7. Inspection and adjustment of starter pinion
1) Inspection and adjustment of the clearance between pinion and retaining ring
Turn on the electromagnetic switch circuit to make the iron core be sucked fully. At this time when the starter
pinion moves to the farthest position, check that whether there is a clearance of 0.5-3 mm between the end
face of the pinion and the retaining ring. If not, adjustment shall be made. Gaskets can be placed at the
bottom of the starter’s electromagnetic switch to ensure good pinion engagement.
2) Inspection and adjustment of pinion’s installation position
During installation of the starter, clearance of 3-5 mm shall be kept between the pinion end face and the
flywheel gear ring end face. Otherwise, add or remove gaskets between the stop plane of the starter and the
flywheel housing of the engine to ensure reliable meshing of the pinion.
