Questions & Answers for Gear Head


I am replacing the old string head assembly from 2019 with a 309562008. How do I get the old assembly off? Do I need a new gear head and string head adapter?
Bill for model number RY15523A asked on 2022-03-15
Hello Bill, Thank you for the question. No, the string head assembly is easily removed from the unit by twisting the retainer clockwise. This is a reversed threaded retainer. I hope this helps and good luck with your repair.

    So easy to replace the head of my weed eater. I was pleasantly surprised!
    I got a nice new head for my weed eater and had it up and running again in just a few minutes. Better then new.! It's a lot less expensive then getting a whole weed eater. I like to repair all my own equipment myself.
