56) and rod stud (item 70). Remove connecting
rod (item 58).
8 Remove push rod (item 73) by pulling it toward
the center of the saw.
If the outer end of the push
rod is deformed, grinding may be necessary to
allow it to pass through the bushing (item 26).
9 Reinsert the small block of wood to stop rotation
of the crank arm (item 61). Insert 5/16 inch hex
key wrench into the drive shaft (item 63) and
turn clockwise to loosen and remove crank arm
(item 61).
10 Remove drive shaft (item 63).
11 Remove (4) screws (item 1).
12 Rotate gear housing (item 11), approximately 90
degrees relative to the motor housing (item 40).
Separate the housings by pulling or tapping
lightly with a rubber hammer.
13 Back off, but do not remove, (3) set screws (item
17).
14 Remove armature (item 76) by inserting two
screwdrivers between the gear housing and the
armature fan and gently prying.
15 Clean the gear housing cavity and the drive shaft
assembly to remove any contaminated lubri-
cant.
16 Remove (4) screws (item 8) and (1) screw (item
7).
17 Insert screw (item 1) into the center tapped hole
of the bearing cap (item 9) and tighten to remove
the bearing cap.
18 Turn the bottom up and push or tap it lightly to
remove drive shaft assembly (items 62-66).
19 Remove stator wires (item 81) from brush hold-
ers (item 37).
20 Remove (2) locknuts (item 78). Pull the stator
lead wires through the grommet hole and re-

toward the blade.
To reverse rotation, put stator
leads on opposite brush holders.

DRIVE SHAFT ASSEMBLY:
1 Place the drive shaft assembly assembly (items
62--66) into the gear housing (item 11).
Make
sure that the sub-assembly is completely bot-
tomed out in the bearing bore.
2 Place the armature sub-assembly (items 74--77)
into the gear housing.
Make sure that the sub-
assembly is completely bottomed out in the
bearing bore .
3 Grease the gear housing until it is 1/4 full.
4 Fasten the gasket (item 10) and bearing cap
(item 9) to the gear housing.
5 Lock the armature sub-assembly in place with
(3) set screws (item 17).
Do not over tighten the
screws as they may distort the bearing and cause
uneven rotation.
6 Assemble the motor housing (item 40) and the
remaining parts of the saw assembly to the gear
housing
with the exception of:
- crank arm and stud assembly (items 61 and
67)
- connecting rod and bearing assembly (items
58, 59 and 69)
- push rod (item 73)
