BUCKET AR 4726537 - Caterpillar

Left side view of the operator's compartment showing location of the access door (plate assembly).Adaptable To: The new door (plate assembly) is adaptable to earlier tractors. All the tractors need one each of the following parts: 9V2601 Bolt Block, 8T4821 Washer, and 1A0168 Bolt. Additionally, for 621E, 623E, and 627E Tractors, an 8W8102 Plate Assembly is needed. For 631E and 637E Tractors, an 8W7996 Plate Assembly is needed. Each former door (plate assembly) has been canceled and replaced by the new parts and the applicable new door (plate assembly).
Install the new door and the bolt (with washer) through the hole in the spacer in the door. With the plate snugly in place, weld the new block to the operator's compartment so the new bolt will thread straight into the block and hold the door tightly on the tractor.
