Thread: Any VL175 Owners??

The bearings supply the aglingment of the shaft.

The main function of this collar is to provide the pre load adjustment to the bearings.

The 3 grubscrews lock the collar in position and maintain that adjustment.

The close tolerance of the collar in the housing provides the dust seal to the bearings.

Incorrect adjustment of the 3 grub screws can result in the collar touching the headstock housing. This makes a noise and is probably what you heard after making the adjustment.

Thats exactly whats wrong but i've tried i don't know how many times to adjust them and always have them rubbing. I just can't seem to get it right

When you had the original misadjustment and the lathe was making a noise, you may have got some metal transfer onto the collar and this interfered with the clearance.

Suggest you remove the spindle and check both the collar and the housing.

If this has happened it would be more likely there would be metal pick up onto the collar rather than the reverse. Check the collar for any raised burrs on the outside diameter.

Again I'll state the importance of the correct method of tightening the 3 grub screws. A small amount of tightening to each one in turn, rather than to tighten one fully followed by tightening the next one fully, ect.

Cheers
