Figure 5-54. Solenoid Switch Test Setup.

NOTE

Do not adjust the switch while it is

energized for longer than 30 seconds.

(5) With the switch energized, check the spacing between the face of the pinion and the thrust

washer, using a 0.187-in. thick gage (fig. 5-55). The final adjustment is made by turning the socket clock-

wise or counterclockwise until the 0.187-in, gage just fits between the pinion and the thrust washer.
