Application and Buying Notes

Before ordering, match the part number VXA913 and compare the mounting layout against your existing alternator. The important checks here are the twin leg mount, 80mm inside mounting legs, 181mm mount centre to centre, M8 x 1.25 adjusting hole, and 10.5mm pivot hole.

The electrical specification is 12V with a 100A output and an internal regulator. If your machine uses a Valeo-type alternator and a phase connection, those details need to align with the replacement unit as listed.

Pulley detail also matters. This unit uses an A-section pulley with an 82mm outside diameter, so the belt profile and pulley size should be confirmed against the existing setup before purchase.

The listed fitment references are for Hyundai Construction equipment, including R55-7, R55-7A, R55-9, R55W-7, R55W-9, R60CR-9, R60W-9S, R80-7, and R80CR-9. Even with those references, physical comparison remains important because alternator mounts and pulley arrangements can vary between applications.

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 VXA913 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.

For part number VXA913, 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 100 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm compatibility by checking part number VXA913, Valeo unit make, 12V 100A output, twin leg mounting, 80mm inside mounting legs, 181mm centre to centre, and the A-section 82mm pulley before fitting.
