Hi Deejay59. We are definitely going to need a picture, probably more than one. This is the HR194 and HR214 blade mounting as shown in the workshop manual:

We need pictures of yours to see how it is different. Some of the safety features vary from country to country, and we will probably need to get comments from other people when we see your pictures, especially if they are different from the workshop manual diagram.

You said that the blade holder retaining bolt is bent. I do not see how you could tell that it is bent, since it screws fully into the end of the crankshaft. If you mean that its head runs out of true when the crankshaft rotates, it seems more likely that the crankshaft is bent. You can check this by seeing whether the outside of the clutch drive disk runs out of true. If it does, the crankshaft is bent. Fixing that requires stripping the motor, and straightening the crankshaft under a press. As well as the press and suitable press tools, V blocks, a dial indicator, and considerable skill are required to check how true the crankshaft is at frequent intervals as you try to straighten it. In essence, if the crankshaft is bent you should consider whether you can obtain a good second hand crankshaft. If you can't, your engine should probably be considered beyond repair, at least by a private owner with no special skills or equipment.
