ABSTRACT OF THE DISCLOSURE An axial piston fluid placement device includes a cylinder barrel journaled in a housing with a plurality of cylinders each having a piston. Each piston pivotally mounts a shoe that slides over a front face of a swashblock which has a pair of rear arcuate bearing surfaces supported in the housing. A pair of arcuate bearings are disposed against the housing support and are engaged by the swash- block bearing surfaces. The pistons and shoes have cooper- ating passages that lead from a cylinder to the front face of the swashblock to provide fluid from the cylinders to lubricate the front face of the swashblock. An opening is provided in the front face of the swashblock in the path of the shoes and axially aligned with the bearing surface that is opposite the high pressure port. A passageway is formed internal of the swashblock and leads from the open- ing to the groove. A small controlled amount of fluid from the passages in the pistons and shoes will be pumped into the opening and through the passageway to deposit fluid in the groove to lubricate the bearing.
