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.

Worn out parts for an old string trimmer.

I appreciate the ease and efficiency with which I received the parts that I needed. Best of all they work, so I didn't half to buy a new trimmer.

Guest - April 13, 2020 Verified Purchase

Had nearly given up

I needed a new bumphead for my old line trimmer. I tried many different local businesses. No one could help. Next I got on Internet where I found this website where I put in the order,paid and waited. After getting regular tracking updates the part arrived. Exactly what I had hoped for. Thank you.

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

Easy repair.

Looking to get my string trimmer a few parts that I was missing and was glad you had them available to me.
