Application and Buying Notes

When replacing a starter motor, the safest approach is to match the part number 1986S00835 with the vehicle application and the existing unit on the vehicle. The confirmed product details here are 12V, 9 tooth, and clockwise rotation, and those points must line up with the required starter specification before you buy.

Do not rely on appearance alone. Starter motors can look similar while differing in voltage, tooth count, and rotation direction, and any mismatch can prevent installation or proper engagement. The 9 tooth count and CW rotation are especially important because they relate directly to how the starter engages the engine ring gear.

The Bosch description notes this starter motor is built to withstand the harshest environments, which is useful context for buyers wanting a durable replacement in demanding conditions. Even so, the warranty is 12 months, and the unit should still be checked against the vehicle’s requirements and the old part details before fitting.

If your existing starter has a readable label, compare the brand, part number, voltage, and rotation first, then confirm the tooth count. If any of those details are unclear, have the vehicle checked by a qualified parts interpreter or mechanic before ordering, as the fitment data provided here is not vehicle specific.

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 1986S00835 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 1986S00835 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 1986S00835, 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.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

Compatibility note: Confirm compatibility by matching Bosch part number 1986S00835, 12V specification, 9 tooth count, and clockwise rotation against the vehicle and the removed starter motor before purchase.
