Product Information and Technical References

Cross Reference and Number Format

The main part number for this page is 65.26201-7074B. The non-dot and non-hyphen format 65262017074B may also appear in catalog searches, supplier listings and buyer inquiries.

Common related starter references include 65.26201-7074, 65.26201-7074A, 65.26201-7074C, 65.26201-7074D, 300516-00075 and 080723KA. These numbers should be treated as cross reference support, not as automatic interchange confirmation.

Starter motors in the same reference group may still have different power rating, mounting ear shape, pinion offset, solenoid position, drive gear engagement or terminal layout. For this reason, the old starter nameplate and physical structure should be checked before quotation.

Daewoo DE12TIS Engine Application Notes

The 65.26201-7074B starter motor is commonly referenced for Daewoo DE12TIS engine starting system service. It is suitable for buyers who need to replace a failed starter after no-crank failure, slow cranking, solenoid clicking, abnormal gear noise or starter overheating.

Engine model is useful for initial identification, but it should not be used alone. Different machines using similar Daewoo or Doosan engine families may use different starter specifications, so the old starter label, machine serial number and unit photos should be compared before ordering.

Doosan Daewoo Model References

This starter motor is often searched for Doosan Daewoo excavator and wheel loader repair. Common model references include Solar 340LC-V, Solar 400LC-III, Solar 420LC-V, Solar 470LC-V, Solar 500LC-V, DX420, MEGA 300-V and MEGA 400-V.

These model names are useful for search and initial identification, but they should be treated as model references rather than guaranteed applications. Before ordering, confirm the old starter number, engine model, voltage, gear teeth, mounting holes and wiring layout.

Technical Identification Points

• Confirm the old starter label shows 65.26201-7074B or a matching reference number.

• Check whether the machine uses a 24V starting system.

• Compare the power rating on the old starter label because catalog references may vary.

• Verify the 11-tooth drive gear and pinion engagement position.

• Compare CW rotation with the removed starter unit.

• Check mounting holes, solenoid position and terminal layout before installation.

Common Failure Symptoms

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

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

• The engine cranks slowly even when the battery is charged.

• Grinding noise appears during starting because the pinion does not engage correctly.

• The pinion gear does not return smoothly after the engine starts.

• The starter overheats after repeated cranking attempts.

• Burning smell or visible damage appears around the starter motor or cable terminal.

Troubleshooting Before Replacement

Before replacing the 65.26201-7074B starter motor, inspect the complete starting circuit. Battery failure, poor grounding, loose cables, relay problems or engine hard-start conditions can create symptoms similar to starter failure.

• Check battery voltage and battery load capacity.

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

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

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

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

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

Installation and Maintenance Notes

• Disconnect the battery before removing the starter motor.

• Clean the mounting surface before installation.

• 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 and damage the solenoid.
