MAINTENANCE PROCEDURES
34 4012/16 Gas, February 1998
NOTE: It is suggested that oil analysis tests
are carried out at regular intervals to check
that
these maintenance intervals are
satisfactory.
CHANGING ENGINE OIL AND
STANDARD SPIN-ON TYPE
LUBRICATING OIL FILTERS
With the engine stopped, place a suitable
container of at least 150 to 250 litres (33 to
55 gal) beneath the drain plug. Remove the
drain plug and allow the oil to drain. This
operation is best carried out while the
engine is still warm as the thinner oil will
drain more efficiently. While the oil is
draining remove the three oil filters per
bank, turning them anti-clockwise using a
strap wrench see
Fig. 22 .
NOTE: Removal of the oil filters will allow an
escape of oil from the filter manifolds, it is
therefore recommended that a suitable
container of at least 5 litres (1 gal) capacity
is positioned under each filter prior to
removal.
Wipe clean the sealing faces and threaded
bosses of the oil header. Smear engine oil
on the captive rubber sealing ring and
carefully screw each new filter up to the oil
header using firm hand pressure only.
Use only genuine Perkins oil filters. The use
of other filters may cause serious damage to
the engine.
Refit the drain plug and fill the engine with
the appropriate grade of new oil
(see pages
11-13 ) . Ensure that the gas supply is turned
off, also the switch on the control panel is in
the stop position, and
the ignition is
grounded to prevent the engine firing. Turn
the keyswitch to the start position, and crank
the engine over until the oil pressure gauge
registers 0.4 kg/cm² (5 lb/in²).
Continue cranking for a further 10 seconds
which will ensure the oil has reached the
turbocharger bearings.
See page 20 for instructions on priming with
the semi-rotary pump.
Stop cranking the engine and visually check
the engine for oil leaks, top up the oil level.
DISCONNECT
BATTERIES OR ANY
OTHER MEANS OF STARTING. ALWAYS
WEAR PROTECTIVE GLOVES.
