Questions & Answers

what size reverse tread bolt on the spool retainer.
todd for model number r430
Hi Todd, sadly the reverse tread bolt is not sold as individual piece and we do not have further information on the part. You would have to buy the entire spool retainer in order to get this part. Thank you for your question and good luck with your repair!

Socket set, grinder
Spool retainer stuck, can't be removed
Lent my trimmer to a family member ..... while attempting to replace trimmer line, he did not realize that the spool retainer was reverse - threaded and tried to turn the spool retainer counter clockwise until the red plastic housing was damaged. I had to grind away red plastic housing with grinder to expose the spool retainer bolt. Once the bolt was exposed, I removed it with socket and replaced it with the new spool retainer assembly. REMEMBER.... SOMETIMES BOLTS ARE REVERSE-THREADED.
