ABSTRACT:
A bearing mounting arrangement for a lift mast assembly has a retaining device which maintains a bearing member from movement relative to a first member of a lift mast assembly and directs a flow of lubricant past a second surface of the bearing member and into a groove opening at a first surface in the bearing member. The retaining device includes an elongated retaining member disposed in an aperture in the bearing member and the first member. The retaining device forcibly engages the bearing member and aligns the apertures in the bearing and first members. The bearing mounting arrangement is particularly useful for mounting a lift mast assembly on a material handling vehicle and a thrust bearing member on a side shaft carriage.
