62. Q. What are some of the common causes for the compressor stopping?

A. Lack of lubrication; bent, worn or broken reversing rod; loose or

worn reversing plate; nuts on air end of piston rod coming off;

defective compressor governor; and, in addition with the cross-compound

compressor, final discharge valve broken or stuck open, or packing rings

in main valve pistons breaking and catching in the steam ports.
