BOOM FOLDING CYLINDER REPLACEMENT - CONTINUED
INSTALLATION - CONTINUED
Procedure for ARMY and RESET vehicles
Operate boom folding cylinders to full extended position (TM 10-3930-675-10). Measure overall length of cylinder (8). If
measurement is the identical to that recorded prior to removal, adjustment may not be required. If measurement is not identi-
cal, cylinder adjustment is required.
Prior to making adjustments to boom folding cylinders, boom and tophandler must be installed and
boom should be raised to a 19 degree angle and extended to 110 in. (279 cm). Failure to perform this
step will result in equipment damage.
Ensure boom folding cylinders are operated to the full extended position. This will allow boom sup-
port locking pin cylinders to operate freely.
Measure overall length of cylinder (8). If measurement is identical to that recorded prior to removal, no adjustment is
required. If measurement is not identical, cylinder adjustment is required. Proceed to next step.
Adjust cylinder length by loosening two clevis clamping screws (10) at upper end of cylinder (8). Access cylinder piston
rod adjusting nut (9) through opening in boom support.
Turn adjusting nut to adjust overall length of cylinder. Tighten two clevis clamping screws. Proper adjustment is
achieved when two bushings (11) of folding boom support (12) are in perfect alignment with stationary bushing (13)
mounted in frame.
