Instructions for main checks and measures are
given in the following pages, in order to determine
whether the parts can be re-used.
Keep the big end bearing shells in their respective
housings and/or note down their assembly
position since, if reusing them, they will need to be
fitted in the position found upon removal.
Note down the assembly position of the top and
bottom main bearing shells since, if reusing them,
they will need to be fitted in the position found upon
removal.
ENGINE OVERHAUL
ENGINE REMOVAL AT THE BENCH
The
following
instructions
are
prescribed
on
the
understanding that the engine has previously been placed on
the rotating bench and that removal of all specific
components of the equipment have been already removed
as well. (See Section 3 of the manual herein).
The section illustrates therefore all the most important
engine overhaul procedures.
