Rod Bearing Cap
Install the piston and connecting rod assemblies.
NOTE:
Before installing the pistons, apply a coat of engine oil to the ring grooves and cylinder bores.
When installing the piston, ensure that the coat on the cylinder wall is not damaged or scratched.
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.
Stop inserting the piston when the ring inserted in the cylinder and check the alignment of the journal and the connecting rod.
Apply engine oil to the bolt threads. Install the rod caps with bearings, and torque the bolts.
Tightening torque 19.6 Nm (2.0 kgf.m, 14.46 ft. lbs.) + 90°
NOTE:
Always use new connecting rod bolts.
Maintain downward force on the ring compressor to prevent the rings from expanding before entering the cylinder bore.
