b.
Install 48T pulleys on the upper right (
B
pulley shaft) and the lower right pulley
shaft.
c.
Install the 15T pulley on the
B
pulley
shaft (upper right).
d.
Install the 20T pulley on the
C
pulley
shaft, then place the 120XL timing belt
between this pulley and the 48T pulley
on the lower right.
e.
Place the 140XL timing belt on the
upper left 16T and 48T pulley on the
B
pulley shaft.
f.
Install the 48T pulley on the
C
pulley
shaft, then place the 120XL timing belt
between this pulley and the 15T on the
B
pulley shaft.
7.
Apply upward and forward pressure to the
upper right and middle right pulleys (see
Figure 58) as you re-tighten the shaft hex
nuts you loosened in Step 3.
8.
Continue to apply pressure on the pulleys as
you re-tighten the thumb screw to tension
the timing belts.
Important:
Leave a slight amount of slack in
the timing belts when securing the pulleys.
Adjusting the tension too tightly will cause
excessive wear and stretching. Adjusting the
tension too loosely could cause the belt to
slip during operation.
9.
Close the end cover before re-connecting the
lathe to power.
