600-863-5111 24V Starter Motor for Komatsu 6D107 Engine

600-863-5111 Starter Motor for Komatsu 6D107 Engine

The 600-863-5111 starter motor is used for Komatsu diesel engine starting system service and is commonly searched together with the non-hyphen format 6008635111. This page focuses on the 24V 10T starter motor application for Komatsu 6D107 engine references, with Komatsu PC200-8, PC210-8 and PC220-8 excavator model references included for fitment checking.

Public aftermarket references commonly list this starter with 24V voltage, 10 drive teeth, clockwise rotation and 5.5kW power reference. Because starter motors may vary by engine version, machine serial number, mounting layout and previous repair history, final fitment should be verified by the old starter label, teeth count, rotation direction, mounting holes, pinion position and terminal layout before ordering.

Product Information

Cross Reference and Number Format

The main part number for this page is 600-863-5111. The format 6008635111 is the non-hyphen writing format and is often used in aftermarket searches, catalog listings and buyer inquiries.

Common reference numbers connected with this starter include 600-863-5110, 6738-82-6810 and 6736-81-4210. Some supplier catalogs may also mention 600-863-5115, 6742-81-4210, Denso 228000-5000, 228000-5001, 228000-5003 and DSN2001 type references.

These cross reference numbers should be used as identification support, not as automatic interchange confirmation. A similar starter motor may still have a different mounting ear position, pinion offset, solenoid direction, terminal layout or gear engagement depth.

Komatsu 6D107 Engine Application Notes

The 600-863-5111 starter motor is mainly positioned for Komatsu 6D107 engine starting system repair. It is commonly searched for Komatsu excavators such as PC200-8, PC210-8 and PC220-8, especially when buyers identify the machine by excavator model instead of starter nameplate.

Some aftermarket listings also mention 6D102E or S6D102E together with 600-863-5111. These should be treated as supplier reference information only. For accurate replacement, confirm the original starter label and compare the unit structure before ordering.

Komatsu Excavator Model References

This starter is often searched for Komatsu PC200-8, PC210-8, PC220-8, PC220LC-8M0 and PC240LC-8 excavator repair. These model references are useful for search and initial identification, but they should not replace serial number and old part number confirmation.

If the excavator has been repaired before, the installed starter may not match the original catalog configuration. Before ordering, check the old starter nameplate, engine model, voltage, teeth count, mounting holes, pinion position and connector layout.

Technical Identification Points

• Confirm the voltage is 24V before replacement.

• Check whether the starter drive gear has 10 teeth.

• Compare clockwise rotation with the old starter unit.

• Inspect the mounting ear layout and bolt hole position.

• Check the pinion offset and gear engagement position.

• Compare the solenoid position and terminal layout with the removed starter.

Common Failure Symptoms

• The engine does not crank when the start switch is turned on.

• The starter solenoid clicks, but the motor does not rotate.

• The starter turns slowly even when the battery is charged.

• Abnormal grinding noise appears during starting.

• The starter pinion does not engage with the flywheel correctly.

• The starter remains engaged or does not return smoothly after engine start.

• The starter overheats after repeated cranking attempts.

Troubleshooting Before Replacement

Before replacing the 600-863-5111 starter motor, inspect the complete starting circuit. A weak battery, poor grounding, damaged starter cable, relay failure or engine hard-start problem can create symptoms similar to starter motor failure.

• Check battery voltage and load capacity.

• Inspect battery terminals, ground cable and main starter cable for corrosion or looseness.

• Check starter relay, start switch signal and solenoid control wire.

• Confirm the engine is not mechanically locked or difficult to rotate.

• Inspect the flywheel ring gear if grinding noise appears during cranking.

• Compare the old starter voltage, teeth count, rotation and mounting layout with the replacement unit.

Installation and Maintenance Notes

• Disconnect the battery before removing the starter motor.

• Clean the mounting surface before installing the replacement starter.

• Make sure the starter sits flat against the engine housing.

• Tighten mounting bolts according to the service requirement and avoid misalignment.

• Check the main power cable and control terminal before reconnecting the battery.

• After installation, test starting performance and listen for abnormal gear engagement noise.

• Avoid repeated long cranking because it can overheat the starter motor and damage the solenoid.
