Application and Buying Notes

Before ordering, match the part number 1986S00703 and confirm the vehicle application against the original starter. The key matching points here are 12V electrical system, 1.4kW output, clockwise rotation, 10 teeth, 2 mounting bores, M10 mount hole diameter, and 246mm overall length.

The pinion at rest is listed at 26mm, and the starter is specified as a dry clutch unit. Those details are worth checking against the removed starter, especially where the vehicle has had previous repairs or non-original components fitted.

The fitment references supplied for this part include Chrysler Crossfire and multiple Mercedes-Benz passenger and van applications. That said, starter motor matching should still be verified against the exact vehicle build and the existing unit, because physical configuration and terminal arrangements can vary even within the same model range.

This Bosch starter motor is supplied as an individual unit, so it is best compared directly to the original starter on the vehicle before installation. Confirm the mounting bore count, mount hole diameter, flange size, and rotation direction to reduce the risk of an incorrect match.

A 12 month warranty is supplied with this part, which gives a clear service period for normal retail use. Keep the purchase details and part number 1986S00703 for reference if you need to compare the unit later or discuss the application with a parts specialist.

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 1986S00703 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.
