Anleitung Zusammenfassung
Feed clutch access covers removed. -68- V Qty .....1 .....1 .....1 3. Rotate the shroud washer so the cutout lines up with the shear pin head (Figure 127). Figure 127. Shroud washer/pin alignment. 4. Put on your safety goggles. 5. Using retaining ring pliers remove the retaining ring from its groove and place it in the rear most position away from the shroud washer (Figure 128). 6. Move the shroud washer away from the shear pin to the rear position so there is a gap to remove the shear pin (Figure 128). Figure 128. Shear pin access. G0670 16" x 40" High Precision EVS Lathe 7. Using a magnet, remove the shear pin head, then rotate the lathe spindle to line up the bore that has the rest of the shear pin inside, and use the magnet to remove the other half of the broken shear pin (Figure 129). 8. Using a blow gun tip inserted into the shear pin hole, blow out the hole with compressed air and apply a drop of oil in the hole. Figure 129. Aligned shear pin bores. 9. Insert the new shear pin into the bore (Figure 130). —If the pin does not freely slide into the bore, DO NOT hammer on the pin or you may permanently damage the shear mechanism and bore making it next to impossible to remove and install a new shear pin. Instead, take the time and carefully line up the two bores. You may file a slight chamfer on the end of the pin to assist in pin insertion. Figure 130. Pin installation.

With the pin completely seated in the bore and the head flush with the leadscrew shoulder, slide the shroud washer against the shoulder and rotate the washer 180° so the washer covers the head of the shear pin (Figure 131). Figure 131. Shroud washer positioning. 11. Using retaining ring pliers, return the retaining ring to its groove, and position the retaining ring ears over the shear pin head. If the shroud washer rotates and the pin access groove lines up with the pin, the snap ring ears will still prevent the shear pin from falling out (Figure 132). Figure 132. Retaining ring final installation. 12. Reinstall the access covers. V Gap Removal & Installation Your lathe has a gap section below the spindle that can be removed for turning large diameter parts. This gap was installed, then ground at the factory during lathe assembly for precise fit and alignment. Factors during the remaining assembly apply additional forces to the gap; therefore, replacing the gap to the original position will be very difficult. NOTICE We don't recommend removing the gap. Reinstallation to exact factory alignment is nearly impossible. The only option is to then leave the gap out. To remove the gap: 1. Using an 8mm hex wrench, remove the four cap screws (Figure 133) from the bottom of the gap. 2. Using a 6mm hex wrench, remove the two capscrews from the ends of the ways, and then with the 4mm hex wrench, remove the two bed set screws (Figure 133). 3. Using a 17mm wrench, tighten the two dowel pin jack nuts (Figure 133) until the pins are pulled free from the gap. 4. Tap the outside of the gap with a dead blow hammer to loosen, and remove the gap section. To reinstall the gap: 1. Using mineral spirits and a clean lint-free rag, clean the mating surfaces of the gap, bed, and ways. 2. Wipe a layer of light machine oil on all freshly cleaned surfaces. 3. Using a block of wood or dead-blow hammer, fully seat the gap in the lathe bed with the best possible alignment. 4. Back off the dowel pin jack nuts, and tap the dowel pins back into their respective holes until seated. This process will further help align the gap and bed mating surfaces. 5. Install all fasteners into position, and lightly snug them in place. 6. Study the shape of the gap and the orientation of the fasteners to determine which fasteners need to be tightened first, and in which sequence, so the gap will realign with the ways. 7. Using the hex wrenches and a dead-blow hammer or block of wood, alternately tighten the fasteners and tap the gap into alignment. Figure 133. Lathe gap. 8. Inspect the gap position 24-hours later to make sure the gap is still aligned. — If it has shifted slightly, use the hex-wrenches and dead-blow hammer or a block of wood again. Alternately loosen and tighten the fasteners at the shifted location, and adjust the gap into final alignment. -70- G0670 16" x 40" High Precision EVS Lathe SECTION 8: WIRING These pages are current at the time of printing.
