This Special Instruction outlines the basic procedures in order to relocate the bumper assemblies on the support assembly for the pilot control valves. If the 180-7244 Plate As becomes clogged with dirt or debris, the bumper assemblies will bottom out before the support assembly can be latched into the desired position. The bumper assemblies can be relocated in order to provide sufficient latching of the support assembly. The bumper assemblies are now located on the 220-3688 Plate As. The 220-3688 Plate As replaces the 180-7244 Plate As .The Special Instruction is available through the normal literature distribution system. The publication can also be found on the Caterpillar Service Information System (SIS).
