32. Fuel injection pump
NOTE! Any repair work required to be done on the fuel
injection pump should be carried out by specially trained
mechanics who have the necessary tools and testing
devices at their disposal. All warranty on the engine be-
comes null and void if the seals are broken by unauthori-
zed persons.
Since operating conditions vary considerably, it is difficult
to indicate any definite interval, but the pump settings, max.
and idle speeds, exhaust smoke, etc. should generally be
checked after every 2400 hours of operation.
Always check and clean the injectors and make sure that
the air lines to the turbo do not leak before checking the
engine exhaust smoke. The air cleaner should also be cle-
aned and the air lines must be free from constrictions.
In order to ensure even loading of the cylinders, the fuel in-
jection pump should be checked on a test bench. This is
extremely important with regard to engine life. This check is
preferably carried out in connection with the laying-up of
the boat at the end of the season.
33. Turbo-compressor
Check the turbo-compressor thoroughly after every 2400
hours of operation with regard to leakages of the oil lines
and air hoses. Check also the bearing clearance and char-
ging pressure as well as the general condition of the unit.
This check should be carried out by authorized personnel.
If necessary, replace the turbo-compressor with a new or
reconditioned unit.
Always fit new oil filters and change the engine oil when
replacing the turbo-compressor. Fill the turbo-compressor
bearing housing with 0.1 litre (0.1 quart) of oil before con-
necting the oil delivery pipe.
34. General checking
It is difficult to indicate a definite time for reconditioning the
engine since operating conditions vary considerably. By
measuring the compression pressure and observing the
consumption of lubricating oil it is, however, possible to
estimate roughly when the engine should be dismantled
and checked for wear.
In connection with a major overhaul of the engine, the re-
verse gear and reduction gear, if fitted, should also be
removed and checked for wear.
Cylinder heads and gaskets
Both cylinder heads have separate steel gaskets with spe-
cial rubber seals for sealing against water and oil.
A used gasket must never be refitted. Always fit a new gas-
ket. The cylinder head bolts should be tightened with a tor-
que wrench and in the correct sequence by personnel from
an authorized service workshop.
The valve clearance should always be adjusted after the
cylinder heads have been tightened.
