each. If dowel pin is not available (when reusing crankshaft and
signal), use M6 bolt [length 10 mm (0.39 in) or more] as a substi-
tute.
5. Install crankshaft to cylinder block.
While turning crankshaft by hand, make sure that it turns smoothly.
6. Install lower cylinder block with the following procedure:
a. Apply liquid gasket with a tube presser (special service tool:
WS39930000) to lower cylinder block as shown in the figure.
Use Genuine Liquid Gasket or equivalent.
CAUTION:
After liquid gasket is applied, rear oil seal installation must
be finished within 5 minutes. Therefore, the following pro-
cedure must be performed quickly.
NOTE:
Lower cylinder block cannot be replaced as a single part,
because it is machined together with cylinder block.
b. Tighten lower cylinder block mounting bolts with the following
procedure:
i. Apply new engine oil to threads and seat surfaces of mounting bolts.

i. Tighten M10 bolts in numerical order from No. 1 to 10.
ii. Turn M10 bolts 60 degrees clockwise (angle tightening) in order
from No. 1 to 10 in the figure.
CAUTION:
Check and confirm the tightening angle by using an angle
wrench (special service tool) or protractor. Avoid judgment
by visual inspection without the tool.
After installing mounting bolts, make sure that crankshaft can be rotated smoothly by hand.
Wipe off completely any protruding liquid gasket on front side of engine.
Check crankshaft end play. Refer to EM-107, "CRANKSHAFT END PLAY" .
7. Install piston to connecting rod with the following procedure:
a. Using snap ring pliers, install new snap ring to the groove of the piston rear side.
Insert it fully into groove to install.
b. Assemble piston to connecting rod.
Using an industrial use drier or similar tool, heat the piston until the piston pin can be pushed in by hand
without excess force [approx. 60 to 70 °C (140 to 158 °F)]. From the front to the rear, insert piston pin
into piston and connecting rod. : 25.1 N·m (2.6 kg-m, 19 ft-lb)
