Doosan 300516-00120 Starter Motor Assembly

The 300516-00120 is a 12-volt, 2.7-kilowatt electric starter motor featuring an 11-tooth pinion gear. It is engineered as a direct OEM replacement for Doosan (Develon) excavator applications, specifically the Solar 50W-III mini excavator series. The unit utilizes a gear-reduction drive mechanism to deliver high cranking torque for reliable cold-weather starting of Doosan D24 and DL06 series diesel engines. Constructed with a heavy-duty solenoid and corrosion-resistant housing, the starter meets OE specifications for mounting flange geometry and electrical connector interface. It supersedes earlier part numbers including 300516-00034A and cross-references Delco Remy 8200475 series units. Designed for severe-duty construction machinery cycles, the armature and field coils are wound for sustained thermal performance under repeated engagement.
