This tool (FCP-TA-18549) is designed to align and hold the crankshaft of your Ford engine at Top Dead Center (TDC) for correct timing chain installation. Without this tool, you can cause significant damage to your engine Pistons and Valves if the crankshaft rotates during Timing Chain Removal and adjustment!

• This tool is specifically designed to align the crankshaft at Top Dead Center (TDC) on Ford 1993-newer 4.2L and 4.6L 2-valve engines, 1993-newer 4.6L 4-valve engines, and 1993-newer 5.4L and 6.8L V8 engines.
• These Ford engines are not Free Wheeling engines meaning that if the crankshaft is rotated during timing chain installation (Jumped Timing), it can cause significant damage to the Pistons and Valves if the cylinder heads are not removed.
