Claim:
A centering mechanism for a hydraulic pump, the pump including a pump housing and an input shaft extending along an axis, the pump having a neutral condition in which hydraulic fluid does not flow through the pump, a control arm being connected to the shaft, movement of the control arm controlling operation of the pump, the centering mechanism comprising: a bracket assembly including a first bracket fixable to the housing and defining threaded holes, a second bracket adjustably fixable to the first bracket member, the second bracket defining slots associated and partially alignable with the threaded holes, and adjusting fasteners, each adjusting fastener extending through an associated slot and threadable in an associated threaded hole to adjustably fix the second bracket to the first bracket; and biasing structure operable to return the control arm to a centered position when an operating force is not applied to the control arm; wherein the second bracket is adjustable relative to the first bracket such that the centered position corresponds to the neutral condition of the pump, the second bracket being fixable in the position by the adjusting fasteners.
