections required. Excessive lining-to-drum clearance. Adjust brakes (drum) or replace linings.
PROPERLY ATTACHING YOUR TRAILER TO THE TOW VEHICLE Mechanical attachment of your trailer to the tow vehicle Depending upon capacity, your trailer is equipped with a coupler that accepts either a 2” or 2-5/16" diameter tow ball with a centerline 18” to 21” from the ground. The coupler is clearly marked for this requirement. Make certain your tow vehicle is properly equipped and set up. Once attached, trailer frame should be parallel to level ground.
Once you are certain that your tow vehicle is equipped with a properly sized, rated, and positioned ball, raise the trailer on the tongue jack so that the ball of the tow vehicle can be maneuvered directly beneath the ball socket of the actuator. Remove any safety lock pins from the actuator lever and move the lever to the forward position. Crank the handle of the tongue jack and lower the actuator socket over the tow vehicle ball.
Attaching the trailer electrical system to the tow vehicle Your trailer is equipped with a six-wire, five-connector wiring harness. function as follows: White – ground The colors Brown (2) – taillights, sidemarker lights, and clearance lights for each side of the trailer Yellow – left turn and stop light Green – right turn and stop light Blue – disc brake free-backing solenoid, to be wired into tow vehicle back up lights The above wires each correspond with individual circuits on the tow vehicle.
OPERATING YOUR TRAILER EQUIPPED WITH DISC BRAKES CHECK FLUID LEVEL The disc brakes on your trailer function under the surge principle. As the tow vehicle brakes are applied, the trailer pushes, or “surges”, against the tow ball. This action generates pressure in the trailer hydraulic system and causes the brake calipers to squeeze the brake pads and grip the rotors. Fill Cap Solenoid Wire Remove the fill cap and check the brake fluid level at each use. Always top off with DOT 3 brake fluid as needed.
WARNING - LOAD RITE RECOMMENDS THAT ALL MAINTENANCE BE PERFORMED BY A QUALIFIED MECHANIC. MAINTAINING YOUR TRAILER EQUIPPED WITH DISC BRAKES The disc brakes on your trailer have been engineered for the rigorous duty of a marine environment. Like any mechanical system, the disc brakes on your trailer require periodic inspection and preventive maintenance. LOAD RITE recommends brake system service be performed annually for optimum, reliable system performance.
WARNING - LOAD RITE RECOMMENDS THAT ALL MAINTENANCE BE PERFORMED BY A QUALIFIED MECHANIC. IMPORTANT SAFETY NOTE Never raise a trailer wheel off the ground for service unless the trailer is safely attached to the tow vehicle, and one wheel on each side of the trailer is fully chocked. DISC BRAKE MAINTENANCE PROCEDURE Work on only one wheel at a time. Inner Pad Thickness Begin by removing the wheel and visually Mounting inspecting brake pad thickness.
Carefully remove the rotor (or hub) from the spindle taking care to prevent the outer bearing from falling out of the hub assembly. Remove the outer bearing and set aside. Invert the hub assembly so the inner seal is visible. Remove the inner seal and discard. Replace with a new seal at reassembly. Remove the inner bearing and set aside. SERVICE NOTE Always replace these items at each hub service! Retainer design may vary by model. Outer Retainer Wipe each bearing with a clean cloth.
TIRE SAFETY INFORMATION 1.1. Tire Safety Information This portion of the User’s Manual contains tire safety information as required by 49 CFR 575.6. Section 2.1 contains “Steps for Determining Correct Load Limit - Trailer”. Section 2.2 contains “Steps for Determining Correct Load Limit – Tow Vehicle”. Section 2.3 contains a Glossary of Tire Terminology, including “cold inflation pressure”, “maximum inflation pressure”, “recommended inflation pressure”, and other nontechnical terms. Section 2.
number. In any case, remember: the total weight of a fully loaded trailer can not exceed the stated GVWR. For trailers with living quarters installed, the weight of water and propane also need to be considered. The weight of fully filled propane containers is considered part of the weight of the trailer before it is loaded with cargo, and is not considered part of the disposable cargo load. Water however, is a disposable cargo weight and is treated as such.
