Disassembly Procedure

Start By:

1. Remove the control valve (hopper hoist and tow point). Refer to Disassembly and Assembly, "Control Valve (Hopper Hoist and Tow Point) - Remove and Install".

Note: Cleanliness is an important factor. Before assembly, clean all parts thoroughly in cleaning fluid. Allow the parts to air dry. Wiping cloths or rags should not be used to dry parts. Lint may be deposited on the parts which may cause later trouble. Inspect all parts. If any parts are worn or damaged, use new parts for replacement.
