24V 4.5KW 10T Starter Motor PC200-6 for Cummins, Case, Hyundai construction equipment, Liugong

Overview of the PC200-6 Starter Motor

The PC200-6 is a 24V, 4.5 kW starter motor supplied for Cummins, Case, Hyundai construction equipment, Liugong. A reduction gearset between motor and pinion keeps the body compact while still delivering the cranking torque the engine needs.

Because the motor is only used in short bursts, heat builds up quickly and escapes slowly. A starter that has worked for years in traffic or on site will show heat-hardened resin, shortened brushes and a pitted solenoid contact long before the windings fail.

Key Specifications

• Rated voltage: 24V
• Rated output: 4.5 kW
• Pinion: 10 teeth
• Type: reduction gear starter with pre-engaged solenoid
• Application: Cummins, Case, Hyundai construction equipment, Liugong
• Net weight: approximately 8.4 kg
• Condition: new, direct replacement for the original unit

A 24V 4.5 kW rating is the output the motor can hold while cranking, not a peak figure. It is sized so the engine reaches starting speed on the first or second revolution, which is what makes a healthy start feel immediate.

The reduction gearset lets the motor run at high speed while the pinion turns slowly with high torque, which is why the unit stays compact enough for a crowded engine bay.

Reference Numbers and Cross References

Cross references for this starter are listed below. They are a matching aid rather than a substitute for checking the number on the old unit:

• 228000-7902
• PC200-6
• S6D102
• 3934119
• 3957593
• 228000-7900
• 228000-7901

Cross references are a guide, not a fitment guarantee. The same engine family was often built with more than one starter, and the pinion module or terminal bracket can differ between them, so confirm the number on the unit being replaced. This starter is listed with 7 references in total.

Fitment and Application

This starter is used across Cummins, Case, Hyundai construction equipment, Liugong variants that share the same bell housing pattern. Where the original label is missing, the pinion tooth count and terminal position are enough to identify the correct unit. The PC200-6 ships with its solenoid fitted, so no parts have to be transferred from the old unit.

A mismatched pinion is the most common cause of a starter that engages noisily or refuses to mesh. Compare the tooth count before fitting, not after.

Failure Causes

Heat is the underlying cause in most cases. The starter sits close to the exhaust, and after a hot shutdown the solenoid winding and brush plate soak in heat with no airflow. Resin hardens, springs lose tension and the contact oxidises.

Most failures start at the solenoid contact. Each start switches the full cranking current through a copper disc, and after thousands of cycles that disc pits and burns. The result is the familiar single click with no rotation, or a delay before the motor turns. Where a PC200-6 has been replaced before, check that the fitted unit still matches the reference list.

What to Look For

• Click from the solenoid with no rotation, sometimes clearing on a second attempt
• Cranking that has become slower over several weeks
• Grinding as the pinion meets the ring gear
• Starter that keeps running after the key is released
• Intermittent no-crank that appears when the engine bay is hot

Rule out the simple causes first: battery capacity under load, corroded terminals and the signal wire at the solenoid. A starter that clicks with a known-good battery and a clean signal circuit has an internal contact fault. This applies in particular to the PC200-6 supplied for Cummins, Case, Hyundai construction equipment, Liugong.

Pre-Fit Checklist

• State of charge and age of the battery
• Corrosion on the earth strap and the engine-to-body bond
• Pinion tooth count against the ring gear
• Free movement of the new pinion before fitting
• That the signal wire connector seats fully on the solenoid

Fitting a new starter onto a worn ring gear or a marginal battery shortens its life. Check the simple items first, then fit the unit once and correctly.

Fitting Guidance

With the battery isolated, remove any heat shield or ducting that blocks access and disconnect the main cable and solenoid connector. Support the unit before the mounting bolts come out; these starters are heavy enough to damage surrounding parts if they drop.

Clean the mounting face and inspect the ring gear teeth through the starter aperture. Fit the replacement with the original bolts, reconnect the cables in the same order and tighten the main terminal firmly. Crank the engine briefly and listen for clean engagement and release. Because the PC200-6 reuses the original bolts and connectors, no adapters are needed on Cummins, Case, Hyundai construction equipment, Liugong.

Quality Control and Supply from Hejian Nuojin Auto Parts Co., Ltd.

Each production batch is inspected for housing dimensions, terminal integrity and pinion fit, and every starter is bench tested before it is boxed. Units ship in neutral cartons with foam protection, which keeps freight damage low and allows distributors to label stock under their own brand.

Standard references are held as spot goods, volume orders are delivered in around 30 days, and every unit carries a one-year warranty against manufacturing defects.

Frequently Asked Questions

Does this starter come with the solenoid?

The starter is supplied as a complete assembly including the solenoid. Reuse the original mounting bolts if they are in good condition.

How do I confirm the starter matches my vehicle?

Read the number on the starter body or on the old unit and compare it with the reference list above. Where the label is missing, match the pinion teeth and the terminal bracket against the photographs.

Is a 12V and a 24V starter interchangeable?

No. The voltage rating must match the vehicle system; fitting the wrong unit will damage the starter and the wiring.

Can I test the starter on the bench?

Yes. Apply battery voltage to the main stud and the signal terminal and check that the pinion throws and the motor turns. A clamp meter reading against the rated current will show whether the unit is drawing too much.
