Syil x3 Quill Runout

[Kevin Moore]

Hello Everyone,

I just purchased a Syil Super x3. Machine works great except, I have excessive runout on the quill. Has anyone out there, had this problem, and if so, what was your remedy? I took the top off, and pulled the pulley off, to adjust the locknut, nut on top, but i don't have a spanner wrench to remove them. Anyone know what size spanner wrench, or another way to remove the nuts. Appreciate any advise I can get.


Thanks,

Kevin

Well I am assuming what you mean by Quill run out is slop in the spindle bearings? Anyway you can remove the spanner nuts with a large flat head screw driver and a dead blow hammer, or a hard hammer if you do not care about the screwdriver.

When I first got my machine I dropped the spindle out and cleaned all of the bearings, re-paced, and put it back together. As another note, I had a race on the trust bearing fail and I replaced it with a higher quality one. Now it runs better than ever.

Hi,

Thanks for the advise. I will try the hammer and screwdriver technique.

Thanks,

see other posts on this on some x3's you cannot pre-load the bearings due to the spindle being oversize about 0.1mm thus the bearing wont go down the shaft
when you strip it look for this in the top bearing

I'm going to need to replace the spindle bearing on my Syil SX3 in the near future. Can anyone post a writeup on how to do this and what the bearing models are. Richard gave me a quick run through on the phone but I couldn't take notes fast enough and a picture is worth a 1000 words. He mentioned that the head would have to come off to have the new bearings pressed in and out. That seems fairly complicated since all of the electronics would have to be disconnected as well.

Thanks,

Thackman,

I've read the similar posts below and the one from Old Megawatts was the most helpfull. I could probably get the head disassembled but I'm not sure of the bearing removal and reinstallation process (pressing, packing, preload, etc). And once I get it apart I'm not sure how to determine if I need new bearings or to just clean up and reinstall the ones that are in it.

Richard from Syil recommened taking the head to someone with an arbor press to swap out the bearings. I've seen a kit on www.littlemachineshop.com to press out the bearings. It's just a set of tubes and spacers but they said they will not work on an SX3.

I wish that Syil would produce a few "how to" documents like ArcEuroTrade did. It seems like everyone has to do the same mods to their mills: cleaning up the ways, spindle bearings, shimming the column, etc. Maybe even a few examples of ballpark speeds and feeds for various tasks like Tormach has on their site.
