Ford 1.6L Ring Gear, 110 Tooth, 10.00" ID

The 10 inch ID, 110 tooth ring gear is the most common size for the Formula Ford 1600 engine.

This ring gear now has special double-chamfered teeth, designed to work with both Tilton (pre-engaged) and Lucas (inertia) starters. The ring gear should be installed with the chamfer on the leading side of the teeth, so that the starter teeth make contact with the flat side. That means the teeth on the starter side (the right side of the FF1600 engine) should have the flat side of the teeth facing down (towards the starter).

Note: Some later cars use a 10.12" ID 110 Tooth Ring Gear (Part No. 173-03), and some later British formula cars use a 132 tooth ring gear. Be sure to check your car before you order.
