5. Cylinder Lubricating Pump
5.1 General
Each cylinder has a self-contained cylinder lubricating pump (5, Fig. 2) installed on a
support in the rail unit (2, Fig. 3). All of the cylinder lubricating pumps are connected
to supply pipes in the rail unit. Servo oil flows into a collector pipe installed below the
rail unit.
Servo oil operates the cylinder lubricating pumps when the related control signals are
released from the ECS.
Note: If a cylinder lubricating pump becomes defective and the safety system
releases a slow-down signal, the fuel injection of the related cylinder
must be cut out (see 0510-1 Operation during Unusual Conditions).
The cylinder lubricating pump has a pump body, 4/2-way solenoid valve (1) and a
pressure transmitter (6).
Two bushes are installed in the cylinder lubricating pump. The low feed rate (LFR)
bush is installed on the adjustment screw (7). The high feed rate (HFR) bush is
installed in the storage position (2). For more data about these bushes and the
related change procedure, see 7218−1.
5.2 Function
When the ECS sends a signal to the 4/2-way solenoid valve (1) on one of the cylinder
lubricating pumps, the 4/2-solenoid valve operates, which causes an injection.
A specified quantity of high pressure cylinder lubricating oil is injected through the
outlet ports (3) of the cylinder lubricating pump. This high pressure lubricating oil flows
through the oil pipes (4) to the lubricating quills (5) on the related cylinder.
5.3 Cylinder Lubricating Pump − Bleed
To bleed the cylinder lubricating pump, the cylinder lubricating system must be ready
for operation (see 0140-1 Prepare the Cylinder Lubricating System).
To bleed the cylinder lubrication system, see paragraph 6 and the procedure given in
the Maintenance Manual 7218-1.
5.4 Cylinder Lubricating Pump/Components − Maintenance
For an overhaul, or a replacement of the cylinder lubricating pump, send the
pump/components to the manufacturer.
For faults, causes and repair procedures, see 0820-1 Operating Problems,
paragraph 2 Cylinder Lubrication, and the supplier documentation for the cylinder
lubricating pumps.
