24) Remove the service hole cover and service
hole plugs using hexagon wrench [14 mm (0.55
in)].
25) Rotate the crankshaft to bring #1 and #2 pis-
tons to bottom dead center position, and then re-
move the piston circlip through service hole of #1
and #2 cylinders.
26) Draw out the piston pin from #1 and #2 pistons
using ST.

NOTE:
Be careful not to confuse the original combination
of piston, piston pin and cylinder.
27) Similarly remove the piston pins from #3 and #4
pistons.
28) Remove the bolts which connect the cylinder
block on the side of #2 and #4 cylinders.29) Back off the bolts which connect the cylinder
block on the side of #1 and #3 cylinders two or
three turns.
30) Set up the cylinder block so that #1 and #3 cyl-
inders are on the upper side, then remove the cyl-
inder block connecting bolts.
31) Separate the cylinder blocks (LH) and (RH).

13) Position the expander gap at (C) in the figure.
14) Position the lower rail gap at (D) in the figure.
15) Align lower rail spin stopper (F) with piston side
surface hole (E).16) Position the upper rail gap at (G) in the figure.
NOTE:
 Ensure ring gaps do not face the same direction.
 Ensure ring gaps are not within the piston skirt
area.
17) Install the circlip.
Install the circlips in piston holes located opposite
of service holes in cylinder block, when positioning
all pistons in the corresponding cylinders.
