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 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
