1. Replace the right side radius arm bracket fasteners.
NOTE:
THE SPECIFIED FASTENERS AND TORQUE REQUIREMENTS MUST BE USED. SEE FIGURE 2 FOR A DESCRIPTION OF PARTS CONTAINED IN THE RIGHT SIDE RADIUS ARM BRACKET KIT (E8TZ-3L095-A). REPLACE ONE (1) RIVET AT A TIME TO MAINTAIN BRACKET LOCATION.
a. Start with rivet # 1 (Figure 1). Drill a 3.175 mm (1/8") hole through the middle of the rivet.
b. Drill the same hole with an 11/32" drill.
C. Use an air chisel to remove the rivet head.
d. Drive the rivet out with a punch.
e. Line ream the # 1 rivet (Figure 1) hole in the frame web to a 12.7 mm (1/2") diameter.
f. Install a 1/2" Grade 8 bolt. The bolt head must be on the inboard side of the frame. Install a 1/2" hardened washer on the outside of the bracket. Install the nut and tighten to 142 N.m (105 lb-ft). Refer to Figure 2.
g. Remove the # 2 rivet (Figure 1) using Steps a through d.
h. Line ream the # 2 rivet (Figure 1) hole on the frame flange to a 14.288 mm (9/16") diameter.
i. Install a 9/16" Grade 8 bolt. The bolt head must be on the inboard side of the frame flange. Install a 9/16" hardened washer on the outboard side of the bracket. Install the nut and tighten to 190 N.m (140 lb-ft). Refer to Figure 2.
j. Repeat Steps h and i for the # 3 (Figure 1) rivet.
NOTE:
