Removing the Y-axis arm upper cover (R6YXP700 to
R6YXP1000)
Proceed as follows while referring to Fig. 4-3.
1) Turn off the controller power.
2) Place a sign indicating “work in progress”, to keep others from operating
the controller switch.
3) Remove the two side covers and rear cover 1 of the robot base (pedestal).
4) Remove the FG wire round terminals (2 pcs) from the machine harness.
5) Remove the user air tubes 1 to 3 from their couplings.
The air tube colors match the coupling colors.
6) Remove the Y-axis and R-axis joint air purge tubes from their couplings.
Place marks so the air tubes can later be connected back to their original
positions.
7) Remove the YM, ZM, RM, YP, ZP, RP, ZBK, FG and IO connectors.
8) Cut the Insulock tie straps that are clamping the machine harness.
9) Loosen the flexible couplings and extract from the shaft.
10) Remove the machine harness from the shaft hole.
Handle with care not to damage the connector, wiring, and tubing.
11) Loosen the Y-axis arm flexible coupling and extract from the shaft.
12) Pull the flexible coupling in the direction shown by the arrow, and move it
all the way to the edge of the wiring connector on the robot base side.
13) Remove the bolts that secure the bearing holder on the top of the Y-axis
cover. Insert a flat-blade screwdriver between the bearing holder and the
Y-axis arm upper block, to pull out the shaft along with the bearing. There
are O-rings fitted into the top of the block and also the inner side of the
block. Fit these O-rings back into their original positions when
reassembling.
14) Remove the bolts that secure the Y-axis arm upper block and remove the
block.
