Application and Buying Notes

Before ordering, compare the part number 1986A00727 with the existing alternator and check the mounting layout carefully. The key measurements provided here are 82mm inside mounting legs, 163mm mount centre to centre, a 12mm adjusting hole diameter, and an M10x1.5 / 10 pivot hole diameter.

The pulley details also need to match the vehicle setup. This unit uses a 55mm outside diameter pulley with an 8 groove pulley section, and it is listed as clockwise rotation. If the belt drive, pulley section, or rotation differs from the original unit, the alternator may not suit the application.

This alternator is rated at 12V and 90A, with an internal regulator and an alternator type excluding vacuum pump. Those items are important because the charging system, regulator arrangement, and physical packaging all need to align with the vehicle's original configuration.

The product notes recommend checking the associated V-Belt or V-Ribbed Belt as an additional repair item. That is sensible whenever the charging system is being renewed, because belt condition and alternator fitment go together and a worn belt can affect charging performance.

Fitment information is shown for IVECO and IVECO VERTIS applications, including IVECO VERTIS 2010. Even so, the safest check is to confirm the vehicle details against the part number and the mounting and pulley measurements before placing the order.

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 1986A00727 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.
