MPG460XT Group 1: Frame Components Bag 11491 Bag 11462 Group 2: Axle / Spring Components 2 Bag 11476 technical@maloneautoracks.
MPG460XT Group 3: Lighting Components Group 4: Fender Components Bag 11468 Bag 11464 Group 5: Coupler Components Bag 11494 technical@maloneautoracks.
MPG460XT Group 6: Load Bar Components Bag 11489 FRAME ASSEMBLY (Group 1) 1. We assemble the frame on its back to make it easier to install the springs and axle. Once the springs and axle assembly is installed we will flip the trailer over to complete the assembly. So first, layout the frame components upside down as shown. The spring bracket mounting holes should be facing up. All the decals should all be upside down. 4 technical@maloneautoracks.
MPG460XT 2. Attach the spring hanger brackets to the frame. The U shaped shackle bolt brackets mount to the front and the C shaped “slipper” brackets mount to the rear as shown. Use 3/8” x 1” bolts and nuts. Assemble with the nuts on the inside of the frame rails. Fully tighten all 8 bolts now. 3. Lay the two frame cross members in between the frame rails. The two holes in the middle should face DOWN as shown. Channels face each other. 4.
MPG460XT 5. Install the clip nut as shown on the end of the short piece of 2x3 tubing. Note, the parts are symetrical so it doesn’t matter which way they are turned. Then fit the rear tongue support bracket over the clip nut and install a short bolt and washer. Hand tight only. Now flip the rear tongue support assembly over so the bolt head on the bottom. 6. Slide the rear tongue support assembly, bolt head down, in between the frame rails as shown. 7.
MPG460XT 8. Bolt the tongue support to the frame rails using 3/8” x 1” carriage head bolts. Note the square heads go on the outside with the square holes in the frame. Assemble with washers and nuts on the inside. Don’t fully tighten. 9. Install the 1/2” x 3-1/4” bolts with washers on both sides thru the retractable tongue box. Don’t fully tighten. 10.
MPG460XT SPRING AND AXLE ASSEMBLY (Group 2) 1. Set the envelope containing the manufacturer’s certificate of origin (MCO) and VIN labels aside in a safe place. 2. Spin the axle to find the side with the spring centering holes. These holes mate with the spring center stud (shown to the left) 8 technical@maloneautoracks.
MPG460XT 4. Run each nut down but, ONLY UNTIL THE NUTS ALMOST TOUCH THE PLATE !! You will need lots of wiggle in the springs to fit them into the spring brackets in the next step. 5. Lift the axle/spring assembly to the trailer frame and slide the slipper spring ends into the slipper spring brackets as shown. Then lower the axle resting the spring eyes on the front brackets however they land. technical@maloneautoracks.
MPG460XT 6. Wiggle the spring eyes into the front hanger brackets and bolt using 1/2” x 3” bolts and self locking nuts. Nuts to the inside. Tighten the shackle bolts ONLY until they grip the sides of the brackets. Remember, this is a hinge. The bolt should remain still in the bracket allowing the spring eye to move freely. 7. Now that the axle assembly is attached to the frame, tighten the axle plate U-bolts evenly until there is a slight bend in the tie plates. Don’t over tighten. 8.
MPG460XT 10. Tighten the lug firmly to 75 to 85 foot pounds of torque. 11. Slip the large U-bolt in place over the retractable tongue assembly as shown. Install the 2 hole frame strap under the assembly and install the 1/2” nuts. Turn the U-bolt at an angle as shown so its legs are against the tubes. Fully tighten the 2 nuts. Now tighten the bolt in the center of the rear tongue support. 12. Install the 2” x 3” plastic hole plug into the end of the frame as shown. Use your hammer to tap it in.
MPG460XT 13. Attach the rubber stand-up feet to the rear of the frame as shown. 14. Attach the retractable tongue retainer bracket to the inside of the rear frame crossmember as shown. 15. Install the wiring harness extension thru the tongue. The easiest way is to let gravity pull the harness through. Make a fold in the harness near the end with the white ground wire. Push the fold into a heavy socket (or tape any heavy object to the fold).
LIGHT ASSEMBLY (Group 3) MPG460XT REFERENCE: Trailer Wiring Color Code •Brown = running lights •Yellow = left turn / left brake •Green = right turn / right brake •White = ground 1. Attach the tail lamp brackets to the frame as shown using 3/8” x 1” carriage head bolts and nuts. No washers are needed. 2. Sandwich the license plate mounting bracket between the left side lamp and the left side tail lamp bracket. Attach the tail light using the nuts provided with the lamp kit.
