The 60081-33111 starter motor is a 24-volt, 9-tooth pinion gear reduction unit engineered for direct mounting on Komatsu 4D95 series diesel engines. It serves as the OEM cranking component for Caterpillar CAT EX120 and Hitachi EX120/EX150 hydraulic excavators equipped with the 4D95 powerplant. The assembly incorporates a high-torque electric motor, solenoid-actuated drive mechanism, and sealed nose housing to withstand construction-site contamination. Electrical terminals conform to JIS heavy-duty truck standards. The unit is a direct replacement for Komatsu part numbers 60081-33111 and 600-813-3111.
