ABSTRACT:
A crosshead piston 10 comprises a head member 18 and a skirt member 20, each of which can be secured independently to a piston pin 14. The skirt 20 has a reduced diameter upper end portion 66 which fits within lower end 24 of the head member ring belt portion 23, thereby exposing maximum head member surface area to a cylinder or cylinder sleeve wall for cooling. Preferably, the skirt end portion 66 defines a seal groove 32 which contains a metal ring 67 for sealing the gap 62 between the head member and skirt member.
