Replacing the drive belt (B10/B14/B14H)
CAUTION
Since a positional shift occurs after replacing the belt, return-to-origin must be per-
formed again and the point data re-specified. When removing the parts, check and
mark the part positions versus each other so you can correctly reassemble the parts
later.
1) Remove the end cover on the non-motor side and then remove the upper cover. (On robot
models having a long stroke, remove the upper cover by sliding it along the axis of robot
movement. This is required because the slider is fitted in the travel guide (U groove) inside the
upper cover.)
2) Remove the motor. (See the procedure in "4-5 Replacing the motor" in Chapter 4.) It is unnec-
essary to remove the motor if installed horizontally or downwards.
3) Remove the cover 1 shown in the photo.
4) Remove the eight bolts (4 bolts on each side) securing the belt stays and remove the belt stays
from the slider table.
