OPERATING MANUAL FOR BUKH DV48ME ENGINES
Preparation before first start
1.
Pour lubricating oil through filling hole on top of valve cover.
Check that oil level is between the marks on the dipstick, placed at
the port side of the engine.
Check oil level as mentioned below:
a)
remove and wipe dipstick
b)
reinsert dipstick in the pipe
c)
withdraw dipstick, check oil level.
2.
Pour lubricating oil through dipstick hole on the top of reverse- and reduction gear
and check oil level as described in pos 1.
3.
Flexible sterntube: Lubricate the stuffing box with sterntube oil (outboard).
Unscrew the filler plug and pour in oil until the bearing is full.
Important:The stuffing box shall under no circumstances be force-lubrica-
ted.
These instructions are only valid for propeller equipment supplied by BUKH.
If other equipment is mounted, we refer to the instructions given
4.
We always recommend checking of oil level before start.
5.
Fill the fuel tank.
6.
Bleed the fuel system in the following way:
a)
Loosen the slotted screw B on the fuel filter and pump with the handle A on
the fuel lift pump until the fuel is free from air bubbles and runs out at the
slotted screw.
b)
Tighten the slotted screw B and continue pumping with the handle A until
fuel, free from bubbles, runs through the transperent hose from fuel pump to
tank.
You must lock the pumping handle in the upper position when you
have finished pumping.
c)
Loosen the fuel pressure pipes at their connection on the fuel valves and
turn the engine by the starter motor until fuel, free from bubbles, runs out
from the fuel pressure pipes. Finally tighten the pipes and the engine fuel
system is ready for use.
Normally it will not be necessary to bleed the fuel system before starting but
after changing the fuel filter element or carrying out any work on the fuel system
it should be bled in the following way: Loosen the bleed screw and operate the
hand priming lever on the fuel lift pump until air-free fuel discharges from screw.
Tighten bleed screw. Loosen high pressure pipe unions to injectors and turn
engine until fuel discharges from pipes. Reconnect pipes to injectors. The
engine will start in the normal way.
