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.
5) Install guide hose (1) over threads of rod bolts.
This prevents damage to bearing journal and rod bolt
threads when removing connecting rod.
6) Decarbonize top of cylinder bore before removing
piston from cylinder.
7) Push piston and connecting rod assembly out
through the top of cylinder bore.
Installation
