Application and Buying Notes

For starter motors, the important checks are voltage, rotation, mounting pattern, and part number. This unit is 12V, 9th clockwise, and has 3 mounting bores, so it should only be matched to a vehicle that needs those same basic details. The part number 1986S10071 is the safest reference when comparing against an existing starter or parts catalogue.

The fitment data supplied for this Bosch unit points to Fiat Ducato applications, with years shown from 1997 to 2007. That gives a useful starting point, but model year alone is not enough for a final match. The same vehicle range can use different starter setups, so the old starter should be checked for the same mounting bore count and rotation direction before the replacement is confirmed.

The listed features are practical rather than decorative. Bosch states the starter is designed to meet OE starter fit and performance and to deliver premium starting performance. In real-world terms, that means the replacement should be assessed on the hard details first: electrical rating, rotation, mounting points, and physical clearance around the housing. The packaging size of 34.6 cm by 15.5 cm by 19.4 cm may also help when checking freight handling or storage space.

If the vehicle currently has a Bosch unit or an OEM-style replacement, matching by part number and application is the most reliable approach. If the existing starter is missing, damaged, or unreadable, compare the vehicle application carefully and verify the 3 mounting bores and 12V specification before purchase. That extra check is especially important on commercial-style vehicles such as the Fiat Ducato, where variant differences can affect starter compatibility.

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 1986S10071 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.

Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a starter motor passenger in workshop, fleet, trade, agricultural, or construction service, the listed electrical specification should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include FIAT DUCATO, FIAT DUCATO 1997, FIAT DUCATO 1998, FIAT DUCATO 1999. 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: Please confirm fitment using the vehicle application details, part number 1986S10071, 12V rating, 9th clockwise rotation, and 3 mounting bores before ordering.
