CONTROL VALVE BODY ASSEMBLE Inspection Procedure

TURBINE SHAFT O-RING INSTALLATION

Fig. 424: Inspecting Control Valve Body For Channel Witness Marks Courtesy of GENERAL MOTORS CORP.

1. Inspect the valve body to spacer plate gasket for valve body channel witness marks. The witness marks should be complete. Incomplete witness marks may be caused by an uneven case surface. Incomplete witness marks may also be caused by cross-channel leaks.

2. Inspect the valve body casting for the following conditions:

• Porosity

• Cracks

• Damaged machined surfaces

• Chips or debris

Cleaning Procedure

1. Clean all the valves, springs, bushings and the control valve body in clean solvent.

2. Dry all the parts using compressed air.
