TDC Tools

This tool is made from an old spark plug core.  I have drilled and tapped the inside of the core and added a 3/8 pin.  The end of the pin is radiused where it contacts the piston. The tool has an air escape hole. The tool is used in conjunction with a degree wheel to locate TDC with total accuracy.  The use of the tool is described in my “how-to” section of my web site.  Tool is $20.00, with shipping and handling in the lower 48.  International, Alaska and Hawaii customers will be invoiced for shipping separately after you have purchased the product.
