27.6 Inspection and testing after
reassembly
27.6.1 Pinion clearance adjustment
1. If the reassembled starter is wired as shown, the
pinion will shift and turn slowly. Remove the
connector from the M terminal to stop the pinion.
2. Under this condition, lightly push in the pinion
toward the armature, and measure the movement
(clearance) of the pinion.
3. To adjust the clearance, increase or decrease the
number of packings fitted to the magnetic switch.
Increasing the number of packings decreases the
pinion clearance.
Unit: mm [in.]
27.6.2 No-Load Test
After adjusting the pinion clearance, hook up the starter
as shown, and test it for no-load characteristics.
