Thread: Anybody replaced bearings in a Bosch GOF1600CE???

It looks to be threaded, perhaps a left hand thread?

Already tried turning it both directions with as much force as I was game - nothing to get hold of to turn against is the main problem there . I had the shaft held in the lathe chuck with a piece of PVC pipe to protect the thread while I tried turning the ring but figured if it was that easy, it should have come undone while fitting/removing a router bit at some point.

You've probably looked at the replies at the bottom of this YT video, but just in case - Bosch GOF 1600 CE Shaft Collet Problem - YouTube

Casting around online it would appear that you're not the first to have this problem. Have a look at this YT video at about the 4:30 mark where the guy undoes that collar nut by hand - Como concertar tupia Bosch GOF1600 - YouTube

Slow the last link down to .25 and you can see what is happening.

Thanks heaps for that . At least I know how it's secured now so I'll give it another shot treating it as a normal right hand thread and see how we go. That video probably came up in my searches but I rarely look at the non-English ones - that'll teach me!!!

Well that was an interesting exercise!!! Tried undoing the spindle-nut by heavily tightening a bit in the collet which turns the nut in the correct direction but it still needed a jolt from a pin punch to get it moving - the nut spun off easily after a really good tap. The small bearing on the other end proved to be a problem to remove but I got there eventually. SO GLAD I didn't go ahead and cut the spindle-nut off (Plan B) as the main bearing turns out to be only a slip fit on the shaft and the system requires the spindle-nut to lock it all together. Only found this out after reassembling the whole thing without the nut so I could just use a spanner to change bits. The shaft was spinning inside the bearing so I pulled it all apart AGAIN! and locked the nut on - hope it's tight enough or it's going to come undone the first time I install a bit and I'll have to do it all again .
Thanks again for the help guys
