Repair

Disassembly, inspection and reassembly steps are the same as the steps in the previous topic (Electric
Controls). This includes repair of the spools and plugs.
The solenoid (C155), nut (QC125), and O-rings (QC120) for the valve are available as separate repair
parts. The valve is only available as a complete assembly (QC150).
If it is necessary to remove the orifice (H020), use a 3 mm internal hex wrench. Torque it to 2.7 Nm [24
in-lb] when it is installed in the manifold.
