Installation (Fig. 6)
1. If removed, install bearings onto rotor shaft:
A. Install inner retaining rings into shaft grooves if
they were removed.
B. Install bearings onto shaft by pressing on inner
race. Make sure that bearings are seated against in-
ner retaining ring.
C. Install outer retaining rings to secure bearings
onto shaft.
2. If rear cap was removed from inner housing, install
rear cap:
A. Slide rear cap (item 8) into housing.
B. Apply Loctite #242 (or e quivalent) to threads of
flange head screws ( item 4).
C. Secure rear cap to inner housing with flange head
screws (item 4). Torque screws from 90 to 100 in--lb
(10.2 to 11.3 N--m).
3. Install new O--ring (item 9) into inner housing. After
O--ring installation, clean O--ring to remove all oil,
grease or other material.
4. Position end cap (item 5) between bearings on rotor
shaft.
5. Install rotor shaft assembly into inner housing. Align
tab on end cap (item 5) and slot in inner housing as rotor
shaft assembly is being inserted into inner housing.
Make sure that end cap and bearing are fully seated in
housing bearing bore. Also, align holes in end cap with
threaded holes in inner housing.
6. Install bearing cap (item 4) into inner housing (Fig.
8):
A. Slide bearing cap (item 4) into inner housing.
Make sure that cap is fully installed onto rotor shaft
bearing.
B. Apply Loctite #242 (or e quivalent) to threads of
flange head screws ( item 4).
C. Secure bearing cap to inner housing with flange
head screws (item 7). Torque screws from 90 to 100
in--lb (10.2 to 11.3 N--m).
D. After tightening screws, make sure that rotor
shaft rotates freely.
7. Install rotor assembly (see Rotor Assembly Installa-
tion in this section).
8. Install blower drive shaft (see Blower Drive Shaft
Installation in this section).
9. Install top grill to machine (see Guards Installation in
the Service and Repairs section of Chapter 6 -- Chas-
sis).
10.Install nozzle pulley and nozzle to rear of outer hous-
ing ( see Nozzle Assembly Installation) in this section).
11. Connect negative battery cable to negative battery
terminal. Tighten nut that secures battery cable from 10
to 15 ft--lb (14 to 20 N--m). Make sure that battery cover
is secured.
