Use wrench flat on rod under spacer (if

4. Continue to turn rod into rod end until tilt cylinder
strokes are equal.

The rod must he threaded onto the rod-end
yoke a distance at least as great as the diame-
ter of the rod plus 6.5 mm (0.25 in).
5. Tighten capscrew of the rod-end yoke to 166- 193
N.m (122-142 ft-lb), and repeat the racking test.
6. Repeat steps 1-5 for fine corrections if any racking
remains evident.
7. When no racking occurs, retighten capscrew of the
rod-end yoke to 166-193 N⋅m (122-142 Et-lb).
8. Check all tilt functions before returning the truck to
service.
Backward Adjustment
Perform forward check and adjustment first. Then:
1. Slowly tilt upright fully backwards while watching
piston rods. They should both bottom out at the same
time. If they don’t, adjust backward tilt using the fol-
lowing steps.
2. Stop the upright when the first tilt cylinder bottoms
out against its rod spacer.
3. Go to the opposite cylinder and remove the capscrew
on the rod-end yoke and screw rod out of yoke.
Count the number of turns required to remove the rod
from the yoke.
4. Use rod shims to fill in the space between the rod-
end yoke and spacer. Screw rod back into yoke the
same number of turns needed to remove.
5. Tighten capscrew of the rod-end yoke to 166-193
N⋅m (122-142 ft-lb), and repeat the racking test.
6. Repeat steps l-5 for fine corrections if any racking
remains evident.
7. When no racking occurs, retighten yoke capscrew to
166-193 N⋅m (122-142 ft-lb).
8. Check all tilt functions before returning the truck to
service.
