Question about Troy Bilt Tiller Bolens Swivel Post Pn 2126

Open Question

Hi, the entire cutting head fell off/ out of the shaft housing on my Bolens trimmer BL110.there is a square bolt that goes into a fitting on the cutting head but it will not stay secure. As always it fell apart when in use and for the life of me I could not locate any pieces that appeared to come from the trimmer, nor does it have any sort of detailed assembly diagram in the manual.How do I fix this? Am I missing a piece?

SOURCE: line stuck inside head of troy-bilt trimmer

Take an awl or small diameter screw driver, same size or a bit smaller dia. than the line dia., and push it through the hole from the outside of the line head. This should push the piece of old line through the hole.
Recommendation: Leave at least one inch of line on the inside of the head, so you can grab it easily when you have to replace the line. I'll carry a pair of long nose pliers on me when I use my trimmer, so I can easily grab hold of the inside piece to pull it through.

the knob is left hand thread so to get it off you will have to turn it as it you are doing it up
if you want the whole head of the shaft , there will be a clamp/screw/retaining bolt that you remove and pull the whole lot off the shaft

The head on my Bolens BL110 weed eater is slipping

Check the drive shaft. Within the drive tube there is a tightly sprung drive shaft, check where this connects to the head of the cutting attachment, it could have a worn drive.

I have a Bolens BL110 starts fine but dose'nt rev at all

Bolens trimmer sputters and stalls and only runs on half choke? Here's how to fix it.
Look on the top of the carburetor and you will see 2 black screws that are mostly round with a flat side recessed in the aluminum housing. They are flat on top and have no notches to insert a screwdriver. The trick is to turn these two screws 1/4 turn counterclockwise. I have a set of precision pliers and used the fine tipped needle nose to turn them.
The other option is to try and notch the top of them enough so you can use a flat blade screwdriver. You can grind down the surrounding aluminum with a Dremel tool so you can access them better.
You can see in the picture that I scratched across the top of the screws as a reference to see how far I was turning them.

How to fix my echo gt200r gas trimmer I was trimming with it and it got hook on a vine. Then when I engaged the throttle it spun for a second and then stopped, tried a couple more times and it did the same...

remove the head from the shaft( tube) and remove the broken drive cable
get and fit new cable and then reattach the head to the shaft ( tube )
the gears in the head are fairly robust but the drive is a cable which twists up and pulls out of the drive squares at either end

Cannot disassemble Troy-bilt trimmer head

There is a round, rotary black part between the metal piece to which the cutting head attaches and the outer plastic seat of the cutting head. There are two square slots, each about a quarter inch wide, on opposites sides of the black piece. Slide an Allen wrench or something similar firmly into the slot. Holding the Allen wrench in a stable position, turn the outer plastic ring of the cutting head (it has scalloped edges that can be gripped firmly) counter clockwise to unscrew the cutting head from the bolt on which it is mounted. Be careful with the tool (e.g. Allen wrench) used to hold the black piece steady, as it is plastic and could be damaged by the edge of the tool.
