Application and Buying Notes

Before ordering, compare the part number MXA9610 and OEM number 139-7850 with the unit being replaced. Alternator fitment is often confirmed by a combination of the mounting style, pulley layout, regulator type, and electrical rating, not just by the vehicle or machine name.

For this alternator, the important checks are the 24V system voltage, 35A output, Mitsubishi style body, twin leg mount, 55mm inside mounting legs, 175mm mount centre-to-centre, and 84mm AA pulley. If any of those measurements differ from the existing unit, it is worth rechecking the application before fitting.

The pulley and rotation details also matter. This alternator is clockwise rotation with an AA section pulley, so belt profile and drive direction should be confirmed against the original unit. The pivot hole diameter is 12.5mm and the adjusting hole is M8x1.25, which are useful when checking bracket alignment and bolt sizing.

Because this is an internal regulator alternator, it is important to confirm that the charging system on the vehicle or machine is set up for that style. The listed weight of 5.82kg and the stated pin code IR134 may also help when comparing replacement units side by side.

The fitment listing supplied for this item includes Caterpillar applications such as 307C, 307CSB, 307D, 308CCR, 308DCR and 308DCRSB, with year references shown for some 307C and 307CSB entries. Use those applications only as a guide alongside the part number and measurements, not as the only check before purchase.

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 MXA9610 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.
