to the starting motor as shown in Figure 49. This
will allow the pinion of the starting motor to slide

when the pinion is pushed lightly toward the
commutator end. Clearance should be .02" to
.06". Adjust for proper clearance by removing the
magnetic switch attaching screws and select
proper thickness of the fiber packings shown in
Figure 50.
