- I needed to replace a bearing from the lower gearbox of a STIHL FS 56 trimmer
After a long period of time, this bearing failed
Piece numer is 95030039853, type 609-2Z
Advice: buy an original one, do not use any bearing type 609; the rotation speed is very high, so we need a bearing to withstand the forces

I loved the visual instructions, which were extremely helpful and like that there was no audio to the video even more - Thx
Top tip. If you heat the housing right where the bearing sits it will drop right out. And in when you assemble 😉
Yes works a treat, that's how we do it 😊
You made removing the bearing in 2:20 look easy. I ended up breaking metal pieces around the housing and just through it to the trash. Love the video thought!
Yeah I am also at this step where that tap pushes out all the gears and bearing (no bearing in the tube where the shaft goes in)..my bearing is still in there(it is in the round part of the head were the spindle came out)..I can see little balls covered in grease so I know it must have exploded..now how to pull that bearing out..?? Looks like it is in there pretty tight.(this is a older FS 55) Got the only bearing I could see out of the trimmer..now were to get the parts for a head that only had the one bearing..or maybe just buy a new gear box..
Also noticed that my bearing is in the top part of the head..and not a sealed unit like this one.
Good stuff! I like the way you emphasized on throwing away the old bearing, i sensed i high level of frustration being released and i laughed so hard😂😂😂
I got new idea from you to remove front bearing. It is difficult to take it out if it is stuck firmly. Thanks
Great help. Thanks.
There are 3 bearings in some of them. The two that were replaced in this video aswell as one in top of hat 🎩. Make sure an put the gear grease in to the head too.
"Safety washers" known as circlips in English. A safety washer is usually a lock washer - serrated or friction.
I see 2 bearings here correct? And only one replaced? If I'm wrong let me know, would like second part number for the other.
Don't forget there's 3 bearings in there . 1 on the driveshaft side and 2 on the cutting head side
Nice heavy duty bearing
are there non stihl bearings available
The clearing saw has been used for more than 10 years in grass clearing and is really a stubborn surface of grass leftover. One could say "glazed" as a green hard surface. Should a broken bevel gear be replaced and it would be nice to first clean around. The steel brush is the only trick to rub the aluminum shaft to shine. Would there be "gentler" ways to dissolve with a substance that would not corrode aluminum?
I advise to use a piece of wood (fir, spruce) to clean it. This way you will not damage the shaft at all
Hello, thanks for the video. I'm using a FS560 C-EM and I had the same problem, but I was upset when I find that the greasing hole does't go in the gear Chamber, it goes behind the upper bearing, filling the transmission bar! Why? How can I show you in picture?
The grease should also go into gear chamber, slowly. But I don't figure out how it goes on transmission bar, the bearing should act as a stopper. Maybe there is something wrong with the bearing. You should check that out first.
Heat the housing.. and it'll fall right out.. all bearings are press fit..
Do you have to take the second circlip off to take the out but shaft bearing ?
If I remember correctly, there are two large circlips, and you have to take out both of them.

good video...
So only the bearing was worn? I have same problem but was thinking the gears were damaged... I may just need the bearing.
Only the bearing was worn, there was no sign of damage on gears. The gears are very strong, I think they can rezist a lifetime if something unusual doesn't occure
We blow through these heads on FS90's. We shatter them and strip the gears. We try to save the busted heads, and rebuild them but still only get a few more hours out of them after a rebuild.
Me gusto tu vídeo pero no sé logra ver bien me gustaría verlos mejor gracias
Bună ziua ce mărime este rulmentul care l-ați schimbat.
va mulțumesc
So it's like a $2-5 repair? Thank you for all your help!
Depends of the quality of the replacement bearings your using aswell as the gear lube. They usually have 3 bearings in the head.
Can we use the kombi attachments to fs 55???
I was interested about that too, but Stihl representatives told me it isn't possible. Although, I think with a bit of ingenuity an adaptation can be done
@@UsualRepairs not for fs55.. not enought power. it works on the fs85 or more.
Melegítve!
Úgyse értik, padre. :-)
De az tragédia hogy nincs egy normális csapágycserés video az egész qurva youtubeon.
Any way to add a grease zert without damaging gears or bearings?
Some gear heads have a hole that allows adding grease. You can check for a mid size screw around the gear head, take it out and add grease. If your trimmer hasn't have one, like mine, you can try to add grease through shaft connection.
@@UsualRepairs
I have changed the new parts and then assembling stage. Is it too much when I fill all the free space in the bevel gear with grease? As much as it fits.
@@jota5579 Add grease as much to cover the gears. If there is too much, the excess should exist through main rod bearing.
@@bacilluscereus1299 You should use high speed grease. These gears are spinning at very high speeds
I watched another video, where the man just heated the head for about 30 seconds with a heat gun, and the bearing fell out????? Tried it myself, the worn out head was easy, but the good head, put up a fight, ( the housing had cracked where it goes onto the shaft tube, so I was just going to swap the guts over, ( it will be a spare, a new one here is only about $US10 )..
Lo ideal hubiera Sido lavar las piezas con gasolina para que quedarán bien limpias y ahí si cambiar las partes a remplazar
why grease a sealed bearing?????
There're three bearings in this unit. Two sealed, one non-sealed. That's the point.
Some naration would be nice.
Those aren’t safety wires. Their snap rings. Plus I would have removed the gears in reverse order
