new fuel injection pump before being put into use should be filled with
proper lubricant, because it can
’
t be lubricated before engine provides
the lubricant. Refer to the engine maintenance interval to service the
fuel injection pump by loosening the bolts at the back housing of it to
drain the used lubricant. After that, tighten the bolts and refill the new
lubricant.
b.
For the fuel injection pump non-forcedly lubricated (for example: P9
series pump), fill it with the stipulated-grade oil to the proper level
measured by a dipstick. That can lubricate the fuel injection pump with
engine running. Refer to the engine maintenance interval to service the
fuel injection pump by loosening the bolts at the back housing of it to
drain the used lubricant. After that, tighten the bolts and refill the new
lubricant.
5.1.4 Adjust the fuel injection advance angle
After the fuel injection pump is installed, refer to the engine requirements to
adjust the fuel injection advance angle. Namely, the piston of 1
st
cylinder
should be at optimal injection position before TDC. Loosen the high-pressure
fuel pipe of 1
st
cylinder connected to the fuel injection pump and bolts
attached to the fuel injection pump flange and couplings. As you crank the
pump or camshaft, observe where engine flywheel scale is when the fuel is
just the fuel out coming from the 1
st
cylinder. Refer to the requirements for
fuel injection advance angle for adjustment, and then tighten the loosened
bolts and joints.
5.1.5 Seal up for safekeeping
When the fuel injection pump is not used for long time, anti-rust treatment
should be done. Change the fuel and lubricant in the pump with anti-rust oil,
cover the joint of fuel/oil return pipe and reseal it once very year.
5.1.6 Precautions
a.
Without some experience and testing conditions, it is prohibited to
dismantle the fuel injection pump assembly at will in particular the lead
sealing parts which can
’
t be unsealed.
b.
The fuel injection pump should be stored in the vent and dry garage and
kept away from the chemical goods which can lead to corrosion and rust,
such as battery and acid.
