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.

Question: Bumphead Knob Assembly 791-18146...

pfinlay

The replacement part does not have the embedded nut to thread the knob onto the spindle, making the part useless.

Hi pfinlay Search around on ebay for possibly the part that has the embedded nut in it.

Question: Bump Knob

Ibby

I have a Ryobi 705r and the string went short then inside, how do I fix this? I tried taking the bump knob off but I can't seem to get it and every video I find just glosses over it, any ideas?

Hello Ibby,

If you can find a way to stop the spindle from turning, the 791-181468B Bump Head Knob Assembly, will thread right off.

Question: 105r

Rocketpad

I have a Ryobi 105r that the bump head needs replaced. It says the one will work but it doesn't look like the original at all. The original is flater and has a screw coming out of the bottom. Can you confirm it will work before I order? Thanks
