Abstract:
1. A coupling pin for use in a pump housing having an outer casing and an inner pump liner to engage the inner pump liner with the outer casing, the coupling pin having a shank and a head positioned at one end of the shank, the head having a cammed surface structured to engage a surface of a pump liner adapted to receive said cammed surface in registration therewith, and a locating section at a terminal end of the head which is structured with a profile adapted to be recieved against an outer casing of a pump, the arrangement being such that rotation of the coupling pin causes the surface of a pump liner to track along the cammed surface of the head of the coupling pin so as to cause relative movement between an outer casing and an inner pump liner of a pump.
