Removing or torquing stubborn flywheel nuts, primary gear nuts, and clutch hub assemblies often requires locking the engine in place. Attempting to do this by jamming a rag into the primary gears or using an unstable holding tool can cause severe damage to the engine internals.\u003c\/p\u003e\n\u003cp data-path-to-node=\"2\"\u003eThis simple but highly effective \"piston stop\" tool threads directly into your 14mm spark plug hole. When the engine is slowly turned over by hand, the top of the piston gently bottoms out against the rounded, non-marring tip of the tool. This locks the crankshaft securely in place, allowing you to easily apply a breaker bar or torque wrench to the engine's external nuts without the engine spinning out of time.\u003c\/p\u003e\n\u003ch4 data-path-to-node=\"3\"\u003eFeatures:\u003c\/h4\u003e\n\u003cul data-path-to-node=\"4\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,0,0\"\u003e\u003cb data-path-to-node=\"4,0,0\" data-index-in-node=\"0\"\u003eSafe Crankshaft Locking:\u003c\/b\u003e Provides a secure, non-destructive way to stop the crankshaft from turning while applying high torque to flywheel or clutch nuts.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,1,0\"\u003e\u003cb data-path-to-node=\"4,1,0\" data-index-in-node=\"0\"\u003eNon-Marring Tip:\u003c\/b\u003e Features a rounded, smooth contact point designed to rest against the piston crown without gouging or punching through the soft aluminum.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,2,0\"\u003e\u003cb data-path-to-node=\"4,2,0\" data-index-in-node=\"0\"\u003eEliminates Gear Damage:\u003c\/b\u003e Replaces the risky practice of jamming rags, pennies, or screwdrivers into the primary gears to stop engine rotation.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,3,0\"\u003e\u003cb data-path-to-node=\"4,3,0\" data-index-in-node=\"0\"\u003e14mm Threading:\u003c\/b\u003e Precision machined to perfectly match standard 14mm spark plug threads found on the vast majority of modern and vintage full-size 2-stroke dirt bikes.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4 data-path-to-node=\"5\"\u003eWhat's in the Box:\u003c\/h4\u003e\n\u003cul data-path-to-node=\"6\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,0,0\"\u003e1x Steahly Offroad Engine Lock-Up Tool (14mm)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4 data-path-to-node=\"7\"\u003eFitment Notes:\u003c\/h4\u003e\n\u003cul data-path-to-node=\"8\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"8,0,0\"\u003e\u003cb data-path-to-node=\"8,0,0\" data-index-in-node=\"0\"\u003e2-Stroke Engines Only:\u003c\/b\u003e Fits 2-stroke engines utilizing a 14mm spark plug (commonly replaces NGK BR-series or B-series plugs).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cmeta charset=\"utf-8\"\u003e\n\u003cp data-path-to-node=\"12\"\u003e\u003cb data-path-to-node=\"12\" data-index-in-node=\"0\"\u003e4-Stroke Warning:\u003c\/b\u003e We cannot stress this enough: piston stop tools are exclusively for 2-strokes. A 2-stroke combustion chamber is an empty dome, meaning the tool rests cleanly against the center of the piston. A 4-stroke has intake and exhaust valves extending down into the combustion chamber. If you thread this tool into a 4-stroke head and turn the crankshaft, the rising piston will push a delicate valve directly into the this tool, potentially bending the valve and requiring a complete cylinder head rebuild.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"13\"\u003e\u003cb data-path-to-node=\"13\" data-index-in-node=\"0\"\u003eManual Operation Only:\u003c\/b\u003e Once the tool is threaded into the two stroke cylinder head, gently turn the engine over \u003ci data-path-to-node=\"13\" data-index-in-node=\"101\"\u003eby hand\u003c\/i\u003e using a socket on the flywheel or primary nut until you feel the piston make solid contact with the tool tip.
