Divert switch repair, replacement, and service
1.
See Figure 21 and Figure 22 in Appendix 3 for exploded view and part numbers
2.
Recommended to swap the complete switch with a spare, so the switch can be rebuilt without
keeping the sorter down for an extended period.
3.
The divert switch assembly hangs from the sorter frame with four carriage bolts (accessed from
underneath the switch).
4.
See Figure 19 and Figure 20 in Appendix 3 for details on installing and removing divert switches.
5.
When swapping out the switch, ensure that the new switch is aligned with the pin guide and that
the shoe pins are correctly positioned inside the pin channel of the switch.
Running the sorter with a switch missing or misaligned can cause damage to
the slats, shoes, and pin guide.
7.3
Chain Adjustment
All chains should be kept well lubricated. If slack develops in the chain, adjustments should be made by
qualified maintenance personnel.
1.
Periodically check the chain for excessive wear. See the Diamond Chain Roller Chain Wear Gauge
Instructions for a detailed procedure.
a.
The maximum acceptable elongation is 1.5%. The chain will need to be replaced if it has
elongated more than 1.5%.
Rapid or uneven chain wear is a sign of insufficient lubrication.
2.
As the chain wears, the chain will have to be cut and re-spliced if the total loop length becomes too
long (as indicated by an alert from the catenary chain sensor).
a.
See the Diamond Series Product Catalog for instructions on splicing chain
b.
Grind the peened over ends of the chain pins flush with the link plate before pressing them out,
else the chain bushings will be damaged.
c.
When reducing the chain length to compensate for wear, it is recommended to break the chain
at the short section that was cut to length during installation, instead of taking a link out of a full
section.
d.
Always put chain connecting links directly across from each other.
e.
Chain can only be cut and spliced in full slat increments (every four pitches).
