• Locating Top Dead Center: Using our piston stop tool provides a precise mechanical stopping point. By physically stopping the positioning, the piston is blocked by the tool at the exact set position. This indirectly positions the top dead center (TDC)
• Product Specs: Contains 66792 top dead center tool*1 (with stud & joint), joint total size is 1*0.71*0.71 inch, outer thread diameter is 0.53 inch, stud total size is 2.52*0.39*0.39 inch, thread diameter is 0.37 inch, compatible with 14 mm spark plug hole
• Bolt-on TDC Tool: The bolt-on TDC tool utilizes the existing engine spark plug holes and screws directly into them without the need to cut additional holes. Plate bolts need to be used with the cylinder head closed and can be routed through the bore
• Added Strength: Zinc-plated carbon steel is used as the main material for the top dead center whistle. Carbon steel has high hardness to maintain functional stability under harsh working conditions, and the galvanized layer further improves service life
• Engine Repair: The top dead center tool is a cornerstone tool for engine precision repair, relying on the accurate positioning of the piston top dead center for both valve adjustment (valve lash alignment) and CAM indexing (camshaft timing positioning)
