摘要： A lubricant retainer for use in a pump bearing assembly, the bearing assembly which in a first operating configuration is lubricated by a relatively highly viscous lubricant, and which in a second operating configuration is lubricated by a less-viscous lubricant, the bearing assembly comprising a bearing housing having a bore extending therethrough for receiving a pump drive shaft, spaced-apart bearing mounting zones within said bore with a chamber therebetween, each bearing mounting zone arranged for the in use receipt of a bearing therein. Each zone has associated therewith one lubricant retainer, the lubricant retainer being adapted to be mounted within the bore adjacent the bearing mounting zone with which it is associated so as to form a barrier between the bearing mounting zone and the chamber when the pump bearing assembly is in the first operating configuration, the retainer being removed when the pump bearing assembly is in the second operating configuration.

摘要： A coupling pin for use in a pump housing, the pump housing including an outer casing and an inner pump liner, the coupling pin being suitable for locating the liner and casing relative to one another, the coupling pin including a shank and a head at one end of the shank. The head includes a cammed surface thereon which is adapted to co-operate with a follower on the liner, and a locating section on a remote or terminal end of the head which is adapted to be positioned against a seat in the outer casing when fitted. The arrangement is such that rotation of the coupling pin causes the follower to track along the cammed surface so as to cause relative movement between the outer casing and the inner pump liner.
