(5)Pinion clearance adjustment
The pinion clearance must be 0.020 to 0.079
in. (0.5 to 2.0mm). With the pinion held in
cranking position, lightly push it toward
commutator end to measure free movement
(clearance). If the clearance is not correct,
make adjustment to it. Increase the amount of
packings if the clearance is too large; decrease
it if the clearance is too small.
