6.2.4 Replacing Bands
1. Follow the lockout/tagout procedure in place to ensure safety
2. Remove the side cover from the intended work area.
3. If band being replaced is on the outside groove/hub of the roller (shown as band number 2 in
Figure 7), the two rollers within the bracket symbols will need to be removed. Follow the roller
removal steps in the roller replacement procedure.
4. After the rollers have been removed, slide one of the rollers that was removed through band
number 1 of Figure 7.
5. After the roller is within band number 1, slide the new band onto the same roller on the groove
side of the roller (left side in Figure 7.
6. Use the new band to help guide the hex shaft into the hex hole.
This method is effective but requires a large amount of tension in the bands.
Because of this tension fingers can be pinched if not done carefully.
7. Once the groove side hex shaft (left side in Figure 7) is within the hex hole, insert the opposite
side hex shaft into the appropriate hex hole. Use the roller’s length as leverage to aid in this step.
As called out in the roller replacement procedure, use a putty knife or other flat surface tool to
protect the paint on the side frame.
8. After the first roller has successfully been re-installed, install the second roller.
9. Slide the roller through the old band (band number 3 of Figure 7), then slide the roller through the
new band.
10. Once the roller has both bands around it, guide the hex shaft into the hex hole.
11. Once the groove side hex shaft (left side in Figure 7) is within the hex hole, insert the opposite
side hex shaft into the appropriate hex hole. Use the roller’s length as leverage to aid in this step.
As called out in the roller replacement procedure, use a putty knife or other flat surface tool to
protect the paint on the side frame.
12. If the band being replaced is on the inside groove/hub of the roller as shown by band number 1 of
Figure 7, then remove the hex shafts opposite the groove/hub.
13. Roll the band being replaced down the length of the two rollers.
14. Roll the new band up the length of the two rollers.
