Caterpillar 1U1818 Control Valve Body Lever Housing Kit

The Caterpillar 1U1818 Control Valve Body Lever Housing Kit is a Caterpillar (CAT) replacement assembly designed to replace the lever housing in the valve-body portion of the hydraulic control system on select CAT bulldozers. Identified by part number 1U1818, this kit is specified for Caterpillar models 173B, 183B, and D7G, indicating compatibility with the valve-body configuration used on those machines. When performing valve-body service, technicians reference 1U1818 to ensure correct fitment with the original Caterpillar hardware for these legacy platforms. The lever housing connects operator input to the valve mechanism, helping translate commands into precise hydraulic movement of the implement and drive circuits. This part is intended for use by technicians carrying out maintenance or rebuild work on older Caterpillar equipment and aligns with the documented valve-body lever-housing configuration for the listed models. The 1U1818 kit provides a precise match to the lever-housing arrangement used in 173B, 183B, and D7G bulldozers, supporting reliable reassembly and continued machine control.
