How do I align it so the timing is correct? Do I find tdc and put the missing tooth on near the crankshaft position sensor? thanks

Since the flex plate has the center broken out of it I can't just put the replacement back on like it was, I want the missing tooth to align with the cks correctly. This is a major job for me and I only want to do it once.

The missing tooth should then be located 90 degrees AFTER TDC (observe correct direction of engine rotation). In other words, the missing tooth should be at the CKP sensor at 90 degrees BTDC.

Steve Thanks for the info Steve, but did you mean to say" in other words, the missing tooth should be at the ckp sensor at 90 degrees after tdc."? I'm a little confused, just trying to understand.. i appreciate the help Les

Or, put #1 at TDC on compression stroke, then rotate the crank either by 90 degrees (1/4 revolution) backwards or forward by 1 3/4 revolution and the missing tooth should be at the CKP sensor.
