If you are out there trimming your grass with your STIHL curved shaft weed eater and all of a sudden that the line head falls off on the ground. Do not worry about it. Here is a detailed guide on how to fix it.

Reason

There is a reason that the little clip came off. If you look at the end of this little shaft carefully, you can see a groove. If you see on the top of that groove, you will see it is just tapered on the top where the clip should be catching. You may find it is worn out. Therefore, if you just pop that all back together again, it is going to come off as well. And the part of the bearing is still stuck at the end of the tube while the other part is in the line head. The bearing can simply come apart as there is a little clip on the backside.

How to fix

Step 1: First of all, you have to reuse the clip. You need to get the two parts out of the shaft and the line head. And get them off from the line head and the tube. You have to take the line head off to pull the part out of the line head.
Step 2: you need to get the guard off. Take off the screw that holding the guard so that you can pry it off the shaft. You can see that there is a little tiny screw at the end of the shaft. You have to take it out to pull the bearing out. Sometimes bearings are really tight while some of them come out really easily.
Now you have taken the bearing outside, so you have every piece where it came apart. You can reuse the clip if it is good.
Step 3: Before you do that, you have to square up the top edge of the groove again to make sure the clip would not come off ever again. You can use a hacksaw blade to cut it and roll it around. Keep cutting and rolling until you see the square edge.
Step 4: Now it is time to reinstall the assembly together as it should be. And then put the bearing back to the tube as well as the guard and the line head.
