3) Retighten the bearing cap bolts by 6065 in the
numerical order shown.
Tightening torque
Main bearing cap bolt:
30Nm (300kgf.cm,22lbf.ft)+60˚~65˚
4) Check that the crankshaft turns smoothly.
9. Check crankshaft end play.
10. Install piston and connecting rod
assemblies.
NOTE: Before installing the pistons, apply a coat of
engine oil to the ring grooves and cylinder bores.
1) Remove the connecting rod caps, and slip short
sections of rubber hose over the threaded ends
of the connecting rod bolts.
2) Install the ring compressor, check that the
bearing is securely in place, then position the
piston in the cylinder, and tap it in using the
wooden handle of a hammer.
3) Stop after the ring compressor pops free, and
check the connecting rod-to-check journal
alignment before pushing the piston into place.
4) Apply engine oil to the bolt threads. Install the
rod caps with bearings, and torquethenuts:
50~53Nm(500~530kgf.cm,36.9~39lbf.ft)
NOTE: Maintain downward force on The ring
compressor to prevent the rings from expanding
before entering the cylinder bore.
11. Install a new gasket and rear oil seal case (A)
with 5 bolts (B).
Tightening torque
10~12Nm (100~120kgf.cm, 7.3~8.8lbf.ft)
NOTE: Check that the mating surfaces are clean
and dry.
12. Install rear oil seal.
1) Apply engine oil to a new oil seal lip.
2) Using SST (09231-21000) and a hammer, tap
in the oil seal until its surface is flush with the
