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.

(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.
