Abstract: A dump vehicle comprising a chassis and a dump bed with a cylinder laterally constrained by a stabilizer. The cylinder is supported on a support structure and pivotably connected thereto and to the dump bed. The stabilizer includes a retainer extending at least partially around the cylinder and having arms extending downwardly from the retainer and outwardly from the cylinder. The stabilizer constrains the cylinder laterally, at least partially absorbing side loads imposed on the cylinder.

Abstract: An improved self-lubricating bearing arrangement for gear pumps utilizes a system of material feed channels and reservoir pockets to divert a portion of the material being pumped from the pressure side of the intermeshing gears to lubricate the gear-supporting shafts within the bearing arrangement. At each gear shaft, a linear material feed channel is formed in the radial face of the bearing between a pressure relief recess and an axial opening supporting the shaft and a parabolic reservoir pocket is formed within the bearing opening adjacent the shaft to apply diverted polymer to the shaft. Each material feed channel and reservoir pocket is polished to a mirror finish to minimize any tendency of suspended additives in the polymer from adhering to or collecting within the channels or pockets, thereby to prevent unusual or localized wearing of the gear shafts.
