blade stays in position.
6. Apply good grade of bearing grease to clevis or yoke
in center blade where it rides on the eccentric bearing
assembly. Insert rear cap screw into shear housing but
do not completely tighten.
nOTE: Change the side knives after they show a width wear
pattern of 50%. Swap the knives left to right and use them
until the patterns meet. When the patterns meet, invert the
left and right side knives and use them until they show a
width wear pattern of 50%. They can then be swapped from
left to right until you use all 4 sides of the blades. Never
exceed 10000 feet of cutting on a set of side knives. The tool
will continue to cut after these landmarks are reached, but
the power unit will become overloaded.
Installing the Shear Head Assembly
(Fig. D)
1. To install shear head assembly
make sure all cap screws
complete turns.
2. Place shear head onto unit and alternately tighten cap
screws snugly to lock head assembly in place. It may be
necessary to gently tap the shear head into place if it
does not readily slip onto the nose of the power unit.
3. Tighten all three cap screws to 45–50 in‑lbs.
(5.08‑5.64 Nm). Failure to tighten the cap screws
properly can cause the cap screws to break.
