This unit is listed with twin leg alternator mounting, 40mm inside mounting legs, an M10x1.25 \/ 11 pivot hole diameter, an M8x1.25 adjusting hole diameter, and a 6 groove pulley with 55mm outside diameter.\u003c\/p\u003e\n\u003cp\u003eThe listed application includes Toyota Corolla with 1ZZ-FE engine, and the fitment data also references Toyota Celica and Toyota Corolla applications. Because alternators can vary by engine, mount style and pulley setup, the part number and physical dimensions should be confirmed before ordering.\u003c\/p\u003e\n\u003cp\u003eThis unit is manufactured in South Africa, supplied each, and carries a 12 month warranty.

For this Bosch unit, compare 1986A00451 and OEM number 0124315029 with the removed alternator, then check the twin leg mount, 40mm inside mounting legs, M10x1.25 \/ 11 pivot hole, and M8x1.25 adjusting hole before fitting.\u003c\/p\u003e\n\u003cp\u003eThe pulley setup is another critical checkpoint. This alternator has a 6 groove pulley with a 55mm outside diameter, so the belt arrangement on the vehicle needs to match. If the pulley groove count or size is different from the original unit, the alternator may not be the correct replacement even if the connector looks similar.\u003c\/p\u003e\n\u003cp\u003eThe listed output is 12V and 80A, which suits the application only when the vehicle’s charging system is designed for that specification. Alternators should be selected to match the original electrical and mounting arrangement rather than by appearance alone.\u003c\/p\u003e\n\u003cp\u003eThe listing also notes recommended additional repairs of V-Belt \/ V-Ribbed Belt. When an alternator is being replaced, the belt condition should be checked at the same time, as wear or glazing can affect charging performance and belt life.\u003c\/p\u003e\n\u003cp\u003eFitment data points to Toyota Corolla with 1ZZ-FE engine, and also references Toyota Celica and Toyota Corolla applications. That is useful as a guide, but engine code, mount style and pulley details still need to be confirmed against the vehicle already in front of you.\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 1986A00451 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, Inside Mounting Legs 40mm, Pivot Hole Diameter M10x1.25 \/ 11, Pulley Outside Diameter 55mm, Regulator Type Internal, Voltage 12, Mount Cnt to Cnt 170mm, OEM Number 0124315029.\u003c\/p\u003e\n\u003cp\u003eAdditional published details for cross-checking include Packaging length 23.9, Packaging height 20, Product Group 2 ALTERNATORS, Part No. 1986A00451, Brand BOSCH, Description Bosch Alternator 12V 80A, Adjusting Hole Diameter M8x1.25, Pin Code IR115, Power Rating (Amp) 80.\u003c\/p\u003e\n\u003cp\u003eBosch Alternator 12V 80A. Part number 1986A00451 should be checked first. Listed voltage is 12. Listed output rating is 80. These details form the core reference points used by parts interpreters when confirming the correct replacement.\u003c\/p\u003e\n\u003cp\u003eMount style is Twin Leg. Regulator type is Internal. 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 1986A00451, 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 80 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.\u003c\/p\u003e\n\u003cp\u003eAvailable application references include TOYOTA CELICA, TOYOTA CELICA 1999, TOYOTA CELICA 2000, TOYOTA CELICA 2001. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.\u003c\/p\u003e\n\u003cp\u003eThe listed warranty is 12 Months. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompatibility note:\u003c\/strong\u003e Confirm fitment using part number 1986A00451, OEM number 0124315029, the twin leg mount, and the 6 groove 55mm pulley before ordering.
