Positioning a Throw for Maintenance
Compressor maintenance often requires manually turning the crankshaft to locate a particu-
lar throw in one of two positions: the inner dead center or the outer dead center. During nor-
mal operation, the crossheads slide back and forth in the crosshead guides. In the inner
dead center position, the crossheads slide in toward the crankcase as far as possible. In the
outer dead center position, the crossheads slide out away from the crank case as far as pos
-
sible (see figures below). Some procedures, such as setting piston clearances, require a dial
indicator with magnetic base to locate the precise inner or outer dead center.
