What is the rotation of my starter motor? OBB Starters

05.15.2018

This is by far the most popular question we receive. The answer is very simple – keeping in mind that each tooth on the gear has a beveled (slanted) edge. To determine your starter’s rotation:

Point the drive of the starter away from you or pointed straight up as pictured below.

(#1 pictured below): If the beveled edge is on the right (slanting from right to left), it has a clockwise or CW rotation.

(#2 pictured below): If the beveled edge is on the left (slanting from left to right), it has a counter clockwise or CCW rotation.
