Hyundai Kona (OS) 2018-2024 Service Manual / Engine Electrical System / Starting System / Starter Repair procedures

Removal

1.	Disconnect the battery negative terminal.

2.	Remove the under cover. (Refer to Engine Mechanical System - "Engine Room Under Cover")

3.	Remove the vacuum pump. (Refer to Brake System - "Vacuum Pump")

Disconnect the starter cable (B) from the B terminal on the solenoid, then disconnect the connector (A) from the S terminal.

Starter "B" terminal tightening nut :

9.8 - 11.8 N.m (1.0 - 1.2 kgf.m, 7.2 - 8.7 Ib.ft)

Remove the starter (A).

Starter mounting bolt :

49.0 - 63.7 N.m (5.0 - 6.5 kgf.m, 36.2 - 47.0 lb.ft)

6.	Remove the starter.

Installation

1.	Install in the reverse order of removal.

Disassembly

1.	Disconnect the M-terminal (A) on the magnet switchassembly.

2.	After loosening the 2 screws (A), detach the magnet switch assembly (B).

3.	Loosen the brush holder mounting screws (A) and the trough bolts (B).

4.	Remove the rear bracket assembly (A) and brush holder assembly (B).

5.	Remove the yoke assembly (A).

Remove the packing (A), lever plate (B), lever (C), armature assembly (D).

•	Beware the direction of lever (A).

7.	Press the stopper (A) using a socket (B).

8.	After removing the stop ring (A) using stopper pliers (B).

Remove the stop ring (B), stopper (A), overrunningclutch (C) and armature (D).

•	Using a suitable pulling tool (A), pull the overrunningclutch stopper (C) over the stop ring (B).

Reassembly

1.	Reassemble in the reverse order of disassembly.

Inspection

Armature

1.	Remove the starter.

2.	Disassemble the starter as shown at the beginning of this procedure.

3.	Inspect the armature for wear or damage from contact with the permanent magnet. If there is wear or damage, replace the armature.

4.	Check the commutator (A) surface. If the surface is dirty or burnt, resurface with emery cloth or a lathe within the following specifications, or recondition with #500 or #600 sandpaper (B).

Check the commutator diameter. If the diameter is below the service limit, replace the armature.

Commutator diameter

Standard (New) : 29.4 mm (1.1575 in)

Service limit : 28.8 mm (1.1339 in)

Measure the commutator (A) runout.

•	If the commutator runout is within the service limit, check the commutator for carbon dust or brass chips between the segments.

•	If the commutator run out is not within the service limit, replace the armature.

Commutator runout

Standard (New) : 0.05 mm (0.0020 in.) max

Service limit : 0.10 mm (0.0039 in.) max

Check the mica depth (A). If the mica is too high (B), undercut the mica with a hacksaw blade to the proper depth. Cut away all the mica (C) between the commutator segments. The undercut should not be too shallow, too narrow, or v-shaped (D).

Commutator mica depth

Standard (New) : 0.5 mm (0.0197 in.)

Limit : 0.2 mm (0.0079 in.)

8.	Check for continuity between the segments of the commutator. If an open circuit exists between any segments, replace the armature.

9.	Check with an ohmmeter that no continuity exists between the commutator (A) and armature coil core (B), and between the commutator and armature shaft (C). If continuity exists, replace the armature.

Starter Brush

Brushes that are worm out, or oil-soaked, should be replaced.

Bruch length

Standard : 12.3 mm (0.4843 in)

Service linit : 5.5 mm (0.2165 in)

•	To seat new brushes, slip a strip of #500 or #600 sandpaper, with the grit side up, between the commutator and each brush, and smoothly rotate the armature. The contact surface of the brushes will be sanded to the same contour as the commutator.

Starter Brush Holder

1.	Check that there is no continuity between the (+) brush holder (A) and (-) plate (B). If there is continuity, replace the brush holder assembly.

Overrunning Clutch

1.	Slide the overrunning clutch along the shaft. Replace it if does not slide smoothly.

2.	Rotate the overrunning clutch both ways. Does it lock in one direction and rotate smoothly in reverse? If it does not lock in either direction of it locks in both directions, replace it.

3.	If the starter drive gear is worn or damaged, replace the overrunning clutch assembly. (the gear is not available separately) Check the condition of the flywheel or torque converter ring gear if the starter drive gear teeth are damaged.

Cleaning

1.	Do not immerse parts in cleaning solvent. Immersing the yoke assembly and/or armature will damage the insulation wipe these parts with a cloth only.

2.	Do not immerse the drive unit in cleaning solvent. The overrun clutch is pre-lubricated at the factory and sol-vent will wash lubrication from the clutch.

3.	The drive unit may be cleaned with a brush moistened with cleaning solvent and wiped dry with a cloth.
