3.4 Main Frame Seat Liner and Fulcrum Bar
3.4.1 General Information
Periodically, the main frame seat liner and fulcrum
bar should be inspected for wear. Due to
irregularity in feed to a Crusher and the slight
rubbing action between the adjustment ring and
main frame seat liner, there is a certain amount of
wear.
Should there be an excessive amount of adjustment
ring movement, this wear could be increased. Refer
to Figure 3-8.
The fulcrum bar is very important as it permits the
adjustment ring to tilt and recenter properly when
the ring raises due to a piece of tramp iron passing
through the crushing cavity.
