Placing Tool in Service
Lubrication
Ingersoll Rand No. 50 Ingersoll Rand No. 28
Always use an air line lubricator with this motor.
We recommend the following Filter-Lubricator-Regulator Unit:
No. C28-04-FKG0-28
Where the lubricator cannot be permanently mounted, use
Ingersoll Rand No. 3LUB8 Lubricator.
We recommend the use of an air line lubricator in the air supply
line. Attach the unit as close to the tool as practical. For permanent
installations, we recommend using an Ingersoll Rand
C28-04-FKG0-28 Filter-Lubricator-Regulator Unit. These units have
1/2” pipe tap inlet and outlet. The 3LUB8 has 1/6 pt. (79 ml) capacity;
the C28-04-FKG0-28 has 11 oz (180 ml) capacity. Larger capacity units
may be used, but do not use a unit having less than 1/2” pipe tap
inlet and outlet.
After each 40,000 cycles or one month, whichever occurs first,
inject 1.5 cc of Ingersoll Rand No. 28 Grease into the Grease
Fitting (60).
Direction of Spindle Rotation
Series 4800 Non-reversible Motors can be assembled so that the
Spindle rotates either clockwise or counter-clockwise. To reverse the
direction of the spindle rotation:
1. Remove the motor assembly from the Motor Housing (10).
2. Remove one End Plate and Bearing assembly from the motor.
3. Lift the Cylinder (19) from the Rotor (17), turn it end for end, and
slide it back over the Rotor.
4. Install the End Plate and Bearing assembly on the Rotor Hub and
install the assembled motor in the Housing.
5. Remove the three Backhead Cap Screws (11) and rotate the
Backhead (2) and Backhead Gasket (3) 120° so that the cavity
in the face of the Backhead is in alignment with the alternate
set of holes in the back face of the Motor Housing. When the
Backhead is correctly applied, the cavity will be over the letter
“F” for counterclockwise spindle rotation (when facing the end
of the Spindle), and over the letter “R” for clockwise rotation. The
rotational direction of an assembled Non-reversible Series 4800
Motor can be determined by removing the Air Strainer (1) and
looking through the tapped opening to see whether the letter
“F” or letter “R” is visible. Apply the Backhead on Series 4840
Reversible Motors so that each inlet port aligns with a group of
three holes through the housing rear wall.
NOTICE
A four-way Throttle Valve (whether manually, remotely, or
automatically controlled) must be used in the air supply
line to Series 4840 reversible motors, as one motor inlet is
expelling secondary exhaust air, and therefore must be open to
atmosphere whenever the opposite inlet is admitting live air to
the motor. The use of any throttle valve that closes or restricts
the secondary exhaust line will result in sufficient back pressure
to drastically reduce the speed and power of the motor.
When the application requires a separate Throttle Valve in each
air line, the two three-way valves must be used.
