Review on Proform 66792 Dead Center Locater by Andy Baker

This is the right TDC tool for your engine. I removed the #1 spark plug and installed the piston stopper. Then I got under the truck, used a socket and ratchet, and turned the motor clockwise until it stopped turning. Marked the Harmonic Balancer. Then I turned the motor counterclockwise until it stopped and made a second mark on the harmonic balancer. Found 1/2 waypoint between two markers and made a third marker to indicate TDC. I revved the engine to the 3rd mark, then installed the distributor and lined up the rotor with the #1 wire on the spark plug. Jumped into the cab and tried to start the truck. BAMM! DIRECTLY BURNED! Works perfectly! I had no problems with the piston stopper. Screwed into the hole nice and neat, and the screw was easy to adjust. I have never bent a bolt, but I have turned the motor by hand. This tool is only intended to be used by turning the engine with a socket wrench and ratchet. I would recommend this piston stopper tool!
