Valeo Alternator 12V 180A Part No. 439836

The Valeo Alternator 12V 180A, part no. 439836, is a new rotating electrical unit supplied as each. It is a 12 volt alternator with a 180 amp power rating, a pad alternator mount, and direct fastening, which are the key details to check against the original unit before ordering.

This alternator uses a 6 groove pulley with a 50mm outside diameter, clockwise rotation, and no connector for revolution counter. Those features matter when matching the physical layout, belt drive, and plug arrangement on the vehicle.

Valeo is listed here as the brand and the unit is identified with pin code IR228. The alternator weighs 7.72kg and carries a one year warranty, so it is intended for buyers who need a replacement unit with the same basic electrical and mounting characteristics as the original part.

Application and Buying Notes

Before ordering, match the part number 439836 and the pin code IR228 to the original alternator, then compare the mounting style, pulley setup, and electrical connection. The important physical checks here are the pad mount, direct fastening, 70mm mount leg thickness, 9mm pivot hole diameter, and 9mm adjusting hole diameter.

The pulley arrangement also needs to line up with the vehicle’s belt drive. This unit is specified with a 6 groove pulley and 50mm outside diameter, so it should be checked against the existing alternator before fitment is attempted.

The rotation is clockwise, which is another point that should be confirmed against the original unit. If the replacement alternator has a different rotation direction, pulley section, or connector arrangement, it may not suit the application even if the vehicle make appears in the fitment list.

The alternator is rated at 12V and 180A, so it is designed for a higher output charging setup than lower-current units. That makes it important to confirm the vehicle’s original amperage rating rather than assuming all alternators in the same range are interchangeable.

Because the fitment information includes several Mercedes-Benz commercial and people-mover applications, the safest approach is to verify against the vehicle identification details, the original unit, and the physical measurements supplied here. Commercial vehicle alternators can differ by engine, charging specification, and connector arrangement within the same model family.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number 439836 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

Valeo Alternator 12V 180A. Part number 439836 should be checked first. Listed voltage is 12. Listed output rating is 180. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Pad. Pulley configuration is 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number 439836, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 180 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include 5-T 2006, 5-T 2007, 5-T 2008, 5-T 2009, 6-T 2009, 6-T 2010. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm compatibility using part no. 439836, pin code IR228, and the listed mounting, pulley, voltage, and connector details before purchase. Vehicle naming alone is not enough to confirm fitment.
