b. Slide clutch assembly onto arm ature shaft with pinion
outward.
c. Slide retainer onto shaft with cupped suraface facing
end of shaft (away from pinion).
d. Stand arm ature on end of wood surface with
com m utator down. Position snap ring on upper end of shaft
and hold in place with block of wood. Tap wood block with

pinion will now shift into cranking position and will remain
there until the battery is disconnected.
3. Push the pinion back towards the com m utator end to
eliminate slack movement.
4. M easure the distance between the pinion and pinion
stop (fig. 6D-12S). If clearance is not within specified limits
(.010-. 140) it may indicate excessive wear of solenoid linkage
