9.11 Maintenance activities - Intake valves and pressure valves
9.11.1 Servicing the suction valves and pressure valves
While servicing the valves, be mindful of the following action steps:
1.
Clean contaminated suction and pressure valves. Do not use any sharp tools.
Instead, soak the valves with diesel oil or petroleum and clean them with a
soft brush.
2.
Check the individual parts for excessive wear. If the valve seats and valve
plates are showing indentations, replace the valves, see
Chapter 9.11.2 Re-
placing the suction valves and pressure valves, Page 111.
3.
Check the valve chamber in the valve heads for contamination and clean if re-
quired.
4.
During reassembly, follow the correct sequence.
5.
Check the seals and O-rings for perfect condition when re-assembling, and re-
place them if necessary.
6.
Use a torque wrench to tighten the valve head screws, see Chapter 9.3.1 Bolt
torques, Page 84.
7.
After all the maintenance work has been completed, turn the compressor over
by hand at the flywheel in order to determine that all parts have been fitted
correctly.
8.
Start up the unit.
9.
30 minutes after re-starting, switch the unit off and allow it to cool down.
10.
Re-tighten the valve head screws with the specified torque, see Chapter 9.3.1
Bolt torques, Page 84. The settling of the seals can otherwise lead to loosen-
ing of the valves.
9.11.2 Replacing the suction valves and pressure valves
Only competent personnel may replace the valves of the compressor. For more in-
formation, contact the BAUER customer service department, see Chapter 1.1.1
