Jet Tools JWL-1642EVS-2 Adjusting the Clamping Mechanism, Changing the Belt and Bearings

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. 24). 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. 24). Slide back into position and test the handle to make sure it securely locks.

Changing the Belt and Bearings

Changing the belt and bearings can be a difficult task, and should be performed by a JET authorized repair station. Remove the headstock and take it into a repair station for servicing.

1.Disconnect the machine from the power source!

2.Loosen the locking handle (C, Fig. 25), and lift up on the tensioning handle (D, Fig. 25) to remove tension from the poly v-belt.

3.Open the door (E, Fig. 25), and remove the belt (F, Fig. 25) from the lower pulley.

4.Loosen the two setscrews in the handwheel (G, Fig. 25) and remove.

5.Loosen the socket head cap screw enough to unthread the clamping nut (H, Fig. 25).

6.Loosen the two setscrews in the right hand pulley (I, Fig. 25).

7.Loosen the setscrew in the collar (J, Fig. 26)

8.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. Only go far enough to remove the belt from the spindle; see Figure 26.

9.Now you can replace the belt or bearings. There are two bearings, #5 and 10, that can be seen in “Headstock Assembly” on page 24.

10.To reassemble, reverse the procedure. Note: When reinstalling the clamping nut, thread it onto the spindle until its snug. Then back it off slightly and tighten the socket head cap screw.
