Removing connecting rod caps
Open the inspection hatches, remove the connecting
rod caps. For identification, mark the removed con-
necting rod bearing with cylinder number and upper
or lower shell.
IMPORTANT! Handle bearings with care.
Removing pistons
Preparations
Use a cloth or oil paper to remove all carbon deposits
from the upper areas of the cylinder liner.Carbon de-
posits make it difficult to pull the piston out.
Removing pistons in right bank cylinders
1. Turn the crankshaft to bring the piston assembly
(from which the connecting rod cap has been re-
moved ) to top dead center.
2. Turn the crankshaft in reverse until the crank pin
comes off the connecting rod and the bolt hole of
the rod is visible through the inspection hatch on
the side of the crankcase.
3. Cover a bar with a cloth for protection. Put the tip
of the bar under the bottom of the big end of the
connecting rod and pry the bar slightly down-
wards using the crank pin as a fulcrum. This will
push the piston assembly upwards.
NOTE! If you insert the turning bar too far, you may
not be able to pry the piston assembly upwards. In-
sert the bar 10 to 20 mm [0.39 to 0.79 in.] beyond the
big end.
