Routine Service and Maintenance
Chain Master Link
If the trencher chain needs to be removed from the trencher, it can be broken at the Master
Link.
When the Master Link is removed, the chain could fall off the trencher frame. Keep your
hands and feet from underneath the chain to prevent injury.
To separate the Master Link:
1. Inspect the chain and locate the master link (Item 1,
Figure 4–24
), which will have a remov-
able pivot pin and cotter pin instead of two bolts.
2. Support the trencher chain from underneath the trencher frame.
3. Remove the cotter pin (Item 2,
Figure 4–24
) from the pivot pin (Item 3,
Figure 4–24
) and
then remove the pivot pin.
4. Remove the spacer tube (Item 4,
Figure 4–24
) from the chain links (Item 5,
Figure 4–24
).
5. Using an appropriate lifting device, remove the trencher chain from the trencher frame.
6. Replace the trencher chain and reassemble the master link by reversing Steps 1-5.
