980G Wheel Loader Hydraulic System Caterpillar


Pilot Valve (Oil Manifold)

Usage:

980G 2KR

114-2803 Pilot Valve (Oil Manifold)

Note: The pilot valve (oil manifold) in illustration 1 is for machines with an auxiliary function (logging fork, side dump bucket, multipurpose bucket, etc). Machines without an auxiliary attachment will not have attached valve body (4). 113-0282 Pilot Valve will be the designation for the valve.
