Y-Bearings

[Digitalwoodshop]

The 2 inner bearings come out each face side as there is a LIP inside.

Don't forget about that U shaped frame.....

And more than once I have found a FROZEN Roller Rail Bearing....

Thank everyone, I think i'm going to order a new one, I think this is out of my range to fix, it will probably be much easier to just replace it
Thanks again

Did you try and mount the Y motor pack higher in the slots? I really think that could be the problem. (With the Y motor pack out, you might see where the gear has worn through the black paint at the bottom of the slot.)

yes I tried it and still had the same problem

Thanks for the reply. Too bad we could not get this one figured out.

I'm late to the party but I almost think you set the tension a bit too tight when you put the Y pack back together. Where the cog actually meshes with the motor gear. If you set it real close when you put it back together then when you set the overall Y tension it's way too tight too move. Just a thought.

Anyone have the Y bearing size for the larger bearing and a good source. I have the smaller bearing just need the larger bearing that's in the newer y motor gearbox. Thanks

Why would you need the large bearing? If you have the new gearbox with the bigger bearing, the 250 hour bearing replacement should not be required. The bearings really should last much longer.

I made my own gearboxes with larger bearings and do not ever plan to replace them.

He doesn't have the new gearbox. He wants to replace the bearing in his old one, but use a larger bearing.

I dont know a size or source for those either.

I thought he had the newer gearbox. It would have the original small bearing in the rear and the larger bearing in the front I think. (There was no room in the rear for a larger bearing.)
