Bumper no longer worked. Did not extend far enough out, end worn out.

Unscrew the old one. Clean out the grass and dirt. Screw the new Bumper in.
Test the bumper. It took several bumps before it worked. It might be better
to clean out the entire trimmer head.
The only difficulty was grasping the old bumper to unscrew it. Wasn't much left of the old one.

Ryobi Bump Head Knob Assembly and Reel & Line assembly was worn out. Just needed new parts.

Just replaced the parts that I ordered and I was back in business with my electric Ryobi weed eater/edger. I've ordered these replacement parts before and have always been very pleased.
Thank you ereplacementparts.com

bump feed knob for troybuilt trimmer

Exactly as described, swift shipping, reasonably priced.

Rebuild

Fits and operates as good as new.

Guest - October 18, 2019 Verified Purchase

Easy Repair

A friend brought his Ryobi string trimmer to me and the original cap was completely worn out. This part arrived quickly at a fair price. I was able to fix it for him for $21.00 including tax and shipping.

Guest - October 9, 2019 Verified Purchase

First Order

The part was exactly what I needed . The process was easy.

Guest - October 7, 2019 Verified Purchase

I am so happy I found your sight. My 132r gave out in May. I bought a Craftman trimmer in June, it was awkward to use, heavy, for me and the line was always tightening up inside the spool and wouldn't come out when bumped, ( maybe me ). I put the new parts on, fit perfectly and I had my "old" trusty trimmer back, with the weight I can handle. My 132r is almost 25 years old. Thank You again.

I was a little apprehensive, ordering strange parts, however, they arrived somewhat quickly, and they fit and work perfectly.

Guest - August 30, 2019 Verified Purchase
