From the parts view in the manual, it looks like you’ll need to start by removing the handwheel from the end of the spindle by removing two screws locking it on. Then you’ll need to remove two snap rings from the spindle and the setscrew from the pulley. Then it looks like you should be able to push the spindle out the front. Then drive the bearings out from inside the headstock. I can’t tell for sure from the manual how/where the bearings seat but it should be pretty evident once you get that far.

You mean this lathe?

Looking at exploded parts list, How did you change belt without exposing the main shaft and bearings?

Once the shaft is separated from housing, bearings are simple matter to remove with bearing splitter/puller, and install with some PVC or copper pipe that slips over the shaft. If you need video support for changing bearings, search for bearing replacement on a induction motor. The lathe shaft would be similar, once you remove any retaining rings or set screws. If set screws have left marks on shaft, use a file to clean up the shaft so bearing can push past with interference.

Best Luck.

Karda, Are you certain you have bad bearings? You say they were fine until you changed the belt… Also that the noise is not constant… Before tearing down or condemning the bearings, test the headstock spindle for smooth rotation without the belt. Also check for axial movement by pushing the shaft left and right. Smooth rotation and no movement indicates to me that the new belt is at fault. My small Rikon lathe acted the same way… Thought I had bad bearings, but it was simply the belt… Not all belts are the same quality!

Don’t know what belt you used, but cheap belts are crap. Get a Gates, Conti, D&D etc. NO Chinese belts.

I’d wager the bearings that are sold with that lathe are far below average.
Good bearings in a lathe are important

i checked the spindle, know play in the spindle, everything is smooth with and without the belt. I got replacement belt for the lathe that wouldn’t fit. It went on but I had to force the belt from pully to pully if I put that on would it stretch to fit, this is a good quality belt its a D&D syncro power240J
