Application and Buying Notes

Before ordering, compare the part number 1986S00865 with the starter being replaced. The listed specification is a Bosch 12V starter motor with clockwise rotation and a 10 tooth drive, so those details need to match the vehicle application and the removed unit before purchase.

The 2 mounting bores are another important check. Mounting pattern differences can prevent installation even where the voltage is correct, so it is worth confirming the mounting points, pinion tooth count, and rotation direction against the original starter.

This starter is described as designed to meet OE starters in fit and performance, but that does not replace vehicle verification. If the original part has a Bosch reference, comparing that reference, the 12V rating, and the 10 tooth CW configuration is the safest way to confirm suitability.

A 12 month warranty is included, which gives a clear reference point for after-sales coverage. Keep the invoice and part number details together, as that will help if the part needs to be checked later against the original application or any warranty enquiry.

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 1986S00865 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.

Bosch Starter Motor 12V 10Th CW. Part number 1986S00865 should be checked first. Listed voltage is 12. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 1986S00865, 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 starter motor in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

The listed warranty is 12 Months. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm compatibility by matching the part number 1986S00865, the 12V rating, clockwise rotation, 10 tooth drive, and 2 mounting bores to the original starter and vehicle application before ordering.
