Denso Alternator 12V 130A 101211-8380

The Denso Alternator 12V 130A, part number 101211-8380, is a new pad-mount alternator with an internal regulator and a 130 amp output. It is listed as a Denso unit with a 12 volt system, brushless design, and a weight of 10.98kg, which gives a clear starting point for checking replacement requirements before purchase.

Key physical details include 108mm inside mounting legs, 190mm mount centre to centre, 13mm adjusting hole diameter, 13mm pivot hole diameter, and a 22mm shaft diameter. Those measurements matter because alternators that look similar can still differ in mounting and shaft dimensions.

This unit is supplied as each, carries a one year warranty, and is described as new rather than remanufactured. It sits in the rotating electrical group and is identified by Denso part number 101211-8380, so matching that number against the vehicle application is the safest way to confirm the correct replacement.

Application and Buying Notes

Before ordering, match the Denso part number 101211-8380 and confirm the mounting layout against the existing alternator. The important checks here are the pad mount style, 108mm inside mounting legs, 190mm mount centre to centre, and the 22mm shaft diameter, because those dimensions determine whether the unit will physically install correctly.

The electrical specification is equally important. This alternator is rated at 12V and 130A, so it should only be considered where that charging output and system voltage are appropriate for the application. The internal regulator and brushless design are useful identifying details when comparing to the unit already on the vehicle.

Vehicle references associated with this part include Ford Transit, Freightliner Century, Caterpillar CT Series, Sterling Trucks A-Line, and Western Star 4700 and 4800 among others. Even with those references, the correct buying decision still comes back to the exact application details, mounting points, and part number match on the existing unit.

This alternator is listed as new and weighs 10.98kg, so handling and installation planning should take that into account. If the current alternator differs in shaft size, hole diameters, or mount spacing, do not assume interchangeability based on appearance alone. Measure the old unit carefully and compare all listed dimensions before fitting.

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 101211-8380 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.

Denso Alternator 12V 130A. Part number 101211-8380 should be checked first. Listed voltage is 12. Listed output rating is 130. These details form the core reference points used by parts interpreters when confirming the correct replacement.

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

For part number 101211-8380, 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 130 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm compatibility by matching part number 101211-8380, the 12V 130A specification, and the listed mounting dimensions to the existing alternator and vehicle application before ordering.
