ADJUSTMENT
1.
Level carrier using outriggers.
2.
Reeve cable on single part line over boom tip sheaves (TM 5-3810-305-10). Start engine. Fully extend boom
and raise boom to the fully raised position. Lower hook block so that it is 5 ft (1.5 m) off the ground.
NOTE
This procedure may require a load. Use approximately 500 lb (227 kg).
3.
Check hook block alignment. Adjust boom pads on sides of sections at front of lower section and rear
of tip section so that cable is hanging within the width of lower boom section by adding or subtracting shims
under pads.
4.
Lower boom fully. Stand at rear of boom and swing boom from side to side. Watch for side play between boom
base section and boom tip section. If there is an appreciable amount of play between sections, boom tip will
have to be reshimmed.
NOTE
See Steps 9 through 11 in Disassembly for locations of pads.
5.
If reshimming is required, check pad sets by measuring the gap between side wear pads and surface where
pad slides on. Add the gaps on both sides of boom together for each set of pads which are directly opposite
each other; the total gap should be 0.06 to 0.09 inch (1.5 to 2.3 mm) per set.
6.
Pad sets on front of boom base can be replaced without disassembling boom.
7.
To replace pad sets on boom extend cylinder and boom tip section, disassemble boom.
