2000 – 2006 TOYOTA TUNDRA SPORT DUTY UNDERCARRIAGE MOUNTING INSTRUCTIONS The mounting procedure outlined below covers the 2000 – 2006 Toyota Tundra trucks. You will need to refer to the illustrations and familiarize yourself with each of the undercarriage components and their relative position to each other. Then proceed as follows: 1. Begin by removing the bolts holding the skid plate to the bottom of the bumper and the rear cross member. Remove the skid plate. Some vehicles are equipped with an additional skid plate that wraps up in front of the bumper. This skid plate must be removed also. 2. Remove the bolts connecting the tow hook, tie down brackets, and skid plate brackets (Refer to Figure 1) to the bottom of the frame. The bolts and tow hook will be used in the undercarriage installation. 3. Assemble Driver Side Push Beam Support Plate (62B) to the bottom of the driver side frame rail. Begin by installing the bolts removed in Step 2 into the two holes in the bottom of Diver Side Push Beam Support Plate (62B) . Tighten these two bolts. Next, drill the inside and outside frame wall for the upper hole in Driver Side Push Beam Support Plate (62B). Install one ½”-13 X 4-1/2″ Hex Head Bolt (D) and one ½”-13 Lock Nut (B) in the drilled hole. Tighten this bolt. 4. Repeat Step 3 on the passenger side frame rail. Include the tow hook over Passenger Side Push Beam Support Plate (62A). The skid plates, tie down brackets, and skid plate brackets (See Figure 1) will no longer be used but should be retained in case the undercarriage is ever removed. 5. Install Push Beam Assembly (62) between Push Beam Support Plates (62A & 62B) using eight ½”-13 X 1-1/2″ Hex Head Bolts (A) and eight ½”-13 Lock Nuts (B). For Light Duty Plow applications, the center of the receiver hole in Push Beam Assembly (62) should be 14-1/2″ from the ground. Leave hardware finger tight. 6. Assemble Angle Bracket (75) to the back of Push Beam Assembly (62) using four ½”-13 X1- 1/2″ Hex Head Bolts (A) and four ½”-13 Lock Nuts (B). Leave hardware finger tight. 3 7. Assemble the rear portion of Angle Bracket (75) to the truck’s cross member using two Nut Plates (101), two ½” Split Lock Washers (C) and two ½”-13 X 1-1/2″ Hex Head Bolts (A) . Nut Plates (101) must be inserted into the cross member through the large hole in the rear of the cross member. 8. Tighten all hardware beginning at the rear of Angle Bracket (75) and working forward. 9. With all undercarriage parts in place, securely fasten all mounting hardware. It is important that all fasteners be properly torqued (see Fig. 3) to assure a safe operating plow. Re-tighten all fasteners after 2 hours of plowing.
