1973-1993 Dodge W250 and W350 RT3 Undercarriage Mounting Instructions

The mounting procedure outlined below covers 1973 – 1993 Dodge W250 & W350 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. Remove the Front Bumper and Front Bumper Mounting Brackets from the Frame Horns. Unbolt each of the Front Bumper Mounting Brackets from the Front Bumper.
2. Drill the triangular pattern of holes on Frame Horns and Front Bumper Mounting Brackets to 9/16” diameter.
3. Position the PUSH BEAM SUPPORT PLATES (Ref. 62A and 62B, Fig. 1) and Front Bumper Mounting Brackets on the Frame Horn and attach using ―” – 13 x 2” HEX HEAD BOLTS, ―” – 13 HEX HEAD SELF LOCKING NUTS, and ―” FLAT WAHSER as shown in Figure 1. Note that 3 bolts attach through the side of the Frame Horn, and one bolt through the top of the Frame Horn.
4. Position the PUSH BEAM (Ref. 62, Fig 1) between the PUSH BEAM SUPPORT PLATES using 5/8” – 11 x 2” HEX HEAD BOLTS and 5/8” – 11 HEX HEAD SELF-LOCKING NUTS.
NOTE: The proper height adjustment for the PUSH BEAM is approximately 15-―” from the ground to the center of the PUSH BEAM pin-receiving hole (See Figure 2).
5. Position the ANGLE BRACKET (RH) (Ref. 75R, Fig. 1) between the frame rail and PUSH BEAM SUPPORT PLATE. Bolt the ANGLE BRACKET to the PUSH BEAM SUPPORT PLATE using 5/8” – 11 x 2” HEX HEAD BOLTS and SELF-LOCKING NUTS.
6. Push the frame end of the ANGLE BRACKET tightly against the frame. Bolt the ANGLE BRACKET to the frame using 5/8” – 11 x 2” HEX HEAD BOLTS, 5/8” – 11 FLAT WASHERS and 5/8” – 11 SELF-LOCKING NUTS.
7. Install the ANGLE BRACKET (LH) (Ref. 75L, Fig 1) following the same procedure as steps 5 and 6 above.
8. Torque all fasteners to the values specified in Figure 3.

The torque values listed above are based on dry, coated bolts, variables such as oil, or other lubrications may appreciably alter these values and must be taken into consideration.
