TROUBLESHOOTING
The objective is to locate and isolate the problem.
NOISE IN THE HEADSTOCK/GEARBOX:
Note: 85% of noise normally comes from the output shaft pulley.
1. Run lathe with all controls in neutral to see if the problem is in the spindle.
a. If the problem is in the spindle and the finish is good, the source is most
likely in the rear bearing (Part#65). However is the finish is poor, the
problem could be the front bearings are either loose or damaged.
b. If the problem is not in the spindle, continue by engaging one control at a
time until the problem is found.
(Figure 1)
c. If the problem is not in the headstock. Before you continue to the gearbox,
check the change gears located on the back of the headstock for proper
backlash and alignment.
(Figure 2) If these gears are found to be in good
working order, perform the same sequence as above on the gearbox.
(engage on control at a time until the problem is located.)
(Figure 3)
d. Once you determine the problem is either in the gearbox or the headstock,
that part of the machine must be opened up to the inspect for possible worn
or broken parts.
2.
If the gearbox is in order and the feed or leadscrws are not turning check the
shear pins. (There are two shear pins on each shaft).
