Installation
NOTE:
• Use new bearing cap No.1 bolts. They are
deformed once they are used because they
are plastic deformation tightening bolts.
• All parts to be installed must be perfectly
clean.
• Be sure to oil crankshaft journals, journal
bearings, thrust bearings, crankpins,
connecting rod bearings, pistons, piston
rings and cylinder bores.
• Journal bearings, bearing caps,
connecting rods, rod bearings, rod bearing
caps, pistons and piston rings are in
combination sets. Do not disturb such
combination and make sure that each part
goes back to where it came from, when
installing.
