6.2.3 Replacing Rollers
For motor driven rollers (MDRs):
1. Follow the lockout/tagout procedure in place to ensure safety.
2. Remove the side cover from the intended work area.
3. Loosen the MDR nut located on the cable side of the roller.
4. Pull the MDR bracket away from the frame. Refer to Figure 4.
5. Apply pressure on the end of the hex shaft opposite the cable using a small diameter punch or
similar tool until the shaft clears the frame. Be careful NOT to apply a side load to the hex shaft.
Although the side frame pictured in Figure 5 is that of a straight conveyor bed, the method used
for removal of MDRs is the same as that of a curved conveyor bed.
6. Provide upward force on the roller body until the hex is sitting above the side frame. Although the
side frame and rollers pictured in Figure 5 are that of a straight conveyor bed, the method used
for removal of MDRs is the same as that of a curved conveyor bed. (A putty knife or other flat
surface tool is recommended to be placed between the hex shaft and the inside of the frame. This
will help protect the paint on the side frame.)
