ABSTRACT In an hydraulic wobble pump having, a housing assembly which has first and second oppositely disposed outer ends, a wobble chamber and a power transmission chamber formed in said housing, a wobble shaft mounted for rotation in said housing and extending into said wobble and power transmission chambers, said wobble shaft having an inner end located in said wobble chamber, a power transmission gear removably mounted on said wobble shaft and located in said power transmission chamber, a plurality of pistons slid ably mounted in cylinders formed in said housing and extending longitudinally from said wobble chamber to said first outer end of said housing at circumferential spaced intervals about the periphery of a central portion of said housing, the improvement of; a service passage formed at said second end of said housing and opening into said power transmission chamber, said passage being proportioned to permit said power transmission gear to pass there through when being mounted on or removed from the wobble shaft when it is located in said power transmission chamber, a fluid inlet passage extending inwardly from said first outer end through said central portion of said housing and opening into said wobble chamber directly opposite said inner end of said wobble shaft to permit an anvil shaft to extend there through to provide a support which will support the wobble shaft when said power transmission gear is being mounted on wobble shaft when it is located in said housing. The hydraulic wobble pump has an inlet passage extending inwardly from one end thereof through the central portion of said housing and opening into said wobble chamber. The inlet passage being arranged to admit hydraulic fluid to said wobble chamber substantially centrally between said cylinders so as to be substantially uniformly distributed to each cylinder in use.
