to the trigger (21) and remove the valve spool assembly and
spring (22).
5. Knock out the roll pin (20) which holds the trigger to the
valve body and remove the trigger.
6. The flow regulator cartridge (30) may be removed by
placing a wrench on the hex flats and unscrewing the
cartridge assembly. The flow regulator cartridge is preset and
is not field ser-viceable.
7. Pry out the 2 o-rings (23), the 2 o-rings (12) and discard
them.
GRINDER REASSEMBLY
VALVE HANDLE REASSEMBLY
1. Apply grease and install 2 o-rings (23). Grease and install
2 o-rings (12).
2. Install the flow regulator cartridge (30).
3. Apply grease to the outer surface of the valve spool
assembly and install it into the valve body as shown in the
parts drawing.
4. Place the spring (22) and trigger (21) over the valve spool.
Align the roll pin hole in the valve spool with the roll pin hole
in the trigger and install the roll pin (20).
5. Align the roll pin hole in the trigger with the roll pin hole in
the valve body and install the roll pin (20).
OIL TUBES AND DIPPED TUBE
REASSEMBLY
1. Apply grease to 2 o-rings (12) and install them into the oil
ports of the rear bearing retainer (16) of the motor.
2. Apply grease to the end of each oil tube (9) and insert one
end of each tube into an oil port in the rear bearing retainer of
the motor.
3. Slide the dipped tube (10) over the two oil tubes and align
the fastener holes with those in the motor. Apply 242
Loctitetm and install the 8 capscrews (8). Tighten to 68-75
in. Ibs.
4. Place the valve handle (24) over the other end of the oil
SERVICE
tubes making sure the tubes are not twisted and are aligned
with the correct ports (directly in line with ports in the valve
handle and motor). Push the valve handle onto the oil tubes
and into the dipped tube until the valve handle is up against
the end of the dipped tube. Some wiggling of the handle may
be required to success-fully perform this procedure. Apply
242 Loctitetm and install the 2 capscrews (11). Tighten to
68-75 in. Ibs.
5. If removed, reinstall the hoses and couplers (female
coupler to the "IN" port, male coupler to the "OUT" port).
SPINDLE & SPINDLE HOUSING
1. Lubricate the needle roller bearing (52) thor-oughly with
lithium based grease for extreme pressure applications and
containing an NLGI rating of 2. Install the bearing into the
spindle housing (49) using an arbor press.
2. Apply grease and install the seal (53) into the spindle
housing, on top of the needle roller bear-ing, with lips facing
down.
3. Lubricate the bearing (34) thoroughly with lithium based
grease for extreme pressure applica-tions and containing an
NLGI rating of 2. Install the bearing onto the motor end of the
spindle (33) using an arbor press. Secure the bearing in
place with the retaining ring (35).
4. Install the bearing race (48) onto the spindle using an
arbor press. Lubricate the outer surface of the race with the
lithium grease used for the needle roller bearing.
5. Install the spindle (threaded end first) into the motor end of
the spindle housing. Using an arbor press, press the spindle
into the spindle housing until the bearing butts against the
bottom of the bearing bore.
6. Install the bearing spacer (36) into the spindle housing.
7. Apply grease and install the v-ring seal (50) onto the
spindle with the beveled side facing toward the threads of the
spindle.
8. Lubricate the coupling (37) and coupling ends of the
spindle and motor shaft with the extreme pressure lithium
grease. Install the coupling onto the spindle and then install
the completed spindle and spindle housing assembly to the
motor being careful to assure the coupling is aligned with the
motor shaft and spindle. Secure the assembly in place with
the 3 capscrews (51).
