Before performing the next step, be aware that the
Front Rotor Bearing is a double flush ground
bearing and must be installed in a specific manner.
The end of the Bearing with a black stain or hash
marks must be away from the Spacer.
4. Stand the Rotor on the table of an arbor press with the
threaded end upward and press the Front Rotor
Bearing (17) onto the hub of the Rotor.
5. Grasp the assembled Rotor in copper–covered or
leather–covered vise jaws with the threaded rotor hub
upward.
6. Thread the Bevel Pinion (21) onto the Rotor and using
a torque wrench, tighten the Bevel Pinion between 9
and 10 ft–lb (12.2 and 13.6 Nm) torque.
7. Inject approximately 0.7 cc of Ingersoll–Rand No. 68
Grease into the small recess at the bottom of the
motor housing bore. Drop the two Rear Rotor
Bearing Spacers (10) into the bottom of the motor
housing bore.
8. Wipe each Vane (13) with a light film of oil and insert
a Vane into each vane slot in the Rotor.
9. Grasp the Bevel Pinion and insert the assembled
Rotor into the Motor Housing (5).
10. Assemble the Flow Ring (18) with the Flange (19)
before installing the Flange on the Housing. Mate the
Flow Ring to the end of the Flange without
perforations. The positioning of the Flow Ring is
dictated by the desired exhaust. To set the tool
exhaust, proceed as follows:
a. For front exhaust tools, align the notched
projection on the edge of the Flow Ring with the
letter "F" on the Housing.
b. For rear exhaust tools, align the notched
projection on the edge of the Flow Ring with the
letter "R" on the Housing.
11. Install the assembled Flange, Flow Ring leading, onto
the front of the Motor Housing.
Assembly of the Angle Head
1. If the Upper Arbor Bearing (26) was removed and a
new Bearing must be installed, proceed as follows:
a. Support the machined face of the Angle Head (22)
on the table of an arbor press with the upper arbor
bearing bore upward.

is necessary to note the identification marks on the
Bearing. One side of the Bearing has black stains or
hash marks across the inner and outer races. Using a
sleeve that contacts the inner ring of the Lower Arbor
Bearing, press the Bearing, black stain or hash mark
side leading, onto the Arbor (31).
The Bevel Gear and Bevel Pinion in the next step
are specially matched sets. Some sets are color
coded for manufacturing purposes only. Only the
Gear and Pinion set furnished as a replacement
part or the same Gear and Pinion removed from
one tool, is a matched set. A Bevel Gear from one
tool used with a Bevel Pinion from another tool
with the same color code IS NOT A MATCHED
SET. Replace these parts only as a matched set.
Failure to do so will result in unsatisfactory tool
performance and damage to the Bevel Gear and
Bevel Pinion.

keys of the Gear with the slotted keyways in the
Arbor.
above the Bevel Gear and the threads in the Bevel
Gear Nut (28).
Apply a thin coat of Permalock HM118* (M. I.
Hernon Grade 427) to the threads of the Bevel Gear
Nut and the Nut threads on the Arbor. Thread the
Bevel Gear Nut onto the Arbor to retain the Bevel
Gear and tighten the Nut to 10 to 12 ft–lb (13.5 to
16.2 Nm) torque. Grease the Bevel Gear with 1.5 cc
of Ingersoll–Rand No. 67 Grease.
Form the Wick (27) into a horseshoe shape and fully
inset it into the U–shaped cavity in the Angle Head. If
installing one of the Wicks having a notch on one
side, make certain the notch enters the Housing first.
Saturate the Wick with approximately 1.5 cc of
Ingersoll–Rand No. 63 Oil. Do not substitute any
other oil.
