Lubrication
Always use an air line lubricator with this motor. We
recommend the following Filter-Regulator-Lubricator Unit
(FRL):
For USA - No. C22-04-G00
For International - No. C26-C4-A29
After each forty hours of operation
, or as experience
indicates, inject 1.5 cc of
Ingersoll-Rand
No. 28 Grease into
the Grease Fitting (44). Do not grease excessively. Too much
grease in the Gear Case will cause heating. Grease leakage
from the spindle end is also an indication that an excessive
amount of grease has accumulated within the Gear Case.
Installation
Always use clean dry air at 90 psig (6.2 bar/620 kPa)
maximum air pressure. Dust, corrosive fumes and/or
excessive moisture can ruin the motor of an air tool. An air
line filter can greatly increase the life of an air tool. The filter
removes the dust and moisture. Be sure all hoses and fittings
are the correct size and tightly secured. See Drawing
TPD905-2 for a typical piping arrangement.
(Dwg. TPD905-2)
It is important that the motor be serviced and inspected at
regular intervals to maintain safe, trouble-free operation of
the motor.
Tools, hose and fittings shall be replaced if unsuitable for
safe operation and responsibility should be assigned to
ensure that all tools requiring guards or other safety devices
are kept in operating condition. Maintenance and repair
records should be maintained on all tools. Frequency of
repair and the nature of the repairs can reveal improper
application or use. Scheduled maintenance by competent
authorized personnel should detect any mistreatment or
abuse of the motor and worn parts. Corrective action should
be taken before returning the motor for use.
When replacement parts are necessary, consult Maintenance
Section for part identification.
Maintenance Instructions
When removing a Spindle Planet Gear Shaft (50) from the
Spindle (48), always press it out so that it is ejected at the
short hub end of these parts. Likewise, when installing a
Shaft, start it into the narrow flange at the short hub end. This
is important, as the shaft holes are slightly tapered, so the
Shaft fits much tighter in the front, or wide, flange of the
Spindle.
Spindle Planet Gear Bearings (52) must be installed with
care to avoid distorting or fracturing the thin shell surrounding
the needles. Use a bearing inserting tool, as shown in
Drawing TPD786, when installing a needle bearing. Press
only on the stamped end of the bearing. Press one bearing
from each end of the hole when two bearings are used in one
gear. Never use one bearing as an anchor for installing the
second bearing.
Periodically check the Regulator Mounting Screws (29), Gear
Case Mounting Screws (46) and Adapter Mounting Screws
(55) for tightness.
