Denso Alternator 12V 40A DXA4106

The Denso Alternator 12V 40A, part number DXA4106, is a new alternator supplied as each unit for rotating electrical applications. It is a 12 volt unit with a 40 amp power rating, internal regulator, and a single leg alternator mount, so it needs to match both the electrical setup and the mounting style in the vehicle or machine.

Key physical checks for this alternator include a 62mm pulley outside diameter, 21mm mount leg thickness, 10mm pivot hole diameter, M8x1.25 adjusting hole diameter, and 138mm mount centre-to-centre measurement. The unit weighs 2.64kg, which is a useful reference when comparing against an existing alternator.

This alternator is listed for Denso units and carries pin code IR17. The quoted warranty is 12 months or 20,000km. As with any rotating electrical part, the part number and the measured mounting points should be checked against the original unit before ordering, especially where the vehicle or equipment has had previous electrical changes.

Application and Buying Notes

Before ordering, compare the part number DXA4106, the 12V voltage, and the 40A output with the original alternator fitted to the machine. The mounting details matter as much as the electrical rating here: a single leg mount, 21mm mount leg thickness, 10mm pivot hole, M8x1.25 adjuster thread, and 138mm centre-to-centre measurement all need to line up with the existing setup.

The pulley details are also worth checking. This alternator uses a 62mm outside diameter pulley with an A section belt profile, so belt alignment and belt type should be confirmed against the original unit. If the old alternator has been replaced before, measure the mounting points and pulley rather than relying on appearance alone.

The fitment list covers a wide range of compact machinery, forklifts, tractors, and equipment families, but that does not replace a direct check against the existing unit. The safest approach is to confirm the original alternator’s part number, pin code IR17, and mount dimensions before fitting. That is especially important where the machine has had electrical repairs, non-standard brackets, or previous conversion work.

This is a compact 2.64kg alternator with an internal regulator, so it is suited to applications originally built around that style of charging system. If the original unit uses an external regulator or different plug arrangement, the alternator may not be suitable without further verification. Matching the original specification is the most reliable way to avoid downtime and repeat removal.

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 DXA4106 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 12 Months 20000km, Mount Leg Thickness 21mm, Pivot Hole Diameter 10, Pulley Outside Diameter 62mm, Regulator Type Internal, Voltage 12, Mount Cnt to Cnt 138mm, Weight 2.64kg.

Additional published details for cross-checking include Product Group 1 ROTATING ELECTRICAL, Part No. DXA4106, Brand DENSO, Description Denso Alternator 12V 40A, Adjusting Hole Diameter M8x1.25, Pin Code IR17, Power Rating (Amp) 40, Pulley Section A, Suits Unit Make Denso, Alternator Mount Single Leg.

Denso Alternator 12V 40A. Part number DXA4106 should be checked first. Listed voltage is 12. Listed output rating is 40. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Single Leg. Regulator type is Internal. Pulley configuration is A. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA4106, 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 40 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm compatibility by checking the original part number, the DXA4106 identifier, the 12V 40A rating, the IR17 pin code, and the mounting and pulley measurements before purchase.
