Chapter 7 - Corrective Maintenance
7.1 Introduction
This chapter provides instructions for adjustments and repairs to the compressor package. Where
special tools are required, they are called out in the applicable paragraph. When installing new O-
rings lightly lubricate them with an O-ring grease such as RIX P/N 45-1007.
DANGER
Before performing any maintenance, the compressor power supply
should be locked
Out of Service
to prevent starting which could cause
injury to personnel or damage to the equipment. Relieve all internal
pressure and allow piping to cool before repair.
7.2 Gas Leak Check
After maintenance or if flow capacity is degraded, all compression end seams should be examined
for leaks. Leak testing requires that the unit be pressurized, and therefore running or recently run.
A soapy solution in a squirt bottle is one method of locating leaks. This test is simplified if the
compressor is allowed to cool, then restarted immediately prior to conducting the leak test; hot
components can boil away the soap solution making detection of leaks difficult or impossible.
Observe for the formation of bubbles. Large leaks may blow the solution away as it is applied, and
therefore must be detected by sound, being careful of hot gases and plumbing. O-ring joints
normally cannot be corrected by additional tightening, in most cases a new O-ring is required.
Always inspect O-ring sealing surfaces for defects. Ensure the proper durometer O-ring is used.
Note
: See A5089 “O-ring Installation & Material Information” in the appendix for more information
about O-rings.
7.3 Cylinder Heads
To remove the cylinder heads, follow the instructions below:
1. Disconnect plumbing from the head.
2. Note the orientation of the head to ensure proper reassembly.
3. Remove the nuts using an alternating cross pattern.
4. Lift the head from the cylinder.
To reinstall the cylinder heads, reference
Figure 1
and follow the instructions below:
1. Install a new O-ring at the top of the cylinder.
2. Correctly orient the head with the cylinder and install.
