cam timing wheel - cheap

Recommended Posts


I want to check some camshaft dimensions and angles,


so I thought I need to buy a degree wheel. Like a 360 degree protractor. to attach to cam pulley

Found one then realised it was for an American muscle car and like 9 inches in diameter.


A polo camshaft pulley is 132mm diameter.

Found one for minis, but not sure of the bolt size.



Then found a web app


that will create a custom degree wheel marked with your cam events (ATDC BBDC ACDC?) as a PDF to print at any diameter you want (almost). 

And suggests CD sized. (hint use the Print Diagrams button, turn off Fit to page when print the saved PDF )


So I did that and glued it to an old PCPro magazine CD..
