GFK 600 and right to repair?

I got a GFK 600 router about 4 years ago, and have used it in a custom-built CNC. It's been ok for that, the lack of speed control isn't good, but it seemed robust. I've certainly gotten some good use out of it. A few days ago I noticed the router sounded different, and was hot to the touch around the collet. Hand turning the bit feels rough as well. I assume the bearing on the collet end got worn out, and I was hoping I could replace it. Obviously doing so comes with risks etc etc, but anyone building CNCs is aware of this.

Anyway, the GFK600 seems simple enough to open - there are three screws holding the metal neck to the main body, you can remove this, the neck slides of ... and then locks in place half way off the body. It won't slide further, or back into place. So, now it's permanently stuck in this halfway off position. There are no further screws, tabs, or things to interact with. Seems Bosch deliberately designed the router to not be serviceable, maybe in the name of user safety.

From a right-to-repair perspective, this is not great. Everything on my router is fine, except a bearing, which I would imagine is a part most likely to wear out with regular use. Not being able to replace a bearing on a tool is like being prevented from changing a battery on a phone. Sure, one could argue that opening a phone ruins water sealing, plus unauthorized batteries are a first risk etc, but it's still reasonable to be able to want to replace parts that see heavy wear, and one could definitely design something around safe replacement of worn parts.

I've been a loyal Bosch "blue" customer for years and have a workshop full of their tools, but this the first time I try to repair one, and I'm a bit disappointed. I'm also wondering if there are better options out there.

Update :

Thanks for the various links. Using them I was able to determine that the motor bushings were locking the motor inside the body. The bushings can be removed by removing the large plastic thread caps on the top end of the body, and then pulling out the copper-looking objects inside. I didn't want to remove these at first as they looked electronic, but they are actually both electronic and mechanical in nature.

The lower large bearing is not easy to remove, you're going to need a lot of violence / force to knock or squeeze it out of the metal case. I used a heavy vice with some wood standoffs, and the bearing didn't come out intact. Thankfully, it didn't need to, it's definitely cooked.

Also, the bearing listed in the official part list is discontinued. It looks the 6002RS bearing is a suitable substitute. I guess I'll know when my order arrives.

So I stand corrected, Bosch Pro seems to be pretty good for RTR, I take my initial comments back. You'll likely still need a teardown video or guide to help you, but once you're past that, it looks like you _can_ replace most parts.
