WHEN PUSHING THE TELESCOPE CYLINDER INTO THE BOOM, IT
MAY BE NECESSARY AT SOME POINT TO TURN THE CYLINDER
SLIGHTLY IN ORDER TO CLEAR ASSEMBLIES MOUNTED WITHIN
THE BOOM. CARE MUST BE TAKEN TO MOVE THE CYLINDER
SLOWLY INTO THE BOOM. DAMAGE TO COMPONENTS MAY
RESULT FROM FORCIBLE IMPACT WITH THESE ASSEMBLIES.
NOTE: The telescope cylinder weighs approximately 600
lbs. (275 kg).
9. Using adequate lifting equipment, carefully push the
telescope cylinder assembly and cables back into
the boom.
10. Apply Loctite #242 to the bolts and fasten the tele-
scope cylinder rod to the boom base section with
the bolts, shims, mounting blocks.
11. Apply Loctite #242 to the bolts and fasten the tele-
scope cylinder barrel to the boom mid section with
the bolts, shims, mounting blocks.
12. Using a 3/8 drive extension approximately 4 feet (1.2
m) long, install the bolts and washers securing the
cable mount block to the boom fly section. Tape the
bolts to the socket at the end of the extension to pre-
vent it from coming out of the socket before it
engages the mounting threads.
13. Connect all the hydraulic lines to the cylinder as
tagged during the removal procedure.
14. Adjust the boom cables as outlined under Section
4.3, Boom Rope Torquing Procedures.
15. Run the boom through all lift and telescope func-
tions and check for proper operation or any leakage.