Subtract the empty weight of your trailer from the GVWR stated on the VIN label. That weight is the maximum available cargo capacity of the trailer and may not be safely exceeded. 1.3. Steps for Determining Correct Load Limit – Tow Vehicle 1. Locate the statement, “The combined weight of occupants and cargo should never exceed XXX lbs.,” on your vehicle’s placard. 2. Determine the combined weight of the driver and passengers who will be riding in your vehicle. 3.
a manner that encloses the rim flanges inside the air cavity of the tire. Curb weight The weight of a motor vehicle with standard equipment including the maximum capacity of fuel, oil, and coolant, and, if so equipped, air conditioning and additional weight optional engine. Extra load tire A tire designed to operate at higher loads and at higher inflation pressures than the corresponding standard tire. Groove The space between two adjacent tread ribs.
The rim on which a tire is fitted for physical dimension requirements. Pin Weight The downward force applied to the 5th wheel or gooseneck ball, by the trailer kingpin or gooseneck coupler. Non-pneumatic rim A mechanical device which, when a non-pneumatic tire assembly incorporates a wheel, supports the tire, and attaches, either integrally or separably, to the wheel center member and upon which the tire is attached.
weight or accessory weight, including heavy duty brakes, ride levelers, roof rack, heavy duty battery, and special trim. Radial ply tire A pneumatic tire in which the ply cords that extend to the beads are laid at substantially 90 degrees to the centerline of the tread. Recommended inflation pressure This is the inflation pressure provided by the vehicle manufacturer on the Tire Information label and on the Certification / VIN tag.
of wear of the tread. Vehicle capacity weight The rated cargo and luggage load plus 68 kilograms (150 lbs.) times the vehicle’s designated seating capacity. Vehicle maximum load on the tire The load on an individual tire that is determined by distributing to each axle its share of the maximum loaded vehicle weight and dividing by two.
Recognize that the time you spend is minimal compared with the inconvenience and safety consequences of a flat tire or other tire failure. 1.6. Safety First–Basic Tire Maintenance Properly maintained tires improve the steering, stopping, traction, and load-carrying capability of your vehicle. Underinflated tires and overloaded vehicles are a major cause of tire failure.
1.6.4. Steps for Maintaining Proper Tire Pressure Step 1: Locate the recommended tire pressure on the vehicle's tire information placard, certification label, or in the owner's manual. Step 2: Record the tire pressure of all tires. Step 3: If the tire pressure is too high in any of the tires, slowly release air by gently pressing on the tire valve stem with the edge of your tire gauge until you get to the correct pressure.
1.6.9.1. Information on Passenger Vehicle Tires Please refer to the diagram below. P The "P" indicates the tire is for passenger vehicles. (Trailer tires will carry the "ST" indication, for Special Trailer service.) Next number This three-digit number gives the width in millimeters of the tire from sidewall edge to sidewall edge. In general, the larger the number, the wider the tire. Next number This two-digit number, known as the aspect ratio, gives the tire's ratio of height to width.
Letter Rating Speed Rating Q 99 mph R 106 mph S 112 mph T 118 mph U 124 mph H 130 mph V 149 mph W 168* mph Y 186* mph Speed Rating The speed rating denotes the speed at which a tire is designed to be driven for extended periods of time. The ratings range from 99 miles per hour (mph) to 186 mph. These ratings are listed below. Note: You may not find this information on all tires because it is not required by law.
1.6.9.2. UTQGS Information Treadwear Number This number indicates the tire's wear rate. The higher the treadwear number is, the longer it should take for the tread to wear down. For example, a tire graded 400 should last twice as long as a tire graded 200. Traction Letter This letter indicates a tire's ability to stop on wet pavement. A higher graded tire should allow you to stop your car on wet roads in a shorter distance than a tire with a lower grade.
Load Range This information identifies the tire's load-carrying capabilities and its inflation limits. 1.7. Tire Safety Tips Preventing Tire Damage Slow down if you have to go over a pothole or other object in the road. Do not run over curbs or other foreign objects in the roadway, and try not to strike the curb when parking. Tire Safety Checklist Check tire pressure regularly (at least once a month), including the spare.
