4. Disassembling the cylinder ass’y
(1) Disassembly of the slip clutch ass’y
Remove the tool retainer ass’y and pull out the Cylinder [20] ass’y from the Gear Cover [7]. Remove
Washer (A) [25] from the Cylinder [20] and then use the retaining ring puller to pull out the Retaining Ring
for D30 Shaft [26]. Washer (A) [25], Spring (A) [24], the Second Gear [23], Cylinder Clutch [22], and Pin
D2.5 [21] can now be removed from the Cylinder [20].
(2) Disassembly of the cylinder inside
Insert stopper ring jig (A) (J-341) into the Cylinder [20] from the non-hole side as shown in Fig. 4 until it
contacts the end of the Damper Holder [34]. Clamp the ends of the Cylinder [20] and stopper ring jig (A)
(J-341) with a vise to compress Damper (A) [32]. (Push the Stopper Ring [35] with punch (C) (J-341) and
make sure it moves a little.) In this state, insert punch (C) (J-341) into each of the two ĭ8 holes on the
Cylinder [20]. Hammer the punch head to give force to the periphery of the Stopper Ring [35] in order to
detach the ring from the bore groove of the Cylinder [20]. Fully hammer along the periphery of the Stopper
Ring [35] until the Stopper Ring [35] disappears from the two ĭ8 holes.
Then unclamp the Cylinder [20] from the vise and use ring puller jig (B) (J-341) to pull out the Stopper
Ring [35] from the inner circumference of the Cylinder [20]. Be careful not to let the Stopper Ring [35] pop
out. Once the Stopper Ring [35] is detached from the Cylinder [20], Hammer Holder (C) [28], Sleeve (FW)
[29], the Second Hammer [30], Hammer Holder (A) [31], Damper (A) [32], O-ring (C) [33], and the
Damper Holder [34] can be removed from the Cylinder [20]. Here the Stopper Ring [35] is deformed by
disassembly and must be replaced by a new one when reassembled. Replace O-ring (C) [33] with a new
one at each disassembly to prevent dry firing.
