This unit is supplied as an alternator only and uses an internal regulator, with a pad mount and direct fastening arrangement. It is listed as an excl. vacuum pump type, so the physical style needs to match the vehicle application before purchase.\u003c\/p\u003e\n\u003cp\u003eThe electrical specification is 150A charge current at 12 volts, with a 6 groove pulley section. Mounting dimensions listed are 8\/9.5 mm for both the adjusting hole diameter and pivot hole diameter. These details are important when comparing the unit against the existing alternator on the vehicle.\u003c\/p\u003e\n\u003cp\u003eA key compatibility point is that this unit will NOT replace a Valeo 120 Amp unit. That note should be checked carefully against the current alternator fitted to the vehicle, along with the part number 1986A00909 and the mounting and pulley details. Manufactured in Spain and supplied with a 12 month warranty.\u003c\/p\u003e\n\u003cp\u003eFor buyers comparing replacement options, the most useful identifiers here are Bosch brand, 12V, 150A, internal regulator, pad mount, direct fastening, and 6 groove pulley.

The mount type is listed as pad with direct fastening, and the pulley is a 6 groove type, so those details need to line up with the alternator already fitted.\u003c\/p\u003e\n\u003cp\u003eThis alternator is listed as excl. vacuum pump, which is a critical difference when matching replacement parts. It is also specifically noted that the unit will NOT replace a Valeo 120 Amp unit, so a direct swap should not be assumed just because the mounting points look similar.\u003c\/p\u003e\n\u003cp\u003eThe most practical way to avoid a mismatch is to compare the part number, voltage, amperage, pulley section, and hole sizes against the removed unit. The adjusting and pivot hole diameters are both listed as 8\/9.5 mm, which can help confirm whether the bracket and fixing arrangement are the same.\u003c\/p\u003e\n\u003cp\u003eIf the vehicle has been fitted with a different brand, different output rating, or a Valeo 120A alternator, stop and verify the application first. Alternators can look close in photos but still differ in regulator type, mounting style, and pulley configuration, so the exact specification matters as much as the model family.\u003c\/p\u003e\n\u003cp\u003eBefore 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.\u003c\/p\u003e\n\u003cp\u003eFor workshop, fleet, and equipment applications, accurate identification of part number 1986A00909 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.\u003c\/p\u003e\n\u003cp\u003eRelevant published details for this unit include Type ALTERNATOR, Unit of Measure EACH, Warranty 12 Months, Pin Code IR148, Power Rating (Amp) 150, Regulator Type Internal, Note This unit will NOT replace Valeo 120 Amp unit, Alternator Charge Current [A] 150, Alternator Type excl. vacuum pump, Packaging length 28.\u003c\/p\u003e\n\u003cp\u003eAdditional published details for cross-checking include Packaging height 22.5, Product Group 2 ALTERNATORS, Part No. 1986A00909, Brand BOSCH, Description Bosch Alternator 12V 150A, Adjusting Hole Diameter 8\/9.5, Pivot Hole Diameter 8\/9.5, Pulley Section 6 Groove, Voltage 12.\u003c\/p\u003e\n\u003cp\u003eBosch Alternator 12V 150A.

Pulley configuration is 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.\u003c\/p\u003e\n\u003cp\u003eFor part number 1986A00909, 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.\u003c\/p\u003e\n\u003cp\u003eFor a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 150 should be checked carefully.
