Speedmaster Harmonic Balancer Timing Tape 5.25" to 8.00" PCE484.1001.01

The Speedmaster Harmonic Balancer Timing Tape PCE484.1001.01 is a precision measurement tool designed for engine timing work on harmonic balancers ranging from 5.25" to 8.00" in diameter. This adhesive-backed timing tape adheres directly to the harmonic balancer, providing clear degree markings for accurate ignition timing adjustments and diagnostics.

The timing tape enables mechanics and engine builders to quickly set and verify ignition timing without complex calculations. By wrapping the tape around the harmonic balancer and aligning the crankshaft pointer, users can read precise degree values for TDC (Top Dead Center) and firing point adjustments. The wide diameter range—5.25" to 8.00"—makes it compatible with most small-block and mid-size engine applications. This is an essential tool for carburetor tuning, spark plug timing verification, and engine performance diagnostics in repair shops and home garages.
