Denso Alternator 24V 150A – Part No. 211-8009

This Denso alternator is a 24V, 150A unit supplied as a new alternator under part number 211-8009. It uses an internal regulator, a twin leg mount, and a brushless design, so the key buying checks are the voltage, amperage, and mounting dimensions rather than assuming a universal changeover.

The listed mounting measurements are 101mm inside mounting legs, 198mm mount centre to centre, a 13mm pivot hole diameter, and a 1/2 UNC adjusting hole diameter. The shaft diameter is 22mm and the pulley section is not applicable, which makes the physical mount details especially important when matching it to an existing application.

It is described as a compact and lightweight alternator at 11.04kg, with premium cores and precise OE assembly benchmarks. The product is backed by a one year warranty and is sold each, which gives workshop buyers a clear part reference when ordering replacement rotating electrical components.

Application and Buying Notes

Before ordering, compare the part number 211-8009 with the alternator you are replacing, then check that the vehicle or machine uses a 24V electrical system and a 150A alternator. The internal regulator and twin leg mount are important details, because a close-looking alternator can still differ in regulation type or bracket arrangement.

The physical dimensions matter just as much as the electrical rating. Confirm the 101mm inside mounting legs, 198mm mount centre to centre, 13mm pivot hole diameter, 1/2 UNC adjusting hole diameter, and 22mm shaft diameter against the unit already fitted. These measurements help avoid avoidable mismatches at installation.

The pulley section is listed as not applicable, so pulley arrangement should be checked against the application rather than assumed. The unit is brushless and new, and it carries a one year warranty, but those details do not replace a proper fitment check on the machine already in service.

Where fitment is being matched to a fleet or workshop record, use the verified application references as a guide and still confirm the exact alternator on the equipment. Variations can exist within the same make and model family, so the safest approach is to match the part number, voltage, amperage, and mounting measurements before purchase.

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 211-8009 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.

Relevant published details for this unit include Type ALTERNATOR, Unit of Measure EACH, Warranty One Year, Inside Mounting Legs 101mm, Power Rating (Amp) 150, Regulator Type Internal, Suits Unit Make Denso, Note Brushless, Mount Cnt to Cnt 198mm, Shaft Dimension 22.

Additional published details for cross-checking include Product Group 2 ALTERNATORS, Part No. 211-8009, Brand DENSO, Description Denso Alternator 24V 150A, Adjusting Hole Diameter 1/2 UNC, Pivot Hole Diameter 13, Pulley Section Not Applicable, Shaft Diameter 22mm, Voltage 24.

Denso Alternator 24V 150A. Part number 211-8009 should be checked first. Listed voltage is 24. Listed output rating is 150. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is Internal. Pulley configuration is Not Applicable. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number 211-8009, 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 24 and output 150 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching part number 211-8009, 24V system voltage, 150A output, internal regulator type, twin leg mounting, and the listed mounting dimensions against the existing alternator and application details before ordering.
