Repairs HRR2167VKR broken blade holder

Hi there,

My HRR2167VKR mower made a horrible sound this morning. Sounded like the blades were hitting something. I looked underneath and took the blades off.

Here's a picture: 2015-09-26 12.41.37.jpg

The blade holder appears to be broken. Looks like it is replaceable, but I can't get the center bolt out. I've tried an impact wrench.

Questions:
1) Is it a normal thread, counterclockwise to loosen (lefty loosy)?
2) Any tips on getting it off?
3) When I replace it, how much torque should I apply to the bolt?

Any other tips and advice are appreciated. There doesn't seem to be a lot of info on this procedure here or elsewhere that I can find.

thanks
- John
