Instructions on the adjustment procedures

The purpose of this section is to provide procedures for the major adjustments required on the feeder breaker.

It is essential that adjustments be made periodically to the conveyor chain and crawler tracks, as otherwise damage can be caused to other parts of the machine or to the assembly itself. Inspect the adjustments at regular intervals.

In addition to the mechanical adjustments, there are hydraulic settings and electrical timers that may require adjustment.

Conveyor chain tension

With the machine off, check the conveyor chain tension at the head shaft end (Fig. 61). When the conveyor chain is properly tensioned, there will be approximately 2 inches (50 mm) of droop on the bottom side of the head shaft sprockets. With the machine running, visually inspect tail shaft to ensure shaft is turning and conveyor chain is engaging the tail shaft sprockets properly.
