5.3-1 Cylinder Removal and
Installation (Continued)
9 For reassembly, reverse the above procedures except
for the following special instructions for the cylinder
anchor nuts and the bumper:
• Install the bumper. Tighten the self-locking nuts
to leave .050–.080 in. (1.3–2.0 mm) end play for
each capscrew. This clearance allows for cylinder
alignment during clamping without overstressing the
capscrews.
• Lubricate the cylinder rod threads, but threads and
spherical portion of nut with wheel bearing grease.
• Install the washer on the rod end with the beveled
side facing the lug.
• Engage the rod end into the lug.
• Tighten the rod end nut to a torque values below.
Prevent the rod from turning by using a wrench on
the hex washer.
25D, 35D, 40D, 50D – 150–175 ft.-lbs. (200–235 Nm)
70D, 80D, 100D – 225–250 ft.-lbs. (305–340 Nm)
NOTE: The rod end nut is being tightened against
the hex washer. The nut will not be tight against the
arm lug. This looseness allows for cylinder alignment
during clamping.
• Install the locking cap and cotter pin.
• Lubricate the bearing portion of the arm bars with a
thin film of chassis grease.
• Operate the attachment through several full cycles
to force air in the system to the truck hydraulic tank.
Check for leaks.
