Fitting the Moving Jaw
1. Inspect the backing plate and remove any burrs
as necessary to create a smooth surface or
renew the plate.
2. Renew any wedge locking nuts and bolts if they
are damaged or bolt is bent.
3. The jaw can be turned when half worn, the lower
worn part being re-󰘰tted at the top.
4. When turning over and re-using a jaw, clean the
back face and remove any burrs
5. Check the centre jaw location for wear. The
nominal width of the location lug on the jaw
holder when new is 73 to 74mm (2.9in) and
if the wear is more than 5mm (0.2in), the
sides will require building up with hard weld
and shaping to make sure it locates the jaw
centrally.
7. Fit suitable lifting shackles to the upper corners
of the jaw.
8. Fix suitable lifting equipment to the shackles
and support the weight using suitable lifting
equipment.
6. If welding is required, refer to any welding
notices on plant and in servicing safety and
precautions.
