This might sound stupid, but I figure better safe than sorry.
I'm researching adding a crank trigger wheel behind my crank pulley. It would be sandwiched between the pulley and the timing belt sprocket. I found a Ford one which has a very close bore (32mm - CA is 30). I plan on putting a bushing to reduce the size of the bore to 30mm. Here is a picture of what I'm talking about.
This trigger wheel is 3/16 wide, which means the crank pulley would be out a little further. I would also have to grind off the lip below the sprocket for clearance. It's the part in the square.
Other than being careful to not grind into where the oil pan seals, is there anything I should know before I do this?
Thanks
