The ProForm 66791 is designed for home mechanics and professional shops who want an easy-to-read, durable dial to measure crankshaft degrees accurately. Its 9\" diameter gives enough scale to reduce reading error, and the included instructions walk you through common procedures so you can complete timing checks with confidence.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this tool help find top dead center (TDC)?\u003c\/h3\u003e\n\u003cp\u003eThe ProForm 9\" wheel provides a clear reference surface and graduated markings that let you rotate the crankshaft to the exact degree position. By aligning the pointer and the wheel’s markings, you can pinpoint TDC without guesswork. The accuracy of the printed scale reduces variation caused by smaller, harder-to-read dials.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e9-inch diameter for easier reading and finer incremental marks\u003c\/li\u003e\n  \u003cli\u003eHigh-contrast numbering for quick alignment\u003c\/li\u003e\n  \u003cli\u003eWorks with a center fixing bolt or hub to secure the wheel to the crank\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan I use the degree wheel to check camshaft timing?\u003c\/h3\u003e\n\u003cp\u003eYes — the wheel lets you mark and verify cam events relative to the crankshaft’s rotation. With the wheel fixed to the crank and the cam rotated, you can record opening and closing angles and compare them to target specs. This helps detect timing chain\/belt wear, incorrect installation, or cam phasing issues.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMeasure intake\/exhaust opening and closing angles\u003c\/li\u003e\n  \u003cli\u003eCompare measured values to manufacturer timing specs\u003c\/li\u003e\n  \u003cli\u003eUseful for chain\/belt replacement verification and cam swaps\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat accessories or steps are included to guide the process?\u003c\/h3\u003e\n\u003cp\u003eProForm includes a concise, step-by-step instruction sheet that covers basic setups and best practices for degreeing an engine.
