11. Grasp the Collet Body, Arbor or Arbor Bearing Nut
and insert the assembled Rotor into the Motor
Housing (8).
12. Assemble the Flow Ring (21) with the Flange (22)
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. Do not make the
12,000 rpm models function as rear exhaust tools.
13. Install the assembled Flange, Flow Ring leading, onto
the front of the Motor Housing.
14. Grasp the Motor Housing in copper–covered or
leather–covered vise jaws with the Collet Body, Arbor
or Arbor Bearing Nut upward. Do not distort the
Housing.
15. Position the Flange Clamp (23) against the Flange.
Steps common to ALL HX models
1. Lubricate the Arbor Coupling (34) with
approximately 1 cc of Ingersoll–Rand No. 68 Grease
and position the Coupling over the Arbor Bearing Nut
(36). Position the Clamp Sleeve (35) over the Arbor
Coupling against the Front Rotor Bearing (20).
2. If the Rear Arbor Bearing (38) was removed, proceed
as follows:
a. Stand the larger piece of the LE2–950 Bearing
Inserting Tool on the table of an arbor press.
b. Place the Rear Arbor Bearing on the surface of the
Inserting Tool and align the central opening of the
Bearing with the central opening of the Inserting
Tool.
c. The large body of the Arbor (39) has an annular
groove between the crosshole and one threaded
end. Press that end of the Arbor into the Bearing
until the shoulder of the Arbor stops against the
Bearing.
3. If the Front Arbor Bearing (42) was removed from the
Arbor Housing (40), proceed as follows:
a. If the Rear Arbor Bearing was not removed from
the Arbor, insert a 5/32" (4 mm) hardened steel
rod approximately 6" (150 mm) long through the
crosshole and using a 1/2" wrench, unscrew and
remove the Arbor Bearing Nut (36) from the
Arbor. Do not remove the Bearing.

Steps common to ALL HXD models
1. Position the Clamp Sleeve (28) over the Arbor against
2. Thread the Arbor Housing (30) onto the Motor
3. Using snap ring pliers, install the Arbor Bearing
Steps common to ALL HD models
1. Position the Clamp Spacer (26) over the Arbor against
2. Thread the Clamp Nut (27) onto the Housing and
25
b. Stand the larger piece of the No. LE2–950 Bearing
Inserting Tool on the table of an arbor press and
insert the Arbor, Rear Arbor Bearing end leading,
into the central opening of the piece until the
Bearing stops against the top of the Inserting Tool.
c. Install the Arbor Housing, threaded end first, over
the Arbor until it stops against the Bearing and
pilots on the Bearing Inserting Tool.
d. Position the Front Arbor Bearing on the Arbor and
using the smaller piece of the No. LE2–950
Bearing Inserting Tool as a pressing tool and pilot,
press the Bearing onto the Arbor until it stops
against the arbor shoulder.
e. For models ending in G4, install the Arbor
Bearing Shield (42A) in the Housing against the
Bearing.
f. Using snap ring pliers, install the Arbor Bearing
etaining Ring (43) in the Arbor Housing.
approximately 6" (150 mm) long through the
