Wear Parts - Replacing Jaws
11. Check the centre jaw location for wear. The
nominal width of the location when new is
270mm (10.6in) 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.
13. Check the wedges for wear on the contacting
surfaces and remove any burrs as necessary.
14. Repair or renew the wedges if the wear is more
than 5mm (0.2in).
15. Renew the wedge locking nut and bolt if they
are damaged or bolt is bent.
Fitting the Fixed Jaw
10. Inspect the backing plate and remove any
burrs as necessary to create a smooth surface
or renew the plate.
12. If welding is required, refer to any welding
notices on plant and in servicing safety and
precautions.
16. The jaw can be turned when half worn, the
lower worn part being re-tted at the top.
17. When turning over and re using a jaw, clean
the back face and remove any burrs.
