Q:

How to repair a Craftsman 22 inch electric hedge trimmer in which the cutting blades fail to cut 172.79957

A:

Thanks for the inquiry and for being a valued member.

The blade unit is available which would include the blade and all the cutting components including the eccentricity wheels preassembled. I am not sure if it will include installation instructions, but with it being preassembled, it should be easy enough to put together since you've already had the hedge trimmer taken apart. The part number is SB04.A.03-00.

I hope this helps and thanks for using SearsPartsDirect.com. We appreciate your business.

Thank you for your question. I will try to help you with the hedge trimmer. I think you are referring to the nuts that are along the cutting bar. If this is correct, there is not a torque spec on those nuts. They should be tight enough there is not a gap between the blades but loose enough that the blade can move. I like to tighten them up equally then back the nuts off until the blade moves free.

Please let me know if you need further assistance. Thank you for using Manage my life.

On the bottom side of the blade assembly there is a small flat black plate that attaches to the blade assembly and goes into the housing at the hand guard. This week, I noted that this plate is broken. Apparently, this happened awhile ago as there has been some play with the far end of the blade moving a little up and down. After using the trimmer a lot this past week, there is now some sideways play, too. Can the blade assembly be removed and this small plate be replaced? (I recognize the plate would probably not be from Sears.) Putting aside the time to replace the total blade assembly; a new assembly costs more than a new trimmer. Appreciate your help.