MPG460XT 4. Routing the wiring harness. - Route the GREEN/BROWN wire along the RIGHT side of the frame. - Route the YELLOW/BROWN wire along the LEFT side of the frame. 5. Use the clips provided to secure the wire to the inside of the frame channel as shown. 6. Position the harness connector off center close to a frame rail as shown. This holds the connector up at the frame during trailering. 7. The white wire on the connector is not needed at this location on the trailer.
MPG460XT 8. Route the wires thru the mid cross member as shown then secure the harness in place using the frame clips provided. 9. Connecting the side lamps. To control cutting between two conductors without damaging the wire or yourself, press the wire flat against the frame then squarely push the blade tip between the conductors until it hits the frame. Then with the knife tip still held firmly against the frame, pull the wire gently away from the frame so the blade cuts between the wires.
MPG460XT 12. Route the wires to the rear along the frame. - Exit the frame via the slotted hole under the lamp bracket. - Use wire clips to secure the wires. Bring the wires to the tail lamps, add 10 inches more to serve as extra length for service work, and cut there. Coil the extra. 13. Strip 1/2” of insulation off the ends of all 4 tail light wires. - Slightly twist the exposed copper strands to stiffen them.
FENDER ASSEMBLY (Group 4) MPG460XT 1. Connect all 4 fender brackets to the fenders using 3/8” x 3/4” slot head screws and nuts. Assemble with the nuts to the inside of the fenders as shown. No washers here. Fully tighten all 8 screws and nuts. Note: fenders are symmetrical and fit on either side of the trailer. technical@maloneautoracks.
MPG460XT Note that when bolting the mounting brackets to the frame you will install a washer on both sides, under the head of each bolt and under each nut. 2. Using 3/8” x 1” bolts, washers on both sides, and nuts, attach the fender brackets to the slotted holes in the frame as shown. NOTE you will use the center hole in the bracket and the outside two slotted holes in the frame. 3. Tighten bolts fully and repeat for other side. 18 technical@maloneautoracks.
COUPLER ASSEMBLY (Group 5) MPG460XT 1. Installing the ground wire connector. Strip 3/8” of insulation off the white ground wire and crimp on the ring connector as shown. 2. Assemble the tongue skid and safety chain assembly with a 3/8” x 1-1/2” bolt as shown. Use washers above and below the chain ends. technical@maloneautoracks.
MPG460XT 3. Place the skid and chain assembly under the tongue and insert the bolt up through the skid bolt hole on the bottom of the tongue as shown. 4. Slip the ring terminal over the bolt and install the nylon lock nut hand tight. 5. Check that the rear end of the skid is still in its hole in the bottom of the tongue. Tighten the bolt while holding the nut stationary. This way the ring terminal remains straight. 6. Install the coupler and coupler handle onto the tongue as shown.
LOAD BAR ASSEMBLY (Group 6) MPG460XT 1. Attach a load bar support tube onto the rear cross member. Cross the U-Bolts. Center the support tube and brackets on the trailer and tighten. 2. Attach the second support tube 48 inches forward. Install these U-bolts parallel, not crossed. Measure 48” on both sides of the trailer to be sure the load bar is on straight, then tighten the U-bolts. technical@maloneautoracks.
MPG460XT 3. Use your hammer and carefully pound the end plugs into the ends of the support tubes. 4. Slip the load bar brackets over the load bars (as shown) and loosely install the two small carriage bolts / nuts through each bracket trapping the load bars inside the brackets. 5. Install and hand tighten the bolts holding each bracket to the support tube. 22 technical@maloneautoracks.
MPG460XT 6. Center the load bars to the trailer, then tighten all 12 bracket bolts. 7. Go back now and re-check that all nuts and bolts on the entire trailer are securely tightened. DECALS, REGISTRATION & TITLING Apply the TIRE AND LOADING Decal and the VIN Decal as shown to the right, onto the left side of the frame. - Be sure to clean the frame before applying the decals.
MPG460XT To use the retractable tongue. 1- Disconnect the extension harness from the frame harness and tuck the harness into the rear of the tongue. 2- Remove the hitch pin from the frame. 3- Slide the tongue into the frame until the end of the tongue aligns with the retainer bracket as shown to the right. 4- Install the hitch pin and retainer ring as shown. When retracted, the trailer may be stood up on end against a wall, tree or post for reduced footprint storage as shown.
