BLADE BOLT TORQUE
SPECIFICATIONS
Proper torque of the LaBounty shear blade bolts is
a crucial factor in extending the life of the shear and
blade components. Maintaining the proper torque
according to the specifi cations in this manual will
help prevent loosening of blades and possible dam-
age to the blade seats.
LaBounty shear blades can be rotated to utilize all
four blade edges (see
Figure 5-7
for the compo-
nents of a typical blade replacement kit). Blade bolts
and washers can typically be used for the life of the
accompanying blade set. Due to the critical nature
of these fasteners, Stanley LaBounty requires that
blade fasteners (bolts and washers) be replaced
with each set of new blades.
When using existing blade fasteners during blade
rotations, always inspect the hardware for any im-
perfections or damage and replace as necessary. If
a bolt has become elongated or a washer has spun,
it will be diffi cult or impossible to achieve proper
torque to secure the blade in the seat.
Proper torque values for blade bolts are listed below.
These values should only be used for blade bolts.
ASSEMBLY PROCEDURE
Your new Saber shear has a raised area on the Saber
Tip™ that fi ts into the Secondary Blade of the upper
jaw. This helps provide uniform support and load-
ing of blade seats when piercing items that do not
extend totally across the piercing tip.
FIGURE 5-7
Earlier model blades have a counter-bore and remov-
able dowels to do the same function as the updated
four-bolt tip design.
