Resumen del manual
When the dial indicator needle stops moving, there will be no spindle end-play and no bearing preload. it is essential that you find this point without tightening the spindle nut further and preloading the bearings. if you think you may have gone past the zero end-play point, take the time to unload the bearings as instructed in Step 8, then retighten the spindle nut until you know you have reached the correct setting. Tip: Since it takes great effort to properly turn the spindle nut, you may find it difficult to know if you have gone past the zero end-play point or not. It is easiest to have someone watch the dial while you tighten the spindle nut. -63 Model g0554z (Mfg 01/09+) 13. When you are confident that you have adjusted the spindle nut so that there is no spindle end-play or preload, tighten the spindle nut an additional 9.16" turn clockwise to introduce the correct amount of spindle bearing preload, which is 0.003" (see Figure 98). Tip: Scribe marks on the spindle nut and the head casting to aid in turning the spindle nut 9.16". 9/16" SpindleNut Figure 98. turning the spindle nut 9.16". 14. re-install the three cap screws into the spindle nut, then prepare the lathe for operation by re-assembling all of the lathe parts. Note: Drain the headstock oil before replacing the cover and remove any debris from the inside of the headstock. Use a good quality silicone sealant when re-installing the headstock cover, then refill it with lubricant 15. install the chuck and tighten the jaws into the center, set the spindle to a medium speed, then connect the lathe to power and let it run for approximately 20 minutes. 16. turn the spindle OFF, let it come to a complete stop, then check the temperature of the spindle. —if the spindle is slightly warm to the touch, you have the correct spindle bearing preload. —if the spindle is hotter than you can comfortably keep your hand on, the preload is too tight and you must repeat this spindle bearing preload procedure. When repeating the procedure, rotate the spanner nut a 1.16" less during Step 13. -64 Gap Removal the Model g0554z comes equipped with a gap section below the spindle that can be removed for turning large diameter parts or when using a large diameter faceplate. the gap is installed, then ground at the factory during lathe assembly for precise fit and alignment. Factors during the remaining assembly and subsequent transport of the machine apply additional forces to the gap; therefore, replacing the gap to the original position will be very difficult once you remove it. if you choose to remove the gap, we do not recommend attempting to replace it. Tools Needed Qty Wrench 14mm ................................................... 1 hex Wrench 8mm.............................................. 1 dead Blow hammer .......................................... 1 To remove the gap: 1. Back up the preload set screw to release the locking tension on the gap (see Figure 99). Figure 99. lathe gap. preload set screw taper pins 2. remove the four cap screws that secure the gap. 3. tighten the hex nuts on the taper pins until the pins release from the gap, then remove the pins. 4. tap the outside of the gap with a dead blow hammer to loosen it, then remove the gap section.
