Problems after hitting brick

[kmsmth278]

I have a 5 year old Yard Machine gas lawn mower with a B&S engine. I hit a brick today and it cut off. The blade isn't bent, but it doesn't turn properly. It will turn easily for a little bit but then it gets hard to turn and makes a squealing noise before turning easily again. The flywheel pin isn't sheared but it does appear to have a crack. I need to get a puller kit because I can't get the flywheel off but I'm not sure if this is the problem.

The crankshaft doesn't look bent. It doesn't wobble or move at all. I centered a laser dot on the bolt and turned the blade. The laser dot stayed dead center on the bolt the whole time.

Also, if I remove the spark plug, the blade keeps making the squealing noise but turns freely.

Any ideas on what the problem is?

does the piston go up and down?

IT makes things a lot easier if we know exactly what we are dealing with
The possible problems are different if this is a walk behind or a tractor ?

you may have bent the spindle shaft. remove mower belts and turn by hand to see if spindle shaft is bent

If it still runs , no need to pull the flywheel, squeeling sounds would be a pully or belt, will need more information on what kind of mower this is
