personnel, remove compressor from frame.

17.Remove shims and spherical washers from com- pressor mounting locations.

18.Inspect shims and spherical washers for damage, replace as required.

INSTALLATION

19.Install shims and spherical washers on compressor mounting locations, see Figure 5-10.

20.Install appropriate lifting eyes on top of compressor.

21.Using appropriate lifting device, position compres- sor on compressor mounting locations on frame.

22.Loosely install studs, lock washers, ﬂat washers and nuts to secure compressor to frame until alignment is correct.

23.Check compressor for soft foot. Add or remove shims as required until measurements are within +/- 0.002”.

24.Tighten nuts to secure compressor to frame, refer to Appendix A.

25.If equipped with C-ﬂange, install bolts to se- cure C-ﬂange to compressor. Tighten bolts, see Appendix A.

26.If equipped with C-ﬂange, install C-ﬂange coupling, refer to C-ﬂange Coupling Replacement procedure.

27.Install coupling, see Drive Coupling Installation and Alignment procedure .

28.Install coupling guard.

29.Install nuts and bolts to secure discharge pipe to oil separator and compressor.

30.Tighten nuts on ‘discharge pipe-to-compressor ﬂange’ ﬁrst, then tighten nuts on ‘discharge pipe- to-oil separator ﬂange’, see Appendix A.

31.Install nuts to secure suction strainer/check valve assembly to compressor and suction stop valve.

32.Tighten nuts on ‘suction strainer/check valve as- sembly-to-compressor’ ﬁrst, then tighten nuts on ‘suction strainer/check valve assembly-to-suction stop valve’, refer to Appendix A.

33.Install all lines to compressor.

34.Install all cables to sensors on compressor and actuator.

35.Perform leak check, see Compressor Unit Leak Check procedure.
