Harmonic Balancer Covers
These patented harmonic balancer covers offer improved
readability, more stable Top Dead Center indication and timing
accuracy, enhanced appearance for a previously ignored
underhood area, and the elimination of timing tapes which are
inevitably flung off. They are available in chrome and black, resulting in parts with the appearance of $200 balancers. Each
cover is distinctively marked with the famous Bowtie Emblem,
Top Dead Center and the proper timing degrees. Using this
cover improves timing accuracy because over time the etched
outer inertia ring of a typical harmonic balancer may slip in
relation to the center hub of the balancer, causing the etched
markings to provide an inaccurate indication of Top Dead
Center for the #1 piston. Mounted directly through the center
hub, this cover eliminates the affect of any outer inertia ring
slippage. Aluminum. U.S. Patent 5,675,078.
