Maintenance
Drum/Reel Drive Assembly
Drive Bar and Pins
The drive bar and adjustable pins are what
deliver the drive forces to the drum/reel.
These components should be inspected each
time the drum/reel is changed, and prior to
operations.

The drive bar is attached to the drive shaft,
and it should be inspected, along with the
drive shaft, for any signs of bending or
damage. If any of these conditions exist, it
must be replaced prior to operations.

The drive pins should be inspected to
ensure that they move freely through the
drive bar slots.

The drive pins should also be inspected for
stripped threads, cracks, and bending.
Drive Couplings
The drive shaft seats into the drive couplings
on both sides of the machine. Each drive
coupling is split horizontally into two halves.
The top half of the coupling is removable with
four screws and an integrated handle. The
bottom half is designed to remain in place
and support the drive shaft as the rope drum
or conductor reel is loaded.

The Retaining Screws should be torqued
to 135 ft. lbs. after changing/installing
rope drums or conductor reels and prior
to operations to ensure they are tight and
that the coupling halves are secured.

The mounting screws that hold the
couplings to the drive motor(s), or motor
and
roller pad-
(PT-3500),
should be
inspected and torqued to 400 ft. lbs. in
accordance with the preventive
maintenance schedule.
WARNING: Loss of Limb/Death : System must be off
and tagged out prior to attempting any maintenance on
the drive assembly
