Note: During usual operation, the ECS controls the cylinder lubricating pulses.
4) Manually release a lube pulse as follows:
a) Use a pin or a screwdriver (6, Fig. 1 ) to push in the plunger (7) of the 4/2-way
valve (3).
5) Look through the scavenge air ports in the cylinder liner (1) while the lubricating
system operates.
6) Make sure that the lubricating oil is correctly injected on to the cylinder liner wall
(refer to the Operation Manual 7218-1, paragraph 8.2 and paragraph 8.3).
7) Make sure that the oil that flows has no air. If necessary, bleed the cylinder
lubricating pump (4) and the oil pipes (2) (refer to paragraph 3 ).
8) Set to off the cylinder lubricating system for the related cylinder.
2. Cylinder Lubricating Pump
For data about the cylinder lubricating pump (4), refer to the Operation Manual
7218-1, paragraph 5.
2.1 Checks
1) Examine the cylinder lubricating pump (4) for damage and leaks.
2) Do a function check of the cylinder lubricating system (refer to paragraph
1.2 ).
3. Cylinder Lubricating System − Bleed
Bleed the cylinder lubrication pump and oil pipes each time you do maintenance on
the cylinder lubricating system.
3.1 Cylinder Lubrication Pump
To bleed the cylinder lubrication pump (4, Fig. 1 ), do the steps that follow:
Note: When you bleed the cylinder lubricating system, always start at the first
cylinder at the free end. The hydrostatic pressure in the cylinder
lubricating system helps you bleed the cylinder lubrication pump (4).
1) Make sure that the cylinder lubrication pump (4) is set to off.
2) Loosen the vent screw (5).
3) Keep the vent screw (5) open until oil that flows has no air.
4) Torque the vent screw (5) to 15 Nm.
5) Clean the external surface of the cylinder lubrication pump (4).
6) If necessary, bleed the oil pipes (2), (refer to paragraph
3.2 ).
7) Do a function check of the cylinder lubricating system, (see paragraph 1.2 ).
3.2 Oil Pipes
To bleed the oil pipes (2), do the steps that follow:
1) Set to on the cylinder lubricating system, (refer to paragraph
1.1 ).
2) Use an open-ended spanner to hold the screw-in union (8) in position.
3) Loosen the nut (9) of the screw-in union (8) a maximum of two turns.
4) Keep the nut (9) of the screw-in union (8) open until oil that flows has no air.
5) Tighten the nut (9) of the screw-in union (8).
6) Clean the external surface of the lubricating quill (10).
7) If necessary, bleed the cylinder lubricating pump (4) (refer to paragraph
3.1 ).
8) Do a function check of the cylinder lubricating system (refer to paragraph 1.2 ).
