Lubricate the valve seat with a little
polishing
paste
and
(Caution: do not allow the polishing paste to
enter the valve guides).
After polishing, flush valves and valve seats
with clean fuel and dry. Check the valve
tightening by spilling a small amount of fuel
into the suction and exhaust, observing
whether it leaks around the valve seats.

procedure.
Remove coal deposits, if any, and clean
with clean fuel. It may not be necessary to
disassemble for cleaning if the engine.
Clean the center hole of the axle pin and the
oil passages on the crankshaft shaft with
clean fuel.
Fill the water passages with a 25%
concentration of hydrochloric acid (HCl),
hold for about 10 minutes and then blow-
rinse with fresh water. Repeat if not
completely clean.
Note: The radiator must be removed from
the engine before cleaning.
Check the fuel injection pressure and spray
gun. Usually, the spray has a pattern of 4
concentrated jets and no fuel drip or spray
jet. If necessary, clean the coupling of the
nozzle and remove the coal deposits inside
the injection holes with a 0.3 mm needle. In
case of dripping of fuel and no clear
"trepidation" during spraying, it is necessary
to polish the coupling surfaces of the
coupling of the nozzle with a little polishing
paste. Then wash and reassemble. Reset
the fuel injection pressure again.
