OUTRIGGERS 1300A
7-6 01-22-2019 Control # 051-08
Outrigger Beam Wear Pad Adjustment
Wear pad adjustment is as follows:
1. Remove the three hydraulic lines connected to the end
of the extension cylinder.
2. Place a bar under the end of the extension cylinder
barrel so that it can be lowered to the bottom of the
outrigger box.
3. Unbolt the end of the extension cylinder and lower it to
the bottom of the outrigger box.
4. Remove the wear pad set screw from the adjustable
wear pad.
NOTE: To turn the wear pad, use a flat blade about 3/16
inches (4.7 mm) thick and 1-3/4 inches wide
(4.4 cm) (Figure 7-6).
5. Screw the wear pad in until it stops and back off 1/2 turn.
Each 1/2 turn moves the wear pad about 1/8 of an inch
(3 mm) laterally.
6. Reinstall the wear pad set screw to keep the wear pan in
place.
7. Repeat for all wear pads inside the outrigger beam.
Outrigger Box Wear Pad Adjustment
1. With the outrigger fully retracted, attach the float to the
stabilizer and extend the stabilizer until the outrigger
beam contacts the top of the outrigger box.
2. Screw the bottom wear pads on the outrigger box (3)
(Figure 7-1) in and back off about 1/2 turn.
3. Screw the side wear pads on the outrigger box (2)
(Figure 7-1) in and back off about 1/4 turn.
Nonadjustable Wear Pad
Check the nonadjustable side wear pad on the outrigger box
(Figure 7-3). There should be a 0.06 in (1.5 mm) gap
between the outrigger box and wear pad. To correct the gap,
add or remove shims to the wear pad.
CAUTION
Keep hands out of the access hole when removing the
extension cylinder bolts. The barrel is free to drop when
the bolts are removed.
