Bosch Starter Motor 12V 10 Tooth CCW Part No. 1986S00801

This Bosch starter motor is a 12V unit with 10 teeth and CCW rotation, supplied as part number 1986S00801 and OEM number 02Z911023L. It is a starter motor supplied each, with a one year warranty, and it is intended for buyers who need to match the electrical specification as well as the pinion tooth count and rotation direction before ordering.

The unit is listed with 2 mounting bores and a 10 tooth drive, which are important checks when comparing a replacement starter. For applications where the starter has to match existing hardware and engagement characteristics, the voltage, tooth count, rotation and mounting bore count all need to align with the vehicle’s original arrangement.

Bosch describes this starter motor as designed in fit and performance to meet OE starters, with premium starting performance. It is manufactured in China and packaged with dimensions of 32.5 cm length, 13.9 cm height and 18 cm width, which may be useful for workshop handling and freight planning.

Fitment data provided for this part includes AUDI R8 applications across multiple model years. Even with that application information, buyers should still confirm the part number 1986S00801 and OEM number 02Z911023L against the vehicle’s existing starter and application details before purchase.

Application and Buying Notes

When replacing a starter motor, the safest checks are the part number, OEM number, voltage, tooth count and rotation. This unit is 12V, 10 tooth and CCW, with part number 1986S00801 and OEM number 02Z911023L, so those details should be compared with the existing starter before anything is fitted.

The mounting arrangement also matters. This Bosch starter motor has 2 mounting bores, which should be matched against the vehicle’s original starter and mounting pattern. A correct electrical match is not enough on its own if the physical mounting arrangement differs.

Fitment information supplied with this part includes AUDI R8 applications, but year coverage and exact vehicle matching can vary by build and application details. Use the vehicle identification details and compare them with the OEM number 02Z911023L, rather than relying on model name alone.

If you are ordering for workshop stock or a repair job with limited downtime, the packaging size of 32.5 cm by 13.9 cm by 18 cm may help with storage and freight planning. The starter is supplied each and carries a one year warranty, so it is a single replacement unit rather than a kit or pair.

Starter motors are a component where fitment is specific. A unit described as 12V, 10 tooth and CCW may look similar to another Bosch starter, but small differences in rotation, tooth count or mounting bores can stop it from being the correct replacement. Confirm those details before installation to avoid delays and unnecessary returns.

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 1986S00801 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 CCW. Part number 1986S00801 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 1986S00801, 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.

Available application references include AUDI R8, AUDI R8 2007, AUDI R8 2008, AUDI R8 2009. 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.

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

Compatibility note: Please confirm fitment by matching part number 1986S00801 and OEM number 02Z911023L with the vehicle’s existing starter and application details before ordering. The listed application information includes AUDI R8 models, but final compatibility should always be checked against the exact vehicle configuration.
