9-2. Reassembly
Reassembly can be accomplished by following the disassembly procedures in reverse. However, special
attention should be given to the following items.
(1) Reassembly of the Crank Shaft
[47]
section:
Press-fit the Ball Bearing 6205DDCMPS2L
[44]
into the Inner Cover
[42]
, and fasten the Bearing Cover
[45]
onto the Inner Cover
[42]
with the four Seal Lock Hex. Socket Hd. Bolts M5 x 16
[46]
. Support the inner race
of the Ball Bearing 6205DDCMPS2L
[44]
with an appropriate jig, and press-fit the Crank Shaft
[47]
into the
ball bearing. Next, insert Distance Ring (B)
[41]
and the two Woodruff Keys 4 x 16
[71]
into the Crank Shaft
[47]
, and press-fit the Final Gear
[40]
and the Ball Bearing 6302VVCMPS2L
[39]
with a hand press.
(2) Reassembly of the Armature Ass'y
[75]
:
Press fit the Ball Bearing 6203DDCMPS2L
[68]
into the Inner Cover
[42]
, and fasten Bearing Cover (A)
[67]
onto the inner cover with the three Seal Lock Hex. Socket Hd. Bolts M5 x 16
[46]
.

Disassembly procedures are illustrated in Fig. 7. Pull the Stop Lever
[10]
outward in the direction indicated by
the arrow, and turn it slightly so that its end surface comes to rest on the flange portion of the Front Cover
[8]
.
Next, turn the Spring Case
[5]
so that the holes of the Spring Case
[5]
are aligned with the Needle Roller
[11]
.
Then, push in Damper (B)
[7]
with flat-blade screwdrivers to compress the Lever Spring
[6]
. Finally, while
keeping the lever spring compressed, fit a 3 mm dia. or less steel rod into the hole of the Spring Case
[5]
, and
push out the Needle Roller
[11]
. The Stop Lever
[10]
, Damper (B)
[7]
, and the Lever Spring
[6]
can then be
taken out.
(3) Reassembly of the Striker
[24]
: (Two possible methods)
A. After the Connecting Rod Ass'y
[31]
has
been assembled into the Housing Ass'y
[49]
, mount the Piston
[30]
and press it
into the Striker
[24]
.
B. Mount the Piston
[30]
onto the Connecting Rod
Ass'y
[31]
, and push down on the Connecting Rod
Ass'y
[31]
to press the Piston
[30]
into the Striker
[24]
.
Push
Either of the two methods described above requires a pressing force of more than 30 kg. When a "hissing" sound
is heard, the piston is properly inserted in the striker. (The "hissing" is the sound of the compressed air escaping
from the striker when the piston reaches the respiratory chambers within the striker.)
