Click to expand... Is it a stacked valve or a monoblock valve. If the spools do have seals on the shaft, they are there to keep dirt out. On the stacked valves, you can replace the o-rings between the stacks. You can't replace spools as they are a precision fit, and the bore of the valve is probably worn. You can obtain replace valves, that will do the job if they will fit the space allowed.
