Reassembly can be conducted by reversing the disassembly procedure. However, special attention should
be given to the following items.
1. Reassembly of the hammering mechanism and low vibration mechanism
(1) Mounting the first gear and crank shaft
(a) Press-fit Oil Seal
[124] {134}
to the Crank
Case
[125] {135}
. Mount the O-ring (F)
[107] {106}
. Press-fit the Ball Bearing
6204DD
[106] {105}
. Use a retaining ring
puller to mount the Retaining Ring for D47
Hole
[105] {104}
. Press-fit the Crank Shaft
[103] {102}
to the Ball Bearing 6204DD
[106] {105}
.
(b) Insert the Feather Key
[104] {103}
into the
Crank Shaft
[103] {102}
groove. Support
the plane of the Crank Shaft
[103] {102}
with an adequate steel rod and use an
adequate tool to press-fit the First Gear
[139] {149}
. Simillarly press-fit the Second
Pinion
[140] {150}
.
NOTE: Prior to press-fitting, make sure
the Feather Key [104] {103}
matches the key groove of the
First Gear [139] {149} and the
Second Pinion [140] {150}.
(2) Mounting the piston
(a) Insert the Connecting Rod
<50>
into the Piston
<49>
and then press-fit the Piston Pin
<48>
into the
D10 hole (marked “
ĭ
2”) of the Piston
<49>
. Then mount the O-ring
<47>
on the Piston
<49>
to
complete the piston ass’y.
NOTE: Be careful not to let the Piston Pin <48> project from the outer diameter of the Piston
<49>.
(b) Next, turn the Crank Shaft
[103] {102}
to the position shown below, and then mount the piston
ass’y to the Crank Shaft
[103] {102}
from the Cylinder Case
<18>
side of the Crank Case
[125]
{135}
. Use a retaining ring puller to fix the Retaining Ring for D12 Shaft
[102] {101}
.
