Grizzly G3358 owner manual Gibs, To adjust the Y-axis leadscrew

Leadscrew Backlash
When you turn the handwheels to adjust the posi- tion of the table, you will notice slight play (back- lash) in the handwheel before the table begins to move. If this play is greater than 0.008" (measured with the dial at the base of each handwheel), then you will need to adjust the leadscrews.
These adjusters may require you to fabricate extensions for your hex wrenches. Make adjust- ments in small increments. Over-tightening to attempt to reduce backlash to less than 0.003" is impractical and will add unnecessary wear to both the leadscrews and the adjusters.
To adjust the X-axis leadscrew:
1. Locate the X-axis leadscrew adjuster under the middle of the table. The head on the adjustment screw faces to the right (Figure 43).

3. Test the adjustment by turning one of the side handwheels. You should detect less than 0.008" of play.

To adjust the Y-axis leadscrew:

1.Access the underside of the base through the hole in the bench under the base.

2.Locate the adjuster midway along the leadscrew, inside the base.

3.Tighten the set screw on the adjuster.

4.Test the adjustment by turning the front handwheel. You should detect between 0.002" and 0.008" of play.

gibs

The gibs are pre-adjusted at the factory but due to storage, break-in, and usage, may require adjustment. If movement seems too tight at first, make sure that all waxy rust preventative coating is removed from the ways, lubricate them with oil, and work the table back-and-forth several times until the movement is loosened.

The gibs are adjusted by turning the large slotted screwheads in the front and right side of the table base until you feel a slight drag when you turn the handwheels. The screw at the front of the machine affects movement from front to back. The screw under the right side of the table affects longitudi- nal movement. You can loosen the screws if your table movement seems excessively stiff.
