FAQ

1. Will this starter motor fit my Doosan DH370-7 excavator from 2008?

Yes, this is a direct OEM replacement for the Doosan DH370-7. It matches the original specifications for the 24V system on the DE12 engine. We recommend visually comparing the mounting flange and pinion gear to your old unit to confirm compatibility.

2. What is the difference between an 11-tooth and a 10-tooth starter?

The number of teeth on the pinion gear must match the flywheel ring gear. The 11-tooth (11T) version is the standard for the Doosan DE12 engine in the DH370-7/HD420-7 models. Using a 10-tooth starter could cause grinding, poor engagement, or damage to the flywheel. Always replace with the same tooth count as your original part (65.26201-7070).

3. How do I troubleshoot if the new starter doesn’t crank?

First, ensure the battery is fully charged and provides a stable 24V. Check all heavy-gauge cable connections (battery, starter solenoid, and ground) for corrosion or looseness. Verify the starter relay and ignition switch are functioning. If the starter clicks but does not turn, the battery may be weak or the starter may be jammed. If it does not engage at all, check the signal wire to the solenoid.
