An axial piston pump assembly including a housing having first and second portions with the second portion being cup-shaped and closed by the first portion which defines a closure or cover. A cylinder barrel is rotatably supported in the housing and includes a plurality of piston cavities in which a plurality of pistons are reciprocatively supported. A cam reacts with the pistons for causing reciprocating movement of the pistons as the cylinder barrel is rotated about an axis of rotation. A spicket shaft extends from the cover portion of the housing and into a cavity in the cylindrical barrel. The spicket shaft has a thrust bearing supported at the distal end thereof. Pins are press-fitted into the cylindrical barrel to engage the thrust bearing whereby reaction forces resulting from reciprocating movement of the pistons by the cam are transmitted through the cylindrical barrel, the pins and the thrust bearing to the spicket shaft and, thus, to the cover or first portion of the housing whereby the cup-shaped portion of the housing is free of tensile loads. |
