Questions & Answers

how do i remove string head adapter and the flanged washer from the gear head on a Ryobi ry253ss I bought a gear head replacement and now I need the parts from old gear head
David for model number ry253ss
Hello David, thank you for your question. The string head adapter is a left hand thread part so you would turn the part clockwise to loosen and left to tighten the adapter. Good luck with your repair!
location of trimmer adapter ?
Michael Balcita for model number RY253SS
Hello Michael, thank you for your inquiry! The adapter is located under the gear head. If you refer to the diagram for your model RY253SS, it is #7 on the diagram (located in the bottom left corner). I hope this information helps!
Are there female threads at both ends of this part 678019002? The trimmer I own needs to be threaded onto the shaft itself, and the spool retainer is a nut so that needs to be threaded in as well. I got the replacement but the spool retainer would not come off, so I had to saw it off, rendering the string head adapter useless now. Help!!!
Joel for model number RY34440 (S430)
Hi Joel, part 678019002 has two female threads on both ends, this adapter goes onto the gear head 308210009. Thank you for your question and good luck with your repair!

Stringhead adapter broke it was old and just snapped off.
My trimmer took it apart for me as it exploded apart. It's a gas trimmer. The repair was easy. Step one: Figure out how the string head goes together. That's the part that holds the line.
Step two : I slowly started to screw the pieces together-remember this is left hand thread so it's backwards righty loose lefty tighty. Step three: Use the correct socket and tighten the whole head up. Thats it. Took me 15 minutes.

String trimmer bump head wouldn't feed any longer and spindle was bent
The bottom of my bump head was worn down to nothing and I couldn't get it to come off. I'm not sure whether I continued to tighten it when I tried to remove it, but on a straight shaft (not curved) trimmer, you have to loosen clockwise, so once I finally took it off I separated the housing from the main spindle, which wasn't damaged.

I simply replaced with a whole new replacement housing and string attachment and counter clockwise tightened it on. Works like a charm.
