justable; however, some clearance must
be maintained between end of pinion
and starter drive frame to assure solid
contact of the magnetic switch. Normal
pinion clearance should be within the
limits of 0.25-3.56 mm (0.010-0.140
inch). Connect a
solenoid terminals when measuring pin·
ion clearance to keep armature from
