Delco Remy Alternator 24V 275A 55SI Part No. 61006083

The Delco Remy 55SI alternator is a 24V unit rated at 275 amps, supplied as a new alternator under part number 61006083. It is listed with a pad mount, internal regulator, clockwise rotation, and no pulley section, so the key installation checks are the mounting style, shaft dimensions, and electrical setup before ordering.

This unit suits Delco applications as listed, and it carries an inside mounting legs measurement of 126mm, a mount centre-to-centre measurement of 190mm, and a mount leg thickness of 80mm. Those dimensions matter when comparing against the existing alternator or bracket arrangement, especially where the mounting face and leg spacing must match the vehicle setup.

As a 24-volt, 275-amp rotating electrical component, this alternator is intended for heavier duty charging applications where output, fitment geometry, and regulator type all need to line up. The shaft diameter is 22mm, the pin code is IR221, and the unit weighs 19.36kg, which gives a clear reference point when checking against the original unit already on the vehicle.

Application and Buying Notes

Before buying, compare the part number 61006083 and the alternator arrangement on the vehicle against the listed details: 24V, 275A, pad mount, internal regulator, and clockwise rotation. These are the main identifiers that help avoid ordering a unit that is physically similar but electrically or mechanically different.

The mounting measurements are especially important on this unit. Check the inside mounting legs at 126mm, the mount centre-to-centre at 190mm, and the mount leg thickness at 80mm, then compare them to the existing alternator and bracket layout. The 22mm shaft diameter and IR221 pin code should also be matched where the installation depends on the same connection and shaft configuration.

Because the pulley section is listed as not applicable, do not assume the pulley arrangement from another alternator will transfer across. The safest approach is to verify the original unit, confirm the 24V charging system requirement, and make sure the Delco application and mounting style match before fitting. The one year warranty applies to the supplied part, but it does not replace the need to confirm compatibility first.

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 61006083 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.

Delco Remy Alternator 24V 275A 55SI. Part number 61006083 should be checked first. Listed voltage is 24. Listed output rating is 275. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Pad. 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 61006083, 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 275 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

Compatibility note: Confirm fitment using part number 61006083, 24V 275A rating, 55SI series, pad mount setup, internal regulator, clockwise rotation, and the listed mounting dimensions before purchase.
