cylinder tubing, extend cylinder tubes and

bulkhead fittings in support plate, Fig. 3.8,

below the rear opening of the boom.

7. Loosen clamps that hold the tubing to the

bottom of the outer boom and remove the

tubing from the outer boom.

8. Attach slings and a suitable hoist to the

approximate center of gravity of the outer boom

and remove all slack from hoist cable.

NOTE: The approximate center of gravity of the

outer boom will be closer to the rear of the outer

boom.

9. Refer to Fig. 3.7 and remove the locknuts and

capscrews that secures the hoist cylinder rod

end pins. Remove the pins. Check the

13. Check the condition of both boom pivot main

frame bearings; replace if worn or damaged.

14. If the front outer boom wear pads, Fig. 3.9, are

excessively worn, temporarily replace them

with new pads. Use the same amount of

shimming as used when the pads were re-

moved.

IMPORTANT: The ends of wear pad attaching

capscrews must not protrude beyond the wear pad

insert; the ends must range from flush to 0.19"

(5 mm) recessed in the wear pad insert (refer to

Fig. 3.3).

b. Inspection and Replacement

1. Inspect the boom and welds and contact JLG if

structural damage is detected.

2. Inspect hoses and replace if damaged.

3. Inspect and replace wear pads as described in

paragraph 3.1.8.

c. Installation

1. Using slings and a suitable hoist, align the

outer boom pivot collars with the main frame

bearings.

2. Install the boom pivot pins and washer spac-

ers, placing the spacers on the inside of the

frame bearing, Fig. 3.10. Using No. 10 and/or

14 gauge shims, shim to maintain a gap

between the frame bearing and outer boom of

0.07 to 0.13" (1,8 to 3,3 mm).
