Engine Compatibility and Cross Reference
This armature fits HATZ, JCB engines, KAMAZ-series and Mercedes-Benz ATEGO / CITARO / VARIO starter applications. Do not rely solely on the application for fitment validation; always verify the old armature OE number, voltage, power rating, spline count and dimensions before ordering.
| Equipment | Application | Typical Models |
|---|---|---|
| JCB | Engine | 4.4 [NA], 4.8 [TCAE] |
| HATZ | Engine | 1B40 0.5 |
| Truck / bus | Commercial | KAMAZ-series, MAZ, MZKT, Mercedes-Benz ATEGO / CITARO / VARIO |
Multiple OE numbers exist across different production batches, brand designations and market specifications for this same armature. If your original armature carries any one of the listed part numbers and the same rating and dimensions, the 16908993-series unit is a direct replacement.
What to Look for in a Replacement
Follow these six verification steps before placing your order to avoid wrong-part returns:
1. Check the rating of the original armature: confirm it is 24V 4.0KW. Different voltage or power ratings are not interchangeable.
2. Check the spline count: this unit has 15 splines. Confirm it matches your drive mechanism.
3. Check the commutator: this unit has 22 segments. Confirm it matches the brush set.
4. Verify the dimensions: 176 mm length, 62.5 mm outside diameter must match the original armature.
5. Verify the old armature OE number appears in the cross-reference list above.
6. Weight cross-check: a genuine matching unit weighs about 2 kg net; a significant weight difference indicates the wrong model or low-grade build quality.
Application Scenarios
Rebuilders and repair shops rebuilding starter motors for HATZ, JCB, KAMAZ-series and Mercedes-Benz applications.
Auto-electric specialists servicing no-start faults, weak cranking or commutator and brush wear issues.
Wholesale auto parts distributors and e-commerce sellers stocking starter armatures.
Fleet maintenance teams restoring starter assemblies to factory-standard condition.
Equipment operators maintaining commercial trucks and construction machinery.
Armature Rebuild Procedure
Armature rebuild must comply with the assembly specifications for low-voltage electrical equipment and the general requirements for engine starting systems. The following is a standardized rebuild procedure, including compatibility inspection and practical precautions, to ensure stable operation after installation.
Disassembly and Inspection
Disassemble the starter carefully, keeping the yoke, field coils, brush set, drive assembly and end covers in order.
Inspect the old armature for winding continuity, commutator wear, shaft damage and spline condition before deciding to rebuild.
Cleaning
Clean the commutator segments with fine emery cloth and remove any copper dust or contamination.
Confirm the winding is free of shorts and that the commutator segments are evenly worn and undamaged.
Assembly
Fit the new armature into the field frame, aligning the 15 splines with the drive assembly and the 22 commutator segments with the brush set.
Reassemble the brush holder, end covers and mounting hardware, and torque fasteners to the starter manufacturer specification.
Testing
Perform a no-load bench test at the corresponding voltage. For a 24V armature, test at 24V and confirm smooth, steady rotation with low current draw.
Confirm clean drive engagement and no abnormal noise. This rebuild must be performed by a qualified rebuilder using correct test equipment.
FAQ
Q: Does this armature fit my JCB, HATZ or Mercedes-Benz starter?
A: This 16908993-series armature is built for HATZ, JCB, KAMAZ-series and Mercedes-Benz ATEGO / CITARO / VARIO starter applications. Always confirm your starter model, old armature OE number, rating and dimensions before ordering.
Q: My old armature shows OE number 11131564 or VG1560090001. Will 16908993 work?
A: Yes. These OE numbers belong to the same 16908993-series armature family, differing only by format or production revision, so the 16908993-series unit serves as a direct replacement when the rating and dimensions match.
Q: Is this a new or remanufactured armature?
A: This unit is a new armature, built to original specifications and backed by a 1-year warranty.
Q: Can I rebuild my starter with this armature myself?
A: Rebuild requires technical skill and bench-test equipment. A qualified auto-electric rebuilder should perform the rebuild, bench test and installation.
Q: What is your warranty and lead time?
A: Goods are in stock with a 10-day dispatch lead time. A 1-year warranty applies from installation date; it excludes damage caused by improper installation, wiring errors or starting-system faults.
In Practice
For rebuilders working on HATZ, JCB, KAMAZ-series and Mercedes-Benz starters: before committing to an armature rebuild, bench-test the old starter and check the field coils, brush set, commutator and drive assembly. A faulty brush set, field coil or drive can mimic armature-failure symptoms, so confirm the armature itself is the cause. Always verify the armature rating and dimensions against the original unit.
Photograph and note the routing of the wiring during disassembly to avoid mis-assembly. Confirm the new armature is 24V 4.0KW with 15 splines and 22 commutator segments, and that length (176 mm) and outside diameter (62.5 mm) match. Assemble and bench-test at the corresponding voltage, then confirm clean gear engagement and low current draw before fitting to the starter.
