INSTALLING THE TIMING TAPE
1. Locate the top-dead center or 0° mark on the harmonic
balancer or timing wheel.
2. Select the correct timing tape for your application. Make
sure you know the correct size of the harmonic balancer
or timing wheel you’re using. If this is not known, measure
the diameter of the harmonic balancer or timing wheel’s
edge and note the size.
3. Choose the timing tape that matches your balancer’s
diameter. Be sure that the mating surface is clean of any
dirt, grease or debris. Locate and note the 0° mark on the
timing tape (Figure 8).
4. Align the 0° mark on the tape with the TDC mark on the
balancer. Make sure that the markings on the tape are

pressure for proper adhesion. ATC (after top-dead center)
