Charging alternator enquiries for Weichai diesel engines. Match the original alternator number with your engine and equipment details before selecting a replacement.
The image is a catalogue reference. Exact specifications and fitment are confirmed for the quoted unit.
A Weichai engine alternator enquiry starts with the charging unit’s part number and the engine installation details. The engine drives this alternator to supply electrical loads and recharge the battery. This page covers the engine’s charging-system component; a generating set’s main power alternator is a separate item.
For a replacement quotation, send the original alternator label and engine nameplate. The catalogue image shows a pulley-driven alternator with mounting lugs and rear connections. It does not confirm the offered part number, voltage, current rating or engine compatibility.

Match the complete part reference, electrical specification and installation together. A similar housing or the same engine-series name is insufficient. Compare the original and proposed units using the applicable parts catalogue and equipment documentation.
| Check | Information to confirm |
|---|---|
| Part number | Complete alternator number, manufacturer markings and suffixes; engine model, serial number and equipment model. |
| Voltage | Label rating and the equipment’s charging-system specification. Use the approved reference to confirm compatibility. |
| Current | Rated output in amperes and the application’s required capacity; identify any proposed change from the original unit. |
| Mounting | Mounting ears, hole locations and diameters, housing orientation and available clearance. |
| Pulley | Pulley type, diameter, grooves and offset; check alignment with the existing belt drive. |
| Connections | Terminal markings, connector layout and the regulator or control interface specified for the equipment. |
DENSO’s replacement guide explains why pulley, mounting and connector positions need comparison. If another part number is offered, request its replacement reference and written fitment confirmation.
When the label is unreadable, add stamped markings, an old invoice or a parts-list reference. State which details are unknown and mention any previous engine or alternator replacement.

Before ordering, confirm the offered part number, manufacturer, condition and included components. Agree the price, availability, dispatch timing, packing, shipping terms and warranty for the specific offer.
The catalogue photograph does not establish a voltage rating. Check the original label, charging-system specification and approved replacement reference. Include the rating in your enquiry; the quoted unit’s voltage must be confirmed before ordering.
No. Also compare the electrical rating, regulator interface, pulley alignment and terminal arrangement. A mechanical fit alone does not confirm a compatible replacement.
Ask the equipment supplier or a qualified technician to review the proposed change against the charging-system requirements. A higher current rating alone is not evidence of compatibility, and the required output must still be met.
No. Battery condition, belt drive, wiring and ground connections can affect charging. Have the system diagnosed against the equipment service manual. DENSO’s troubleshooting overview describes these factors. The technical references on this page do not identify or certify the pictured unit’s manufacturer.
Confirm the supplied configuration in the quotation. Request an itemized contents list and current photos of the offered unit. Reference images do not define the delivery contents.
Use our Weichai parts buying checklist to prepare an order, or browse the engine parts catalogue. For the component that cranks the engine, see the starter motor product page.
Include the part number, engine model or serial number, quantity required, and destination country. Clear photographs of the engine nameplate and the old part can help explain what you need.
Use the engine series to browse the catalogue, then confirm the exact part number and engine details before ordering. A category listing alone does not establish that every listed part fits every engine in that series.
Include clear photographs of any markings on the old part and the engine nameplate with your enquiry. Describe the component you need and provide any available engine model or serial-number information.
