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.

Bearing mounting arrangement for a lift mast

A combined dipstick-breather tube device (13) for use in measuring the level of a body of liquid (L) in a housing (11) wherein turbulence may occur in the liquid making it difficult to make an accurate reading of the level thereof by conventional dipstick devices. The device (13) includes an outer dipstick tube (14) having a vent opening (22) adjacent its upper end above the level of liquid in the housing. The dipstick (18) extends downwardly through the tube (14) and further through a tubular guide (26) which serves as a baffle for preventing impingement of liquid passed inwardly through opening (22) against the dipstick so as to avoid erroneous level readings. The baffle (26) may be defined by a tubular element having integrally formed spacers (28,29) extending outwardly therefrom into engagement with the dipstick tube wall. The upper spacers 28 provide for flow of gaseous fluids between the upper end (23) of the dipstick tube and the opening (22) and the lower spacer (29) provides for a liquid passage (30) to return liquid back to the body thereof in the lower portion of the housing (11) as a result of such liquid passing inwardly through the vent opening 22. The dipstick may be provided with a conventional breather cap (25).
