Question about Ryobi Garden

1 Answer

Bump head screw lost. Cannot find a rpelacement that fits.

I have a Ryobi 390r gas trimmer. The top of the bump head assembly came off and I lost the screw that keeps the assembly together. I spent over an hour with three different associates at Home Depot and we could not find a screw that will fit into the assembly. The screw hole does not look like it is damaged.

Try going to an outdoor power and equipment store of some kind. They will probably have what you need.

Repair manual for ryobi line trimmer rlt900


Jerry,

That number is not the model number for the trimmer, which always starts with RY. It is the number for the "bump head assembly" which is considered an accessory. They made 3 for this application as follows:
  • Bump Head Assembly, RLT1000, RLT900, RLT1004K
Once you determine your correct trimmer model number you can go to the link below and find your manual. Hope this helps.

Ryobi 26cc gas trimmer. Can't replace line. Used 1 8'' line thru slots in spool. (3'' each side). Don't understand next step. Push down spool and twist? Should spool stay level...


You line up the head with "arrows" by turning the plastic bump knob on extreme bottom. When arrows line up with the head then you insert your line through the slots "OR" you insert the line in one side and it comes out the other side. Then you have to push pressure DOWN ******* the bump head while twisting the bump head clockwise to "pull in" the string until there's only about six inches left remaining on the "shortest" piece hanging out the side. use scissors to make the lines equal in size before staring the trimmer. Hope this helps.

Ryobi Reeleasy line trimmer head PROBLEM


sounds like the clip isn't engaging properly. For a bump and feed they have steps that lock when enough cord is set out. If the head is not locked when its on it will recoil in. Try to make sure its not sitting wrong.

How do u remove the bump feed spool from the bump feed string head on my ryobi gas trimmer


Grasp the outer portion of the cutting head in your left hand and turn the inner knob with your right. Depending on model, some bump knobs are threaded and some are post and notch. Use a little spray like wd40 to loosen the mechanism. It may take a firm hand, but the two will separate so that you can reload the line. Consider reloading with the .095 five sided line. It cuts much easier than the round line.

Remove the trimmer head from shaft


The entire trimmer assembly (from the gearbox forward) will slide off of the drive shaft cover. On the side of the aluminum gearbox assembly, you will find a single screw. This is the "anti-rotation screw" (do not lose this). Then remove the small (approximately 1" diameter) clamp from the end of the gear box assembly and simply pull the entire cutting assembly off of the shaft.

If you just want to remove the trimmer bump head assembly, then you will need to lock the bump head assembly to prevent rotation while you are working. If you purchased this new, then there should be a small metal rod included with your accessories. This will fit in a small hole in the base of the gear box assembly 791-182193 and prevents the trimmer head from rotating.

Then proceed to remove the following items:

791-180814B (replaces 791-180814) Bump Head Knob Assembly
791-147495 Inner Reel (hold the trimmer string)
791-610636B (replaces 791-610636) Spring
791-612026 Retainer (be careful removing this so you do not inadvertently destroy it). If you intend to reuse the trimmer head. If not, then hack, pry, stab, etc.. until you mangle it enough to remove.
791-683301 Outer Spool & Eyelet Assembly should now slide out leaving only 791-612483
Spool Shaft which I will assume that you want to keep.


I replaced my entire string head assembly a couple of years ago (and subsequently misplaced it and am in fact wanting to purchase one) and replaced it with a grass-gater or similar.

I hope this helps.

Replacing the cutting head on Ryobi string trimmer.


There is a nut above the head, place a wrench on the nut then unscrew the head from the shaft, unless yours is different from mine this is how it works. I hope this helps.
