SECTION 4 - BOOM & PLATFORM
3121142 – JLG Lift – 4-31
4. Install the fly boom section partially into the outer mid
boom section.
DO NOT ALLOW THE FLY BOOM TO REST ON THE FOUR EXTEND WIRE ROPES
WHILE INSERTING IT INTO THE OUTER MID BOOM.
5. Apply JLG Threadlocker P/N 0100011 to the bolts and
install the front lower wear pads and shims to the outer
mid boom as marked during disassembly. Torque the
bolts to 50 ft.lbs. (68 Nm).
6. Install the fly boom section most of the way into the
outer mid boom section, leaving enough of the fly out
so there is adequate slack in the fly boom extend cables
to allow for installation of the front sheave.
7. Install the sheave, bushings, pin, keeper pin, and retain-
ing bolt to the front of the outer mid boom section.
8. Install the cable retainer blocks and shims.
9. Apply JLG Threadlocker P/N 0100011 to the bolts and
install the front upper, and side wear pads on the outer
mid boom section as marked during disassembly.
Torque the bolts to 50 ft.lbs. (68 Nm).
