Man i've spent two days and several hours on youtube and manuals trying to figure out if i need to buy a new tube. I was about to order one when I saw this. Thank you!
Just have to say, I was working on the Stihl FS38.. was stumped like a 10,000 year old tree. I search online for basically half the day. I just stumbled across your video and you showed me exactly what I needed. That stupid hidden hex screw under the guard. Never even saw it, my problem was the flex cable came out of the channel. Me removing that hex screw allowed me to reseat the flex cable into the head. Now it works like new.. thank you for the good explanation of that screw..
This video saved me about $100 in service and parts charges. My bearing was fine, but the flexible drive shaft had somehow disengaged it. Couldn't figure out how to get bearing out and finally did, pulled shaft out and re-engaged, put back together and back to work.Before, the head would barely spin and would completely stop if went to cut.
My trimmer sucked up some fishing line and melted in the bushing, seizing it up. I ground off the existing stihl retaining ring with a dremel, and got a E-type circlip from a hardware store. I had a feeling the E-type would pop off, but needed to get the machine running so I just installed it. It worked for about 45 minutes and then popped off. However, disassembling and cleaning seemed to fix my issue so i'm not that upset about having to buy another ring!
thanks. it took me a while to figure this out on my own. but less time than it took me to find this video. lots of bad info floating around on the web re. the fs45. this is the good info. I found the part on ebay.
Had one where bearing kept overheating and melting trimmer head.I put grease into bearing and it solved the problem.Took me ages to figure out how the bearing is released.
Awesome, additionally if your all the way apart, chances are the cable may have came out of the plastic routing piece on the motor side. A quick zip of the T25's at the head, you can string it back in the center as it should be, then reinstall through bearing and secure everything...
FYI that screw hole is also how you grease them, just use chainsaw bar grease gun and 1-2 pumps and done. Do it every year, last 5x longer then not. doing
im just about making a modification for this , using ball bearings, I cant understand how a company like Stihl uses a bronze bearing on a part that rotates up to 8000 rpm in an abrasive enviroment .....
Thanks for the video. My bearing is a bit loose up and down. I removed it per the video and will either replace it or try the suggestion of lubing the bearing, but I have two questions. Once the bearing shaft is removed the cable moves out of position so you just can't push the shaft in. How do I get the cable to line up again so I can reinsert the shaft? Other questions is how do I lube the bearing if I want to try that. Thanks!
I have 2 perfect fs45 Stihl trimmers, both needing the bearing retainers as yours was. I wish I could fix them. The ‘nut’ came loose. It’s knurled on the shaft, stupid design. And they’re $48 a piece right now :(
Quick bearing test: Hands and arms still vibrating after weed whipping? After weed whipping touch the end of the metal shaft near the guard. Did you get burnt? If so, replace shaft bearing! Or find a means to grease it. Unless the bearings actually wore.
Coolyards - I have the same model. I had the dealer replace the spool with a new spool. Now the spool does not rotate. Of course I couldn't get it started after I brought it home and took the handle apart, so I'm reluctant to bring back to the dealer in case I screwed something up. Any ideas why the spool might not rotate? Perplexed.
How did you manage that? Mine came apart and I can't seem to figure it out. It's either too tight and the head won't spin, or it's too loose and it falls right off. I can't believe that's how it's held together.

Well done mate, from an Aussie. Answered the q perfectly.
Cheers mate🍻 your hours of research meant my research only took 2 minutes 👌

Thanks for taking the time. Perfectly explained what is wrong with my FS 45.
Brilliant! I thought I could replace this part but, until I saw your vid I wasn't sure.

Short and to the point, thanks
Thank you so much I thought I had to buy the hole shaft.

Grease the bearing through the screw that holds the guard bracket on.
Thanks , not going to get burned by Stihl dealer

I replacing these brand new bearing twice a yr sometimes Im.finding something else To expensive to have something mess up all the time
Is there a way to tell if the bearing is bad or a drive shaft is bad when the motor runs but the head does not turn?
How does the flexible steel shaft attach to the bearing?
thanks man hahaaa was so easy
what size is the torque screw that holds the head on? lost it and am having a hard time trying to replace it
Stihl part# 9022 313 0930 M5x8mm
Catfish Jerry me too

On a side note; why not just add a xerxes fitting?

Awsome Dude from a Kiwi , another tip, pull the cable out a tad so its easy to fit the new head bearing. Cheers.
Coolyards. How do you remove the bearing housing
the set screw
Thank you. Rather than replace the clutch that gets stuck I can just reattach the flexible shaft. 10 minutes of work.
thanks !!!!!!!!!!!!!!!!
I have a straight shaft one piece...can i switch it out with an attatchment type shaft...anyone try it
can anyone tell me how to get the bottom off the head so I can put different blades on without replacing the entire head?
Manual.
Just " FIXED " mine, didn't have to replace anything.
How did you manage that? Mine came apart and I can't seem to figure it out. It's either too tight and the head won't spin, or it's too loose and it falls right off. I can't believe that's how it's held together.
WHERE ? on ebay can you get these shaft bearings ??
search for 4140 640 1402
Dang, was wishing this had been answered.:( Ebay is just a jumbled mess and out of it all, no bearing :*(
Do you have any idea how fucking long I have been trying to lock my shaft for a fs38 ? Thank you very much.
The price recently dropped & even confused my dealer, the part is now $34 new.
Found a new part on Amazon for 16 bucks
How do I get the drive shaft to come out of the spindle piece??
The driveshaft is a flexible 1/4" cable? It simply pulls out of a 1/4" hole....
This has to be the worst engineering I have ever seen. Stihl should be ashamed of this trash. Whoever came up with this design deserves a beating
Whats wrong with it? Better then Husqvarna where you have to replace the whole shaft and you can grease the bearing on the Stihl.
