Trying to get the primary clutch bolt out with no success.

-Broke a clutch holding tool while using a breaker bar to loosen
-Cordless 20 volt impact will not loosen it.
-Air impact at 125 pounds will not loosen it. (Pancake compressor)

Lefty loosen threads.

Any ideas? Don’t want to break the bolt.

Don't know for sure about the 2021 450, but all the previous 400's used a left hand thread for the clutch.
So......righty loosen threads.

Yes, the 400’s are left hand threads. The 450’s are right hand from everything I’ve read and watching videos (Hunter works).

According to the parts listing for that machine, the primary bolt part # is 420641812.
Here is a picture of that bolt on Partzilla.

Looks like a left hand thread to me.
