Selection Criteria: What to Check Before Buying

Buyers should work through each of the following criteria to confirm that the JFZ280-3002 is the right alternator for their application.

1. OEM Part Number Match

The most reliable starting point is the OEM part number stamped on the existing alternator or listed in the vehicle's parts manual. This unit is catalogued under OEM 202V26201-7271. If your current alternator or parts book shows a different number, verify cross-reference compatibility before ordering.

2. Vehicle Application Compatibility

This alternator is designed for Heavy Duty Truck MAN D20 Series applications. Confirm your truck's engine family before selecting this unit. If your vehicle is a MAN D08 series or a Howo T7H, the related product with OEM 202V26101-7278 (JFZ2980ZH1, 28 V / 80 A) may be the correct match instead.

3. Voltage Rating

The JFZ280-3002 operates at 24 V. Heavy-duty truck electrical systems commonly run at either 12 V or 24 V. Installing a 24 V alternator on a 12 V system — or vice versa — will damage vehicle electronics. Verify the nominal system voltage from the truck's service documentation before ordering.

4. Rated Current Output

The rated current of this unit is 80 A. Evaluate your truck's total electrical load — engine management systems, lighting, telematics, and auxiliary equipment — to ensure 80 A is sufficient. If a higher output is required, HEBEI JINLITONG AUTO PARTS CO.,LTD. also offers heavy-duty truck alternators rated at 110 A (e.g., OEM 0124655039, article JFZ2110280A for Mercedes-Benz trucks) for reference on current scaling.

5. Pulley Specification

The pulley fitted to this alternator is 8PK78. The drive belt on the engine must match this pulley groove count (8PK) and effective diameter (78 mm). A mismatch will cause belt slippage, premature wear, or installation failure. Check the existing belt or engine accessory drive specification.

6. Physical Dimensions and Mounting

The unit measures 0.26 m (W) × 0.255 m (H) × 0.21 m (L). Before ordering, measure the available space in the engine bay and confirm that the mounting bracket pattern and connector positions align with your vehicle's configuration. Dimensional data should also be cross-checked against the original alternator if possible.

7. Packaging and Order Quantity Flexibility

For procurement teams or distributors evaluating a first purchase, the minimum order quantity is 1 PCS. Packing options include neutral packaging, colored packaging, or personalized packaging as required by the customer — a useful consideration for businesses that resell or stock parts under their own brand.
