8.4 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.
