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 10 teeth on the bendix. Thumb on the 2nd picture, 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 L10 means left 10 teeth. 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.
Kits include New solenoid, bendix, brush holder ass’y, snap ring ass’y, and 2 different sized bushings (only one will be used)
