Replacing the valve plates
The compressors are divided into an LP and an HP compressor stage. Different valve
plate designs are required because of the different ducts in the individual compressor
stages.
The valve plates have been fitted with safety bolts to prevent any confusion.
The safety bolts engage in the corresponding bores on the cylinder heads, the safety
bolts must not be removed!
