①
※
Draw out cylinder head and rod assembly
together from tube assembly (1).
Since the rod assembly is heavy in this
case, lift the tip of the rod assembly (3)
with a crane or some means and draw it
out. However, when rod assembly (3)
has been drawn out to approximately
two thirds of its length, lift it in its center
to draw it completely.
④
※
Loosen and remove socket bolts (25) of
the gland in sequence.
Cover the extracted rod assembly (3)
with rag to prevent it from being
accidentally damaged during operation.
③
※
Pull out rod assembly (3) about 200 mm
(7.1in). Because the rod assembly is
rather heavy, finish extending it with air
pressure after the oil draining operation.
