Cummins 6BT5.9-GM83 diesel engine starter motor 5403868

The starter motor is a heavy-duty electric motor powered by the battery. It turns over the engine when you want to start it. If a diesel engine doesn’t start, does it mean that the starter motor is bad? Not always, a bad starter motor is only one of the possible causes; read how the starting system works below.

What are the signs that the starter motor is going bad ? Sometimes a starter motor just stops working one day with no prior signs. In some cases, when the starter motor is going bad, you may notice that the engine won’t turn over on the first attempt; it may take several tries before the starter motor engages. Sometimes a worn-out or shorted starter may turn over slower than usual, even if the battery is fully charged or new. In some diesel engines, a starter motor may produce abnormal grinding or screeching noises when it’s going bad. Another sign is when at times a starter motor won’t crank the engine when hot, but works fine when it’s cold.

Anyway, if your Cummins 6BT5.9-GM83 engine starter indeed is dead, you can buy this starter from China, from our company — Yangzhou Yongcai Machinery Co., Ltd.

What is starter motor ?

Wikipedia tells us : A starter (also self-starter, cranking motor, or starter motor) is a device used to rotate (crank) an internal-combustion engine so as to initiate the engine’s operation under its own power. Starters can be electric, pneumatic, or hydraulic. In the case of very large engines, the starter can even be another internal-combustion engine.

Internal combustion engines are feedback systems, which, once started, rely on the inertia from each cycle to initiate the next cycle. In a four-stroke engine, the third stroke releases energy from the fuel, powering the fourth (exhaust) stroke and also the first two (intake, compression) strokes of the next cycle, as well as powering the engine’s external load. To start the first cycle at the beginning of any particular session, the first two strokes must be powered in some other way than from the engine itself. The starter motor is used for this purpose and it is not required once the engine starts running and its feedback loop becomes self-sustaining.
