1. A hydrostatic axial piston machine, comprising:
a housing;
a drive shaft rotatably mounted in the housing about an axis of rotation, wherein the housing comprises a pot-like housing part having a first abutment and a cover-like housing part having a second abutment, and wherein the two abutments abut each other in a sealing manner;
a first fitting pin inserted precisely into a first fitting recess of the first abutment on the one hand and into a second fitting recess of the second abutment on the other hand; and
a second fitting pin provided on a side opposite the axis of rotation and inserted precisely into a third fitting recess of the first abutment on the one hand and into a fourth fitting recess of the second abutment on the other hand,
wherein the second fitting recess has a radial widening relative to the axis of rotation, and wherein the second fitting recess is a slotted hole and/or a fitting groove.
