Starters: Other Kia Sorento I

STARTER CIRCUIT

The starting system includes the battery, starter motor, solenoid switch, ignition switch, inhibitor switch (A/T only), connection wires and battery cables.

When the ignition key is turned to the START position, current flows and energizes the starter motor's solenoid coil. The solenoid plunger and clutch shift lever are activated and the clutch pinion engages the ring gear. The contacts close and the starter motor cranks.

In order to prevent damage caused by excessive rotation of the starter armature when the engine starts, the clutch pinion gear overruns.

PINION GAP

1. With starter on a bench, disconnect the field coil wire from the "M" terminal of the solenoid. (Scheme 8)
2. Connect a 12V battery between "S" terminal and "M" terminal.
3. The pinion will move out.
4. Check the pinion for stopper clearance (pinion gap) with a feeler gauge. See «STARTER SPECIFICATIONS»(ref-164422-S36229433192004080400000) (Scheme 9).
5. If the pinion gap is not within specification, make adjustment by increasing or decreasing number of gaskets between solenoid and front bracket.

CHECKING THE COMMUTATOR

1. Place the armature on a pair of V- blocks and check the runout by using a dial gauge. See «STARTER SPECIFICATIONS»(ref-164422-S36229433192004080400000) .
2. Check the outer diameter of the commutator. See «STARTER SPECIFICATIONS»(ref-164422-S36229433192004080400000) .
3. Check the depth of the undercut between segments. See «STARTER SPECIFICATIONS»(ref-164422-S36229433192004080400000) .
4. Replace commutator if runout, diameter or undercut depth are not within specification.

OVERRUNNING CLUTCH

1. While holding clutch housing, rotate the pinion. Drive pinion should rotate smoothly in one direction, but should not rotate in opposite direction. (Scheme 10) If clutch does not function properly, replace overrunning clutch assembly.
2. Inspect pinion for wear or burrs. If pinion is worn or burred, replace overrunning clutch assembly. If pinion is damaged, also inspect ring gear for wear or burrs.

Cleaning

Overrunning clutch is pre-lubricated at the factory and solvent will wash lubrication from clutch. The drive unit may be cleaned with a brush moistened with cleaning solvent and wiped dry with a cloth.
