I have a dewalt circular saw, and was making a cut in a really dumb way and had a pretty significant kickback. The blade was pretty obviously bent so I replaced it, but now with the new blade on the blade rubs on the guard. The blade seems solid and and straight, no wobble or anything. The saw sounds right, other than the scraping on the guard. The guard does not appear to be bent (I don't know how the guard would get bent in a kickback anyways)...it's pretty solid and won't bend easily - I've tried to bend it away from the blade, unsuccessfully. It *seems* like maybe the whole shaft has shifted out a 1/4 inch or so...is that possible? Has anyone seen something like this before?
Circular saw damage after kickback?

Is your guard bent or out of line?

As the motor is held in the body, and the spindle seems to be okay, then if it's a spindle problem, then the motor in the body would have to have been bent or twisted off of it's supports, and that would very likely damage the bearings as well. If the blade had bent, then it would have bent inside the guard, so it's more likely to be a guard issue. I've had a couple of circular saws with Riving knife, but they don't seem to be so common nowadays. Is there a local shop that you can go and have a look at one.
Post some pictures though

Here's a few pics. The guard must've bent I guess, although it doesn't look bent...everything looks aligned correctly, just the blade is sitting like a 1/4" out from where it should (relative to the guard). I tried to show the spindle in the pics...you can see it *maybe* looks like it came out a bit? I've never really paid much attention to how much it sticks out before tho...

The guard actually looks okay, and is straight. It almost looks as though in picture 2, the sprindle assembly has shifted toward the outer part of the guard, and that would suggest the bearing assembly may have been knoocked out of the body.

Looking at the first photo the blade looks parallel to the base. Best way to check would be with a vernier caliper.
Next thing I'd do is use a dial indicator on the furthest ends of the blade against the base and by hand turn the blade to make sure the Arbor isn't giving run out.
As long as the motor is turning and the blade isn't running out too much and the blade itself is parallel to the leading edge of th base it's the blade guard that's damaged.
The 'outer' guard is fixed to the motor housing so there's a slim chance that's damaged. The self retracting section however is often crap on most saws and I'd consider that's the problem.
Have you tried to cut since? Mark a straight line and follow it with the base, if the blade binds it's the motor Arbor what's damaged.
