4.2.4 Disassembly of Cam Follower Section
Disassemble the cam follower
section (located at the upper area
of the nozzle shaft) from the
nozzle shaft as shown in Fig. E27.
Remove the two bolts (M1.6L3).
Follow the same procedure to
disassemble the cam followers for
the twelve nozzle shafts.
The disassembled cam
follower should be
kept so as to match the
nozzle No.
4.2.5 Detachment of Nozzle Shaft Assembly
(1) Remove the three screws (M1.6L5)
(marked "B" in Figs. E24 and E25).
(2) Pull down the nozzle shaft holding jig.
When the jig is kept too tight, try to
push several areas on the upper part of
the nozzle shaft by hand.
(3) Take out the nozzle shaft assembly,
keeping it in the condition shown in Fig.
E28.
Be sure not to drop the assembly.

the DD motor side with three screws
(M1.6L5). (Fig. E30)
(a) Align the cutout of the positioning
pin (located at the bottom of the
DD motor) with the cutout of the
nozzle shaft assembly side (Figs.
E31 and E32) and insert the

4.3.2 Assembly of Cam Follower Section
Assemble the cam follower section
(located at the upper area of the
nozzle shaft) to the nozzle shaft with
two bolts (M1.6L3). (Fig. E33)
Tightening Torque:
720 gf/cm
(Use Screw Lock 1401B.)
(a) Attach the nozzle
shaft and cam
follower vertically
without leaving any
clearance between
Face A of the cam
follower and Face B
of the nozzle shaft. (Fig. E34)
(b) In principle, the disassembled cam follower section and nozzle shaft must be
reassembled.
