Oops, I got that wrong. When you hit the cam it relieves the
stresses on the surface and causes it to curl away from where it is
struck. Of course, you will have to keep checking it and move around
to hit it at different spots. The chisel should be curved and blunt
to spread out the blow. You should hold the cam and push gently in
the direction it should move. This is one of those operations that
would be easier after watching an old time machinist do it.<br>

It is not difficult to straighten cams yourself. You can do it
with a blunt cold chisel and hammer, but I prefer to use an air
hammer with a blunt rounded chisel. Use V blocks and a dial
indicator to check it and decide where it is bent. You hit the cam
between the lobes, which relieves the stresses and causes it to
curve up. It seems counter intuitive, but that is the way they
bend. It has been a while since I've done it, but I believe that
is how it's done with these cast iron blanks. If it still doesn't
fit, then have it ground to fit as Greg suggested.<br>
