Product Overview

The ME701492 starter armature (OE ME701492, 618335, IM3095) is a new, OE-spec replacement rotor built for Mitsubishi starter motors, including the 4D33 engine application. Rated at 24V 3.7KW with a 13-segment commutator, this armature restores reliable cranking torque so your Mitsubishi engine starts dependably every time.

This aftermarket unit matches the original starting-system requirements of the Mitsubishi engine family. It is manufactured with precision copper windings, a machined commutator and a splined output shaft for reliable engagement. The unit is stocked in-house, backed by a 1-year warranty with a 10-day dispatch lead time. Reliable cranking-torque design guarantees dependable start performance for your 24V vehicle.

Key physical specs: length 140 mm, outside diameter 53.5 mm, net weight 1 kg, supplied in a neutral kraft inner carton.

Mitsubishi 4D33 Engine and 24V Starting System

Mitsubishi engines rely on a correct starter armature match so the starter drives the flywheel reliably under normal electrical load and in cold conditions. This armature uses a 13-segment commutator and a splined shaft engineered to match the original Mitsubishi starter assembly, delivering stable operation after installation.

Technical Specifications

Engine Compatibility and Cross Reference

This starter armature fits Mitsubishi starter motors, including the 4D33 engine application. Do not rely solely on the application for fitment validation; always verify the original armature commutator segment count, winding, shaft spline, length and the starter OE number before ordering.

Multiple OE numbers exist across different production batches for this same armature family. If your original armature carries any one of the listed part numbers, the ME701492-series unit is a direct drop-in replacement.

What to Look for in a Replacement

Follow these five verification steps before placing your order to avoid wrong-part returns:

• 1. Check the nameplate data on your original armature: confirm the rated power is 3.7KW @24V. Different voltage or power ratings are not interchangeable.

• 2. Count the commutator segments: this unit has 13 PCS. An incorrect segment count will not match the starter brushes.

• 3. Measure the armature: length 140 mm, outside diameter 53.5 mm. A different dimension will not fit the starter housing.

• 4. Confirm your application is a Mitsubishi starter, including the 4D33 engine. Other applications use different armature assemblies.

• 5. Match the OE / reference part numbers stamped on your original armature or its packaging.

Application Scenarios

• Independent auto-electric workshops reconditioning Mitsubishi starter motors across Asia, Africa, the Middle East, Europe and Latin America.

• Parts counters and jobbers stocking Mitsubishi starting-system rebuild components.

• Starter re-manufacturers and rebuilders needing genuine-spec armatures for Mitsubishi starters.

• Fleet maintenance teams restoring vehicles to factory-standard condition.

• Used vehicle export traders supplying second-hand Mitsubishi vehicles to global secondary markets.

Installation Steps and Precautions

Armature replacement is an internal starter-motor rebuild task and must comply with the assembly specifications for low-voltage electrical equipment and the general requirements for engine starting systems. The following are standardized rebuild steps, including compatibility inspection and practical operation precautions, to ensure stable operation after installation.

Pre-Installation Preparation

• Power cut protection: Disconnect the negative battery cable before removing the starter from the vehicle to avoid short circuits.

• Tool preparation: Prepare a torque wrench, socket set, screwdriver, puller, commutator stone, micrometer, soldering tools and rags.

Component and Compatibility Inspection

• Confirm the new armature matches the original Mitsubishi starter assembly, including commutator segment count, shaft spline, length and diameter.

• Check that the armature windings have no broken or burnt coils, the commutator surface is clean and the shaft is straight.

• Inspect the starter field coils, brushes and bearings for wear; replace worn components before installing the new armature.

Cleaning the Rebuild Workstation

• Clean the armature and starter housing surfaces, remove carbon dust and debris from the commutator area, and reserve sufficient operating space for assembly.

Installing the Armature

• Firmly fit the armature into the starter housing, confirming the shaft aligns with the front and rear bearings without binding. Gently rotate the armature by hand to confirm it spins freely and the commutator aligns with the brush holder.

• Confirm the commutator runs true without run-out and the brush springs contact the commutator surface correctly.

Finalization and Functional Testing

• Reinstall the brushes, bearing end cover and drive assembly, then confirm all bolts are tightened to the specified torque.

• Reconnect the negative battery cable and conduct a no-load bench test: the rebuilt starter must spin freely without abnormal noise or sparking, and the drive gear must expand and contract normally.

• If abnormal sparking or noise appears, re-inspect brush seating, commutator surface and bearing alignment before installing the starter back on the engine.

FAQ

In Practice

For technicians rebuilding Mitsubishi starter motors: before ordering an armature, disassemble the starter and measure the original armature, recording commutator segment count, shaft length and spline type. Defective brushes, field coils, bearings or drive assemblies can mimic armature-failure symptoms, so do not replace the armature blindly. Always disconnect the battery negative terminal before commencing removal work.

During rebuild, dress the commutator with fine stone if lightly worn, check windings for continuity and insulation, and confirm shaft run-out with a micrometer. Fit the new armature, seat the brushes, and bench-test the starter before reinstalling on the engine. Tighten bolts to the Mitsubishi official workshop-manual torque specifications.
