Adjusting Clamping Mechanism
The clamps are pre-set at the factory and should
not need any adjustment. However, if
adjustment is needed remove the stud (A, Fig.
23). Loosen the locking handle and slide the
headstock, tailstock or tool rest to the edge of
the bed and slightly turn the hex nut (B, Fig. 23).
Slide back into position and test the handle to
make sure it securely locks.
Changing the Belt and Bearings
Changing belt and bearings can be a difficult
task, and should be performed by a JET
authorized repair station. Remove headstock
and take into a repair station for servicing.
1. Place the belt in its highest speed range.
Do not change speeds while changing the
belt or bearings.
2. Remove the belt cover, and remove the belt
from the lower pulley, see Figure 24.
3. Loosen two set screws in the handwheel
enough to unthread handwheel (C, Fig. 24).
4. Loosen socket head cap screw enough to
unthread the clamping nut (D, Fig. 24).
5. Remove one e-ring (E, Fig. 24) from spindle.
6. Loosen two set screws in the right hand
pulley (F, Fig. 24).
7. Use a wood dowel, or aluminum stock to
knock spindle towards the tailstock. Use a
material that is softer than the spindle so
you do not mushroom end of spindle. Go
only far enough to remove right hand pulley
and belt from spindle, see Figure 25 when
changing the belt. Note: Mark key way on
the pulley for easy reference when
reassembling.
8. Now you can replace the belt or bearings.
There are three bearings #6, 9 and 43 that
can be seen in the “Headstock Assembly,”
page 24.
9. To reassemble reverse the procedure.
Note: Key way alignment is critical for
installment and proper operation. Do not
force the pulley. When reinstalling
clamping nut thread it on to the spindle until
its snug. Then back off slightly and tighten
the socket head cap screw.
