The axle oscillation stop further includes a second plate that defines a second through-aperture. The axle oscillation stop includes a dowel pin adapted to removably couple the body portion with a frame of the construction machine. The dowel pin is at least partially receivable within the first aperture. The axle oscillation stop also includes a first fastening device adapted to removably couple the first plate with the frame. The first fastening device is at least partially receivable within the first through-aperture. The axle oscillation stop further includes a second fastening device adapted to removably couple the second plate with the frame. The second fastening device is at least partially receivable within the second through-aperture.

Disclosed are power systems, and power machines employing the power systems, having dual in-line pumps configured to supply hydraulic fluid to respective left and right side travel motors of the power machine. In some exemplary embodiments, pump pintle arm controls and a single centering mechanism for the pintle arm controls are provided. The single centering mechanism is configured to center the pintle arms for each of the two pumps. Also in some exemplary embodiments, a mechanical control linkage configuration allows the separate pump pintle arm controls to be positioned on a side of the pump substantially one behind the other. This allows hydraulic connections to the pumps to be placed on top of the pump assembly, improving the routing of hydraulic hoses in the power machine.
