Application and Buying Notes

Before buying, match the part number 1986S00806 and compare the starter’s key measurements against the unit already fitted to the vehicle. The important checks here are 12V, 1.7kW, 9 teeth, clockwise rotation, 2-hole mounting, 11mm mount hole diameter and 76mm flange diameter.

The supplied fitment information shows applications across Porsche 911, Boxster and Cayman, with Porsche 911 model years shown from 1997 through 2007. That does not remove the need to confirm the exact application, because starter fitment can vary by vehicle build and original equipment configuration.

If you are replacing a worn starter, it is sensible to compare the old unit side by side where possible. Overall length of 232mm, weight of 4.038kg and the dry design are useful checks when confirming the replacement will physically suit the vehicle and match the existing electrical setup.

Bosch notes this starter is produced to OE-level standards and uses optimised internals for maximum starting cycles and service life. Even so, the buyer still needs to verify that the tooth count, rotation direction and mounting pattern match the vehicle, as those details are what determine whether the starter will install correctly.

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 1986S00806 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.

For part number 1986S00806, 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 911, PORSCHE 911 1997, PORSCHE 911 1998, PORSCHE 911 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.
