cap (5) and unscrew bolts completely. Remove cap
(5) out of crankcase. Take bottom shell out of cap (5).
Remove top shell when drawing the piston (Job Card

Scotch tape), cleaning rag or oil paper around the
crankpin to protect the oil bore against contaminati-
on.
Without piston removal
The top shell can also be removed with the piston
fitted. Remove support cap (5) as described under

square timber underneath piston.
Turn crankshaft slowly until the piston lowers onto
the square timber revealing the freely hanging con-
necting rod. Remove top shell.
