This is a Dynamite Piston Locking Tool, and is intended for use with all engines. Conventional piston locking tools can damage or break pistons if too much force is applied. This new Crankshaft Locking Tool from Dynamite allows you to avoid this hazard by locking the rod and piston in place from the back of the engine! The new tool is machined from Delrin and will not mar internal engine components.

Dynamite Crankshaft Locking Tool .12/.21
Broke on first use. Plastic blew apart while tightening flywheel nut. Switched back to the old method of jamming the rear end of a toothbrush between the crank counterweight and the crankcase, and the nut still spun another 1/4 turn, meaning that this tool gave up before full torque was reached.

This tool works excellent for safely locking the piston in place while cranking down on the nut to hold the flywheel in place. There is simply no better way to assemble a nitro engine. Without this tool, plan on taking your engine apart a couple times to re-tighten everything.
