Removing the Shells

Take out lower bearing shell and make sure that its

lug is provided with a marking on the back.

NIf upper shell (14) cannot be pushed out by hand,

insert driver pin (15) into oil passage 'X' of crankshaft

(1) and carefully turn crankshaft in the arrowed direc-

tion (Fig. 5) until the flat of pin (15) contacts the joint

of upper shell (14). Carefully turn farther until the

upper shell can be removed by hand. Inspect upper

shell for the lug marking (see job 02.08.01). Provide

mark if missing. Remove pin (15).

To keep dust, etc., out of the crankshaft oil passage,

close the holes with a non-transparent adhesive

tape, so that it will be noticed for removal when

reassembly is done.

Shell wear patterns: See Job Card 02.04.01.
