Bosch Starter Motor 12V 9-TOOTH CW Part No. 1986S00992

The Bosch Starter Motor 12V 9Th CW is a rotating electrical replacement starter supplied as each, with part number 1986S00992. It is a 12-volt unit with clockwise rotation and 9 teeth, which are the key identifiers to match against the vehicle’s existing starter and application details before ordering.

This starter motor is described as being designed in fit and performance to meet OE starters, with a focus on premium starting performance. It is also stated to be built to withstand harsh environments, which is useful context for buyers comparing a replacement starter for heavier-duty or demanding operating conditions.

The unit has 3 mounting bores and is manufactured in China. Packaging dimensions are 34.6 cm long, 19.4 cm wide, and 15.5 cm high, which may assist with freight planning or storage, but the critical buying points remain voltage, tooth count, rotation, and part number.

A 12-month warranty is listed. For an electrical component like a starter motor, confirming the part number, mounting arrangement, and rotation direction before fitment is the safest way to avoid return issues and installation delays.

Application and Buying Notes

When comparing starter motors, the most important checks here are 12V voltage, clockwise rotation, 9 teeth, and the 3 mounting bores. Those four details should line up with the vehicle’s original starter or the confirmed application record before you place the order.

The Bosch part number 1986S00992 is the clearest reference point for cross-checking. If your old starter has a different part number, different tooth count, or a different rotation direction, it is worth verifying compatibility carefully rather than relying on appearance alone.

This starter motor is positioned as a Bosch rotating electrical replacement with OE-style fit and performance. That makes it important to match the application correctly, because starter motors can look similar while differing in mounting pattern, rotation, and drive engagement.

The listed warranty is 12 months, and the unit is sold individually as each. If you are ordering for workshop use or fleet maintenance, checking the packaging dimensions of 34.6 x 19.4 x 15.5 cm can help with receiving and handling, but the fitment checks remain the priority.

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 1986S00992 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 1986S00992 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 1986S00992, 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 DEUTZ-FAHR DX, DEUTZ-FAHR DX 1978, DEUTZ-FAHR DX 1979, DEUTZ-FAHR DX 1980, FENDT FARMER, FENDT FARMER 1974.
