<Replacing the timing belt T: KE-2080R>
After the timing belt T has been replaced, it is absolutely necessary to re-input the MS parameters
related to the Z-axis home. (For details of input items, see section 2-9.)
(1) Detach the T-sensor dog c.
(2) Loosen the stop screws (2 pcs.) of the
spline pulley d.
(3) Detach the bearing base L e.
(4) Detach the spline shaft from the coupling.
(5) Pull out the spline housing assembly f
downward while detaching the spline
pulley. Additionally, pull out the spline
shaft upward.
(6) Replace the timing belt T.
(7) Reassemble the components in the
reverse order of disassembly.
When the bearing base L is secured, make sure that the shaft is rotated smoothly.
Make sure that the spline pulley and T-sensor dog do not have any play.
When inserting the spline shaft into the coupling, secure the spline shaft with it kept
pushed-in.
Adjust the belt tension following section 2-2-5.
