Maintenance
Drum/Reel Drive Assembly
* PT-3500 Only :
The PT-3500 only has one drive motor, and therefore has a pillow block bearing
to support the other side of the drive shaft. See below for maintenance steps specific to this
bearing.
Tightening Set Screws
Each side of the pillow block bearing-
(inside/outside) has two set screws for a total
of four.

The four set screws should be tightened
using a 3/16 in. hex key or allen wrench
any
time the drive shaft is
removed/replaced.

The set screws should also be inspected to
ensure they are in place and tight prior to
operation.
Greasing Pillow Block Bearings
The pillow block bearing must be properly
lubricated with lithium base Grade 2 all-
purpose grease according to the preventive
maintenance
schedule-
(see Preventive
Maintenance Schedule section).

Apply grease to both the inside and
outside grease fittings.
NOTE: In extreme hot or cold climates, a heavier or
lighter grade grease may be required.
WARNING: Loss of Limb/Death : System must be off and tagged out prior to attempting any maintenance on the
drive assembly
.
NOTE: The set screws hold the drive shaft snug to the
inside of the pillow block bearing eliminating gapping
between the drive shaft and the bearing. This also
helps to prevent drum hop.
