JAW CONTACT AREAS

S, C, and G JAW CONTACT AREAS

In contact areas of jaws, hard facing (we3) may be added to increase the wear life of
these surfaces for hard facing instructions, see the "JAW and TOOTH REBUILD
PROCEDURE".
S JAW
C JAW
G JAW
K JAWS: Several surfaces of the K jaws have been hard-faced in contact areas. Hard
facing (we3) may be added to increase the wear life of these surfaces. The best time
to rebuild them is as soon as the hard face pattern is worn off. If the hard face pattern
is completely worn, the surfaces should be rebuilt and hard-faced such that they are
even with or slightly above the adjoining blades, see "HARDFACING K JAWS".
