Ch 6 Maintenance
A. G
enerAl
A regular maintenance schedule should be
established to obtain the best service and
reliability from the remote racking device.
Actual inspection and maintenance will
depend on individual application conditions
such as number of racking operations, time
between uses, and storage conditions. When
the remote racking device has been in storage
for an extended period of time, it must be
inspected and cleaned before being used. See
and
3) Remote Racking Device Inspection
.
A permanent record of maintenance work
and inspections should be kept. The degree
of record detail depends on the operating
conditions. The record should include the
dates and results starting from the date the
device is first put into service. Dates and
results of inspections and routine maintenance
activities should be recorded.

Inspect the remote racking device for loose or
damaged hardware or parts. Tighten any loose
hardware, and replace missing or damaged
hardware or parts.
When necessary, remove loose dust and dirt
from the remote racking device with a vacuum
cleaner, a clean, dry cloth, or an industrial type
wiper. DO NOT use an air hose to clean the
remote racking device. Dirt or grit may be
blown into critical parts, including bearings,
which will cause excessive wear of the parts.

Apply A-grease on the drive shaft, under the
spring, to prevent rusting and help ensure
proper operation.
Powell offers a complete lubrication kit
(Powlube-104) which contains all the lubricants
required for maintaining the remote racking
device. Powlube-104 consists of (1) A-grease,
(1) B-grease, and (1) C-oil. Prior to March
2014, Powell provided Powlube-101 and
Powlube-102 which contained (1) tube of
Anderol 757 or Rheolube 368A, (1) tube of
Mobilgrease 28 and (1) bottle of Anderol A456
oil.
For all previous lubrication requirements
Powlube-104, A-grease replaces Anderol
757 and Rheolube 368A, B-grease replaces
Mobilgrease 28, and C-oil replaces Mobil 1 and
Anderol 456.
