MAIN LIFT VALVE INSTALLATION
If the sprayer was built prior to model year
2007 then the main lift valve may have to be
replaced with a part from your local Case
Dealership. If the booms will go up, but not
down; the valve will need to be replaced.
The Case part number of the required valve
is 87558232.
1. Lower the main lift all the way to the
bottom.
2. Turn OFF the sprayer ignition.
3. Loosen the hoses on each side of one of
the main lift cylinders located at the
back of the sprayer. This is to remove
any pressure from the system.
4. Remove the coils from the main lift
valve, located under the sprayer.
5. Thread the valve out of the valve
housing and thread the new valve in.
6. Reinstall the coils onto the new main lift
valve.
