New aftermarket Iskra/Hitachi-pattern starter for Cummins MerCruiser Diesel D1.7L DTI and CMD 1.7 MI/MS engines.

🔌 Function

The gear-reduction starter multiplies motor torque to crank the high-compression diesel engine. The solenoid engages the 13-tooth drive with the flywheel and closes the high-current circuit.

Common signs of failure:

• Solenoid clicks without engine rotation

• Slow cranking, especially when the engine is warm

• Pinion spins without engagement or repeatedly kicks out

• Grinding caused by an incorrect 9-tooth or 13-tooth substitution

• High current draw, overheated cables or burnt solenoid contacts

• Internal corrosion, worn brushes or damaged reduction gears

📦 Condition

• Brand-new aftermarket replacement starter motor

• New and unused

• Supplied in suitable manufacturer or equivalent protective packaging
