Adjusting the 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 the two setscrews in the handwheel enough to unthread the handwheel (C, Fig. 24).

4.Loosen the 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 the two setscrews in the right hand pulley (F, Fig. 24).

7.Use a wood dowel, or aluminum stock to knock the spindle towards the tailstock. Use a material that is softer than the spindle so you do not mushroom the end of the spindle. Go only far enough to remove the right hand pulley and belt from spindle, see Figure 25 when changing the belt. Note: Mark the 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.
