1.
Remove, clean,
and
pressure test the primary heat exchanger.
(A
local automotive radiator shop
should
be
able to clean
and
test the heat exchanger.)
NOTE:
Operating
in
silty
and/or
tropical waters may require
that
a heat exchanger
cleaning
be
performed more often
than
every 1000 hours.
*2. Check the injection pump's timing.
(Static method spill time.)
A.
Rotate the engine's crankshaft to position the #1 piston
at
the
Top
Dead
Center
of
its compression
stroke. Observe the opening
and
closing
of
the valves for this cylinder so
as
not to place
the
piston
at
IDC
of
the exhaust stroke.
Align
the
IDC
mark
on
the crankshaft front pulley with the timing
marker
on
the front
gear
case
cover
when
positioning
the
# I Piston
at
TDC
of
its compression stroke. Confirm this by rotating
the
crankshaft approximately 20
0
before
and
after this point and
the
two valves for the # I cylinder should
not
move.
Adjust the valve clearances for both the intake and exhaust valves for this cylinder
