5.5 Disassembly Sequence
Generally compressors are disassembled in the order shown in Figure 5-1 Illustrated
Disassembly Sequence but the order in the figure is just an example and the actual order may
differ according to individual situations.
For instance when overhauling it is no problem to start separation of high-stage part from
low-stage part after removing the compressor from the unit frame and putting it on the work bench
prepared beforehand.
In addition it is often the case that the disassembly of unloader cover/unloader cylinder part from
mechanical seal part is performed in the reverse order of shown in the Figure 5-1.
Shown in the steps in the Figure 5-1, ① through ⑤ ,⑩ and ⑪, you can disassemble the
compressor with the compressor attached on its frame.
When conducting steps ⑦ through ⑳, perform each step after removing the compressor and
placing it on the work bench.
When conducting steps ⑦ through ⑳, the compressor should be removed from its frame and placed
on a work bench prepared in advance.
When disassembling high-stage or low-stage side only, start from step ⑦ and disassemble necessary
parts only.
Parts which have no problem should be left as they are. Do not disassemble such parts unless during
periodical inspection.
Since it is difficult to completely eliminate the risks of performing inaccurate work at the field,
disassemble the minimum required parts only.
