NSTALLATION
STEP 5-Installing the Rear Pivot Arm Assembly
(Tools required–Two 1/2” wrenches.)
1. Select one rear pivot arm along with four 1/16-18 x .75” long
screws, four 5/16-18 lock nuts, two plastic cap brackets,
four flangettes, and two 1” ID bearings. (See figure 3-13.)
2. Rotate the pivot arm assembly into position. To do so, put
one pivot shaft of pivot arm through on pivot bracket, then
twist and rotate the shaft until it fits into the other pivot
bracket. Make sure the bumper attachment is towards the
front of the unit. (See figure 3-14.)
3. Each bearing set includes one 1” ID bearing and two
flangettes. Slide both bearing sets onto the pivot shaft with
the extended race facing toward the inside. (See figure 3-
15.)
4. Slide both plastic cap brackets. (See figure 3-16.)
5. Slide the four 5/16-18 x .75” long screws through the holes
in the plastic bracket, flangette, and mounting bracket. (See
figure 3-16.)
6. Attach the four 5/16-18 lock nuts and leave loose.
7. Adjust the position of the rear pivot arm assembly by first
positioning the 1” diameter protrusion at the end of the arm
against the inside edge of the side tube and then rotating
the pivot shaft to be parallel with the center tube. (See figure
3-17.)
8. Tighten the four 5/16-18 lock nuts to 15 ft-lb minimum. (See
figure 3-18.)
