- Carefully knock the spindle, towards the tail-stock. Use
a block of wood against the spindle end to prevent any
damage when it is hit with a mallet/hammer. The spindle
pulley, now loose, will slide along the spindle.
- Remove the old belt, if present, and install the new belt
over the spindle pulley. Return the pulley back onto the
spindle, and re-install the spindle back into the headstock
casting. As in step 7, carefully knock the spindle and
bearings back into place with a block of wood and mallet.
- Secure the spindle pulley in place on the spindle with the
set screw(s). Make sure that the set screws engage back
onto the flat section on the spindle to eliminate slippage.
- Re-assemble the remaining headstock parts by reversing
the procedure previously described.
There may be two (2) set screws in the threaded hole, one on top of the other. If assem-bled in this manner, this
stacking prevents the set screws from loosening during use.

WARNING
5.6 CHANGING THE BEARINGS
5.7 TYPICAL LATHE TURNING OPERATIONS
If the bearings ever need to be changed, the whole spindle shaft needs to be shifted right, out of the headstock, towards
the tailstock. Then the bearings can be removed from the headstock casting. With the new bearings in place, the spindle
shaft assem-bly can be re-installed, so turning can be resumed.
- Unplug the lathe from the power source.
- Remove any accessories from the spindle -spur center, pen mandrel, chuck, faceplate, etc..
- Follow the steps 2-7 described in CHANGING THE DRIVE BELT on page 13, to remove the hand wheel and loosen
the spindle pulley from the spindle. The drive belt will be loose on the spindle.
- Carefully knock out the spindle towards the tailstock. Use a block of wood or big dowel against the spindle end to
prevent any damage when it is hit with a mallet/hammer. The spindle pulley, now loose, will slide along the spindle.
- Carefully pull out, or knock out the old bear-ings. Use a mallet/hammer with a block of wood against the bearings to
prevent any damage to the machine. Do not remove the large retaining C-Clips from the inside of the castings. These
clips properly position the bearings when in place.
- Shows the lathe set up for a typical spindle turning
operation. Note: Position the tool rest as close to the work
piece as possible. It should be 1/8” above the center line
of the work piece. FIG. 5.6
- For turning plates, bowls and small turnings, a chuck or
faceplates can be used (available separately). The work
piece should be “rough cut” as close as possible to the
finished round shape before mounting. FIG.5.7
.
- Install the two new Bearings in the front and in the rear
holes of the headstock.
- Re-assemble the lathe parts by reversing the procedure
previously described.
