Adjusting Backlash V-Belt Replacement

Leadscrew backlash is the amount of motion the leadscrew rotates before the device begins to move. Leadscrews always have a certain amount of backlash that will increase with wear. Generally, 0.005"–0.010" of backlash is acceptable.

The backlash of the longitudinal and cross leadscrew can be adjusted by changing the gap in the leadscrew nuts (see Figures 63–64).

Use a 5mm hex wrench to tighten or loosen the cap screws on the leadscrew nuts shown in Figures 63–64, then test the amount of backlash by slowly rocking the handwheels back-and-forth.

If the belt is cracked, frayed, or shows signs of slipping and glazing you must replace it.
