If planning to exchange wear plates (3100-0), cheek plates, deflector plate (3500-0), and/or support bars (3200-0) at the same time, please proceed to the instructions for those parts before installing the new jaw plate. Replace the support bar screws if they are broken. Remove the support bar and clean it carefully. It’s important that the contact faces of the jaw are clean.

1. Clean the wear plate (3100-0), support bar (3200-0), and corners of the crushing chamber.
2. Position the hook of a mobile crane vertically above the new jaw plate (3300-1).
3. Hang the lifting tool (2) (provided with the crusher) on the hook of the mobile crane and attach the hook of the lifting tool to the lifting cavity (1) on the new jaw plate (3300-1).
4. Take up the slack in the lifting tackle. Be aware of the weight of the jaw plate. Handle the jaw plate with care. The tackle should now be tight but not lifting the jaw plate. Keep clear of hanging loads.
5. Carefully lift the jaw plate (3300-1) into the crushing chamber.
6. Place the jaw plate (3300-1) on the support bar (3200-0).
7. Adjust the jaw plate (3300-1) into its correct position.
8. Place a crow bar between the jaw plate (3300-1) and the deflector plate (moving jaw) (3500-0) or front frame end (stationary jaw).
9. Slacken off the lifting tackle.
10. Remove the hook of the lifting tool (2) from the lifting cavity (1).
