• Description:

  The W701183-S300 is a genuine Ford dowel bush built on the HM1 base, a precision locating sleeve that on starter applications also serves as a starter spacer, setting the starter motor's position and pinion engagement against the ring gear. Dealer catalogs carry it under the dominant names Dowel - Bush and Starter Spacer, filed in the starter-parts section, with catalog notes citing 2.3L applications. Documented sample applications where this exact service number is cataloged include the Ford Explorer, Mustang and Ranger and the Lincoln Continental, MKX and Zephyr, and the Mercury Mariner and Milan; treat those as representative examples rather than a complete vehicle list, because Ford reuses one locating bush across many engines and model years and does not publish a single finite fitment chart for it. As a starter spacer or dowel bush, it fixes the alignment between the starter and its mounting face so the pinion meshes correctly with the flywheel; when it is worn, lost or omitted, the starter can sit off position and produce grinding, poor engagement or hard starting. Replacing it with the correct genuine bush restores precise location and proper gear mesh. Because the suffix code denotes a specific bore, outside diameter and length, confirm fit for your exact vehicle by VIN before ordering rather than relying on the sample applications above.
