COMPRESSOR BLOCK ASSEMBLY
The compressor block assembly work sequence plan (Figure 6-54) is provided to serve as a guide in assembling
the compressor block. With this plan the work sequence for each step of assembly can be clearly seen. The
individual assembly groups are illustrated in the work sequence plan by fields.

a.
Instructions for Use of the Work Sequence Plan
(1)
See work sequence plan.
(2)
Locate all assembly groups to be assembled or replaced in the work sequence plan.
(3)
Trace all connecting lines leading from each assembly group to be assembled or replaced to the starting
point. All affected assembly groups must be assembled before the assembly group selected can be
assembled.
(4)
Assemble groups closer to the starting point before groups further displaced from the starting point,
following the connecting lines to the right.
(5)
If several connecting lines from the left converge on one assembly group field, all assembly groups on
these lines must be previously assembled.
b.
Example (see Figure 6-54). The assembly group A23, valve head 4th stage, is to be assembled. The
following assembly groups must be assembled first: A22 bearing cover, A32 connecting rod 3rd stage,
A31 connecting rod 4th stage, A30 connecting rod 1st stage, A29 connecting rod 2nd stage, A28
counterweight, A41 upper part of crankcase, A27 driving gear, A26 guide piston 4th stage, A25 cylinder
4th stage, A24 floating piston with piston sleeve 4th stage, A21 discharge valve 4th stage, A20 inlet
valve 4th stage.
