5.3.6 Crosshead and guide shoe
The crosshead guides the piston rod (009, Figure 5-18 ) and absorbs the lateral forces that come
from the connecting rod (005).
The piston rod (009) is attached to the compression shim (007) and the crosshead pin (006) with
screws. The bearing oil necessary to keep the piston cool, flows through the space (002) to the
piston. The oil from the piston flows back through the oil pipe (001) to the crosshead pin (006).
Then the oil flows into the crankcase.
The guide shoes (004) are attached to the crosshead pin (006) and move up and down on the
guide ways of the column. The guide rails (008) hold the guide shoes (004) and thus the crosshead
in the horizontal position.
