Cylinder Head Removal and Installation".
3) Mark cylinder number on all pistons, connecting rods
and connecting rod caps using silver pencil or quick
drying paint.
4) Remove rod bearing caps.

These guide hoses protect crank pin and threads of
rod bolt from damage during installation of
connecting rod and piston assembly.
