Hi! I've installed an Belt Drive upgrade kit on my mini mill some years ago.

But when installing it, I didn't remove the spindle completely from it's casing, so I removed the plastic gears but not the spindle gear. When I run my mill on higher speeds, that last gear sometimes makes noise.

And I want to replace the original bearings to angular contact ones. So I want to dissassemble the head again to remove the spindle, that remaining gear, and change bearings.

I've seen some how to's on how to remove the spindle and bearings on a stock X2 mill, before the belt drive kit was assembled. But I don't know how to pull that large pulley from the spindle. Can anyone give me a hint, or share some pics?

These two pics show how the kit is assembled in different views. Nowadays I removed all the fine feed and other stuff because it's being converted to cnc.



Thanks in advace.
