Pinion/Clutch Check

  1. Inspect pinion teeth.
  • Replace pinion if teeth are worn or damaged. (Also check condition of ring gear teeth.)
  1. Inspect planetary gear teeth.
  • Replace planetary gear if teeth are worn or damaged. (Also check condition of armature shaft gear teeth.)
  1. Check to see if pinion locks in one direction and rotates smoothly in the opposite direction.
  • Replace pinion assembly if it is locked or rotated in both directions or unusual resistance is evident.

  • Replace brush holder assembly if the measurement value is less than the specified value.

Brush Check

Brush Spring Check

  • Check brush spring tension with brush spring detached from brush.

Spring tension (with new brush) : Refer to

  • Replace brush holder assembly if the measurement value is less than the specified value.

Brush Spring Check

Brush Holder Check

  1. Perform insulation test between brush holder (positive side) and its base (negative side).
  • Replace brush holder assembly if continuity does not exist.
  1. Check brush to see if it moves smoothly.
  • If sliding surface is dirty, clean it.
  • If brush holder is bent or damaged, replace brush holder assembly.

Armature Check

    3.   Check commutator surface.

  • Clean commutator with No. 500 - 600 emery paper.

Armature Check

    4.   Check diameter of commutator.

  • Replace armature assembly if the measurement value is less than the specified value.

Commutator minimum diameter : Refer to STR

Armature Check

    5.   Check depth of insulating mold from commutator surface.

  • Undercut to 0.5 to 0.8 mm (0.020 to 0.031 in) if the depth is 0.2 mm (0.008 in) or less.

Armature Check

PINION PROTRUSION LENGTH ADJUSTMENT

    1.   Apply battery power to the magnetic switch.

    2.   Push the pinion back to remove the slack and measure clearance "L" between the front edge of the pinion and the pinion stopper.

Clearance "L" : Refer to STR
