ABSTRACT:
PCT No. PCT/US 78/00250 Sec. 371 Date Dec. 21, 1978 Sec. 102(e) Date Dec. 21, 1978, PCT Filed Dec. 12, 1978, Ser. No. 014,018, PCT Pub No. W080/01296 PCT Pub. Date Jun. 26, 1980.
A slide rail assembly (18) and slide plate (20) are used, for example, to position an implement (14) of a work vehicle (10), such as a bulldozer (14), at various angles. The bulldozer connected slide plate (20) moves along a vehicle connected rail (22) of the rail assembly (18) to a desired position of the bulldozer (14). A pin (60) is positioned through aligned openings (48,62) in the rail (22) and slide plate (20) to maintain the position. The pin (60) or rail (22) can sometimes fail owing to working loads exerted on the bulldozer (14). A plurality of bushings (50) are each positioned in a respective rail opening (48) and maintained substantially fixed in order to increase bearing support area of the pin (60) and to strengthen the rail assembly (18).
