Operation
Drum/Reel Removal and Installation
When changing from a conductor reel to a rope drum, reverse the steps listed in this section.

The first step when changing from a rope
drum to a conductor reel or reconductoring
drum is to rotate the rope drum using the
joystick control, so that the drum hoisting
loop/bracket is at the top, the drive bar is
vertical, and the drive coupling split is
horizontal.

Turn off the engine and remove the key.

Attach the hoisting chain to the drum loops.

Next, loosen and remove the four bolts from
the top half of both the drive couplings on the
sides of the drive shaft, and remove the top
half of each drive couplings.

Once the top coupling halves are removed, lift
the rope drum up and off of the machine.

Lower the rope drum to a level surface on the
ground, and install chocks on both sides of
the drum to prevent it from rolling.

Loosen the set collars, set screws using a 5/16
inch hex driver or allen wrench, and remove
the set collar from the drive bar.

Once the set collars are removed, pull the
drive bar assembly out of the rope drum from
the drive bar side.

Insert the drive bar assembly into the
conductor reel or reconductoring drum,
leaving enough room to align the drive pins.

Adjust the drive pins so they align with the
holes
on the conductor reel or
reconductoring drum. To do this, loosen the
drive pin nuts using a 1 1/4 inch wrench, then
slide them up or down on the drive bar slot.
Once aligned, re-tighten the drive pin nuts jto
hold them in place in line with the holes.
NOTE: When transitioning from a rope drum to a
conductor reel, ensure that the rope end is secured
to the drum using a tie-off rope around the drum.
This will prevent the rope from paying out and the
rope end from being damaged.
CAUTION: It is highly recommended that the drum
be attached to the hoisting chains prior to
proceeding to the next step. This will help ensure
that the drum does not fall, damaging equipment or
injuring personnel, in the event of an accident.
NOTE: If these bolts are accidentally lost during
removal of the coupling, see the parts section to
order replacements. These bolts are specific 10.9
metric grade, 2.5 thread path, 20mm x 65mm bolts.
CAUTION: Do not operate machine with missing
drive coupling bolts. Do not attempt to use any other
size or grade bolts. These must meet OEM
specifications.
CAUTION: Ensure that all non-essential personnel are
clear of the area before lifting and moving the drum.
NOTE: It is not necessary to remove this set screw
all the way; however, if the set screw is accidentally
lost, the type/size is [Socket Head Cap, 3/8 in. x 1 in,
UNF]. Screws not sold separately, and if lost, full set
collar replacement may be necessary.
WARNING: Injury or Death: All personnel assisting
during the lifting of heavy loads must be wearing
appropriate personal protective equipment and
must remain vigilant and be ready to get clear in the
event of a load shift or restraint breakage.
NOTE: If it is required to rotate the drum lifting eye to the top for proper lifting, do this prior to turning off engine,
and attempt work with drive couplers.
CAUTION: The engine must be off and the key
removed prior to proceeding to the next step.
