Bosch Starter Motor 12V 11 Tooth CW Part No. 1986S00775

Bosch Starter Motor 12V 11 Tooth CW, part number 1986S00775, is a new rotating electrical component supplied as a single unit. It is a 12 volt starter motor with clockwise rotation and 11 teeth, so matching the electrical and engagement details to the vehicle application is essential before purchase.

The unit uses a 60mm flange diameter, 90mm mount centres, and two mounting bores with an M8x1.25 mount hole diameter. Those dimensions are the key checks when comparing against the existing starter, especially where the original unit has been removed and the replacement needs to line up correctly on the bellhousing and mounting points.

Bosch lists this starter motor as manufactured to the same production standard as OE parts, with optimised internals for starting cycles and service life. It is covered by a 12 month warranty and is manufactured in China.

Application and Buying Notes

When comparing a replacement starter, the most important checks are the part number 1986S00775, 12V voltage, clockwise rotation, and 11 tooth pinion. The physical mounting details also matter here: 90mm mount centres, 2 mounting bores, 60mm flange diameter, and an M8x1.25 mount hole diameter.

This starter motor is listed against several Mercedes-Benz application groups and Maybach application groups, but the exact vehicle match still depends on the vehicle’s original starter specification. Where a vehicle has had previous repairs or engine changes, confirming the removed unit against the dimensions and part number is the safest approach.

Bosch identifies this unit as new and supported by a 12 month warranty. That makes it suitable for buyers who want a direct replacement style starter, but the fit still needs to be confirmed against the vehicle’s existing application details and the hardware dimensions listed here.

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 1986S00775 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 11Th CW. Part number 1986S00775 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 1986S00775, 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 5-T 2006, 5-T 2007, 5-T 2008, 5-T 2009, 6-T 2006, 6-T 2007. 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 12 Months. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment using part number 1986S00775, 12V, CW rotation, 11 teeth, and the mounting measurements before ordering. The listed application groups are a guide only, and the final check should always be made against the vehicle and the original starter motor.
