Jaw Set Removal - NPK M20S Instruction Manual

JAW SET INTERCHANGE
DETACHMENT OF THE JAW SET FROM THE MAIN FRAME
17. Support the jaw pivot pin (BJ) to
prevent its free fall upon total
removal, such as with a lifting strap
(t27) attached to a crane or lift truck.
18. Continue driving the assembly tube until it is centered in the jaw set.
19. Complete the removal of the jaw pivot pin by pulling it out or tapping on the
underside of the pin's head.
Avoid damaging the threads (177) when the pin is removed.

JAW SET REMOVAL

20. For easier removal of the jaw set
(DO) from the main frame (DN),
chain (t4) or strap the jaws together
to restrict their movement. Remove
the jaw set from the main frame with
a crane or other lifting device by
moving it horizontally out, not up or
down. For better movement control,
a second strap or chain can be used
to help level the jaw set.
