2 Examine the cylinder lubricating pump as follows:
2.1 Do a check of the tightness of the non return valves (013) as follows:
2.1.1 Blow air trough the non return valves (013) with your mouth.
2.1.2 If from the two sides air comes out, clean the valve seat.
2.2 Do a check of the surface of the main bore for scores or other damage.
2.3 Do a check of the control edge (007) of the pump for scores or other damage.
2.4 Do a check of the plungers (014) for scores or other damage.
2.5 If there are scores or other damage, repair or replace the related part.
2.6 Do a check of the main piston (012) for free movement.
2.7 If there is no free movement, clean or replace the main piston (012).
3 Assemble the cylinder lubricating pump as follows:
3.1 If the air vent screw (010) is removed, apply Loctite No. 542 to the air vent screw
(010).
3.2 If the air vent screw (010) is removed, install the air vent screw (010). Make sure
that the exhaust hole points in the correct direction.
NOTE: In the operation position of the cylinder lubricating pump the hole must
point down.
NOTE: Do not tighten the air vent screw (010) too much.
3.3 Install the pressure transmitter (015) and torque it to 25 Nm.
3.4 Apply a thin layer of oil to the piston joint ring (009).
3.5 Install the piston joint ring (009) to the slide rod (008).
3.6 Install the slide rod (008) into the housing in the correct direction.
3.7 Apply a thin layer of oil to the main piston (012).
3.8 Install the main piston (012) into the housing in the correct direction.
3.9 Apply a thin layer of oil to the O-rings (003, 004).
3.10 Attach the O-ring (003) to the groove of the housing.
3.11 Attach the O-ring (004) to the groove of the pin (005).
3.12 Apply a thin layer of oil to the plungers (014).
3.13 Apply a thin layer of grease to the pin (005).
3.14 Assemble the base (002) with the pin (005), the plungers (014), and the spring
(006).
3.15 Install these parts in the main bore and torque the screws (001) to 24 Nm.
3.16 Install the non return valves (013) into the related holes and torque them to
8 Nm.
3.17 Install the screw plugs.
3.18 Install the set screw (016) and torque it to 80 Nm.
3.19 Remove the cylinder lubricating pump from the vice.
3.20 Install the solenoid valve (011) and torque the screws to 9 Nm.
4 Do a function test of the cylinder lubricating system, refer to section 12.1.1 Cylinder
lubrication system - do a functional test.
