24V 4.5KW 10T Starter Motor PC200-6 for 16, 1000 实时翻译 16, 1000 Real time Translation Excavator

Overview of the PC200-6 Starter Motor

The PC200-6 is a 24V, 4.5 kW starter motor supplied for 16, 1000 实时翻译 16, 1000 Real time Translation Excavator. A reduction gearset between motor and pinion keeps the body compact while still delivering the cranking torque the engine needs.

Every unit is bench tested at the factory for current draw, solenoid pull-in and pinion throw, because those three values decide whether a starter works in a cold engine bay as well as it does on a test bench.

Specification Summary

• Rated voltage: 24V
• Rated output: 4.5 kW
• Pinion: 10 teeth
• Type: reduction gear starter with pre-engaged solenoid
• Application: 16, 1000 实时翻译 16, 1000 Real time Translation Excavator
• Net weight: approximately 8.25 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 drive end housing is cast aluminium and carries the pinion bearing, so the pinion stays square to the ring gear when the motor delivers full torque.

Reference Numbers and Cross References

The starter is supplied against the following references, which help identify it against the unit already fitted to the vehicle:

• 6D102
• 228000-0630
• 228000-0631
• 600-863-4210
• PC200-6
• S4D102

Where the label on the old starter has corroded, compare the pinion teeth, the mounting flange and the terminal bracket with the photographs before ordering. The number on the original unit is the reliable identifier. This starter is listed with 16 references in total.

Fitment and Application

This starter family was fitted to a range of the manufacturer applications, and the part number changed as engines and flywheels were revised. The unit listed here covers the references above and is a direct replacement where those numbers match. Owners of 16, 1000 实时翻译 16, 1000 Real time Translation Excavator should treat the PC200-6 reference list as a starting point, not the final answer.

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.

Oil or coolant mist from a leaking seal finds its way into the drive end housing, mixes with carbon dust and forms a conductive paste. The starter then arcs internally and fails early, whatever its mileage. This applies in particular to the PC200-6 supplied for 16, 1000 实时翻译 16, 1000 Real time Translation Excavator.

Diagnostic Signs

• Cranking that sounds normal but takes longer than it used to
• Several attempts needed before the motor engages
• Black carbon dust inside the drive end housing
• Voltage dip that dims the lights during cranking
• Starter that responds to a tap on the housing but not to the key alone

A cranking voltage test separates the starter from the rest of the circuit. If battery voltage stays healthy at the terminals but drops sharply at the starter stud, the cable or the connection is at fault rather than the motor. The PC200-6 is built to the same flange pattern as the unit it replaces.

Before You Fit the Replacement

• Battery capacity under load, not just open-circuit voltage
• Terminal clamps and the main cable lug for corrosion or heat marks
• Earth strap between engine and chassis
• Ring gear teeth, visible through the starter aperture
• Key switch and signal wire voltage at the solenoid terminal

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.

Installation Procedure

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.

Check the ring gear through the aperture before fitting. Install the new unit with the original bolts, reconnect the cables in the same order and tighten the main terminal without over-stressing the stud. Crank briefly and confirm the pinion releases as the engine fires. The PC200-6 ships with its solenoid fitted, so no parts have to be transferred from the old unit.

Frequently Asked Questions

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.

Why does the starter work cold but fail when hot?

Heat raises solenoid resistance and reduces brush spring pressure. Both effects build up gradually and appear first on a hot restart.

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.

Does this starter come with the solenoid?

Yes. The unit is supplied complete with its solenoid, as shown in the product photographs. Mounting bolts are not included.
