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

This Bosch starter motor is a 12V, clockwise-rotation unit with 11 teeth and part number 1986S00775. It is listed as new, supplied as each, and carries a 12 month warranty. The starter also has 2 mounting bores, an 11 tooth pinion, a 60mm flange diameter, and M8x1.25 mount hole diameter, so these details should be matched carefully before purchase.

Bosch notes this starter is manufactured to the same rigorous production standard as OE parts and is designed to deliver Bosch quality, long life, and high performance in extreme conditions. It is part of Bosch’s rotating electrical range and is manufactured in China. Those details matter when you are checking replacement suitability, especially where the original unit has a specific tooth count, rotation direction, or mounting pattern.

The listed dimensions give useful confirmation points for a replacement job: 90mm mount centres, 60mm flange diameter, 2 mounting bores, and M8x1.25 mount holes. In starter motors, these physical checks are just as important as the electrical rating, because a 12V starter with the wrong mounting face or rotation will not be a suitable substitute.

Application and Buying Notes

When replacing a starter motor, the safest comparison points are the part number 1986S00775, the 12V rating, the 11 tooth pinion, and the CW rotation. If any of those details differ from the unit being removed, the starter may not be suitable even where the vehicle model looks similar. The physical mounting details here are also specific: 2 mounting bores, 90mm mount centres A, 60mm flange diameter, and M8x1.25 mount holes.

This Bosch unit is described as a new starter motor, not remanufactured, and it carries a 12 month warranty. That combination may suit buyers wanting a direct replacement part with a clear warranty period. As always, warranty coverage is separate from fitment, so the key check is whether the starter matches the vehicle’s original specifications and application.

The fitment references supplied point to a wide Mercedes-Benz and Maybach application range, but that should be treated as a guide only. Starter motors are sensitive to mounting pattern, pinion teeth, and rotation, so the best practice is to compare the removed starter, the vehicle identification details, and the Bosch part number before purchase. If the original unit cannot be matched confidently, it is worth checking with a parts interpreter using the measurements 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.

Additional published details for cross-checking include Part No. 1986S00775, Brand BOSCH, Description Bosch Starter Motor 12V 11Th CW, Flange Diameter 60mm, Mount Hole Diameter M8x1.25, Rotation CW, New / Reman. New, Packaging length 32.5, Packaging height 13.9.

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 compatibility using Bosch part number 1986S00775 and the listed application and measurement details, including 12V, 11 tooth, CW rotation, 90mm mount centres, 60mm flange diameter, and M8x1.25 mount holes.
