12) Carefully pull the opposite
end of the original belt out
through the reversing unit
as you feed the spliced
ends of the old and new
belts into the other
reversing unit. Keep pulling
until the splice comes out
at the back of the second
reversing unit.
13) Remove the tape splice, and insert both ends of the belt into the coupling properly.
14) Insert both tension bolts into the coupling hardware, and take up most of the belt
slack. Align the single bolt (left side of coupling) to the adapter block, and tighten
securely.
15) Tighten the tension bolts to take up the remaining slack in the belt, or until the bolt
ends are protruding from the coupling nuts equally and by the same distance as
originally. Note: the new belt is probably slightly longer or shorter than the original;
you must tension the belt by “feel” if this is the case.
16) Repeat the procedure for the lower X-axis belt. Since the belts are a matched pair,
simply tension each belt coupling equally to achieve the same tension for both belts.
17) Re-tighten the torque rod coupling bolts securely, then replace the housing with the
appropriate hardware.
18) Replace the X-axis cable carrier bracket to the adapter plate, and the carrier chain to
the bracket.
19) Remove the four angle brackets from the top and bottom frame extrusions. Remove
all four T-nuts as well to avoid the possibility of jamming.
20) Power up the machine and make test cuts to verify proper operation.
