Re-Assembly of the Belt
Sit the new belt on the pulley and place back into
headstock.
When re-inserting the spindle, make sure that the key
on the spindle lines up with the keyway to avoid any
damage.
Line up the pulley back in its original position and re-
tighten the grub screw in the middle pulley.
Screw the handbrake wheel back on until there is no axial
play in the spindle and tighten the grub screws.
Hook belt around the motor pulley and tighten the belt
adjustment. Check the belt deflection to ensure the
correct tension. (see page 17)
Once assembled replace all covers, disengage the
indexing pin and turn spindle by the hand wheel to
check for hard spots.
Turn the machine on at the mains switch and run the
machine at moderate Rpm (approx 1500 rpm) for five
minutes to check the operation of the machine.
If the pulley housing gets hotter than luke warm to
touch after 5 minutes of operation then stop the
machine, loosen the handwheel grub screws and
unscrew the handbrake wheel approx 2 to 5 degrees
then re-tighten the grub screws.

Servicing the Tailstock
Removing the Quill on the Tailstock:
Lock the tailstock onto the bed using the locking lever.
Turn the hand wheel so that 20-25mm of the quill is
protruding from the front of the tailstock.
Loosen the grub screws on the handle two or three
revolutions.
Pull off the handwheel.
Loosen the nuts on both sides of the tailstock, then
remove the grubscrews.
The quill can now be removed from the tailstock
The quill can now be cleaned along with the inside of
the tailstock.
Note.
Never use sandpaper to clean the quill and take
care not to remove the
key piece
at the end of the
locking lever while cleaning.
All mobile parts should now be greased with a high
quality grease or graphite grease before re-assembly.
Re-Assembling the Quill on the Tailstock:
The quill should be re-placed from the back of the
tailstock making sure that it is horizontal to the bore.
Push the quill back into place and align the keyway into
the key piece.
Reallign the drill marks in the tailstock bush to the grub
screw holes and retighten the grub screws equally.
Then retighten both nuts.
Replace the hand wheel and tighten the grub screws.
Turn the hand wheel. If it does not run smoothly (i.e.
slight gripping or scraping) several light taps on the
hand wheel with rubber hammer will bring the quill into
alignment.
The free play of the hand wheel should be no more
than 10 degrees.
