7.4.3Reassembly of the Defogger Valve

Tools Required:

3/8 inch Slotted Flat Blade Screwdriver

13/16” Open End Attachment on Torque Wrench Minimum recommended replacement parts during overhaul:

Washers, O-rings

1)Screw in the new seat assembly until it is even with the front of the side block body.

2)Next, install the Teflon® washer and O-ring onto the stem.

3)Insert the proper end of the stem into the seat assembly and turn clockwise until the seat lightly bottoms out. Leave the stem in place.

4)Lubricate the O-ring and install on the bonnet.

5)Slide the bonnet over the stem and thread the bon-

net into the side block.

6)Tighten the bonnet with a torque wrench to 100 inch lbs.

7)Place the new Teflon® washer and the control knob on the stem and rotate the stem counterclockwise until the seat assembly tops out fully open. The control knob must turn smoothly without any binding.

Binding (or “hard spots”) in the rotation could be an indication of a bent stem that should be replaced. Replace the knob and or stem if the fit allows the valve to rotate loosely more than 1/8th of a turn.

8)Install the new Teflon® washer, new knob, and the spring, and locknut. Tighten the locknut until it is flush with the knob.
