Application and Buying Notes

When replacing a starter motor, the safest check is to match the part number 1986S00700 against the original unit or the confirmed application for the vehicle. This Bosch starter is a 12V, 1.4kW, 9 tooth, clockwise-rotation unit, so those details need to line up with the existing starter and the vehicle’s requirements.

Mounting dimensions are just as important as the electrical rating. This starter lists a 106mm mount centres measurement, 76mm flange diameter, 227mm overall length, and M10x1.5 / 11 mount hole diameter. It also uses a 2 hole mount design with 2 mounting bores, so the fixing pattern should be checked carefully before purchase.

The pinion details also need attention during identification. The pinion at rest is 25.5mm and the pinion diameter is 29mm. On starter motor replacements, small differences in tooth count, flange size, or mount layout can prevent a proper installation even when the vehicle appears similar.

The listed fitment coverage includes BMW 3 applications for 2001 through 2006. That is useful as a guide, but the exact vehicle should still be confirmed against the part number and the starter’s dimensions, especially where build dates, engine variants, or transmission configurations may differ.

This starter motor is listed as OE-quality in fit, appearance and durability, and it is supplied with a 12 month warranty. That gives a clear quality and coverage reference, but it does not replace application checking. If the existing starter is still available, comparing it side by side is often the quickest way to confirm the correct unit.

Because this is a rotating electrical part, correct identification before fitting matters for both time and cost. Check the voltage, rotation direction, tooth count, mount type, and the overall physical measurements listed here to reduce the chance of ordering the wrong replacement.

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 1986S00700 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 9Th CW. Part number 1986S00700 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 1986S00700, 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.

Compatibility note: Please confirm compatibility using part number 1986S00700 and the listed application details, including 12V, 9 tooth, CW rotation, 106mm mount centres, 76mm flange diameter, 227mm overall length, and the 2 hole mount pattern before ordering.
