Application and Buying Notes

The main compatibility checkpoint on this Bosch unit is the part number 1986S00807, together with the 12V electrical rating, 1.9kW output, 10 tooth pinion, and clockwise rotation. Those details need to match the vehicle application and the removed starter before purchase, as starter fitment is determined by several measurements working together rather than one single feature.

Physical mounting points matter here because the unit is a 2 hole starter with 2 mounting bores, a 10.5mm mount hole diameter, 91mm mount centre to centre, and a 60mm flange diameter. The 248mm overall length and 28mm pinion diameter are also important reference points when checking clearance and engagement.

The listed fitment information points to Porsche Cayenne applications, including 2002 through 2007 sample models. Even with that guidance, confirm the existing starter’s part number, mounting layout, rotation, and pinion details against your vehicle before ordering. The dry clutch note should also be checked where the vehicle application requires that configuration.

For buyers comparing options, the most useful way to assess this starter is to line up the Bosch branding, 1986S00807 part number, and the measured dimensions against the original unit. If the vehicle has been modified, if a non-original starter has been fitted previously, or if the mounting face differs, the safest approach is to verify the dimensions and terminal arrangement before making a purchase.

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 1986S00807 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.

Relevant published details for this unit include Type STARTER MOTOR, Unit of Measure EACH, Warranty 12 Months, Mount Hole Diameter 10.5, Overall Length 248mm, Pinion Diameter 28mm, Rotation CW, Mount Cnt to Cnt 91mm, Wet / Dry Clutch Dry, Packaging length 32.5.

Bosch Starter Motor 12V 10Th CW. Part number 1986S00807 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 1986S00807, 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 PORSCHE CAYENNE, PORSCHE CAYENNE 2002, PORSCHE CAYENNE 2003, PORSCHE CAYENNE 2004. 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.

Compatibility note: Please confirm fitment with Part No. 1986S00807, the 12V / 1.9kW specification, 10 tooth CW configuration, and the listed mounting dimensions before ordering. Fitment should always be checked against the vehicle application and the starter removed from the vehicle.
