SKU: L12 Category:



This is Ford’s most prevalent starter since 1991. Rebuilders call it PMGR (permanent magnet gear reduction). When you dis-assemble it, you’ll notice the man made magnets instead of electrical fields and the 3 planetary gears in the middle.  The kit gets its name from the smallest terminal on the solenoid and the 12 teeth on the bendix. Click on the pic of the solenoid, you’ll notice the small post terminal is on the left. (the starter lead wire post is on the bottom, the main battery terminal post is at the top). Thus L12 means Left 12 teeth. The L12 kit is common on Taurus 3.0L (not DOHC eng.) Note : starters before 1995 have a push on terminal spade but must be updated to post style. Cut off spade from existing harness and install new ring terminal. This starter occurs on ’91-’96 Tracers and Escorts with 1.8L.

Kit includes: Solenoid, bendix, brush holder ass’y, bushings and snap rings.
