SHEAR JAW SET MAINTENANCE
PIERCING BLADES
1. Remove blades using an air-impact or breaker bar and
multiplier.
2. Remove dust and debris from blade seats; wipe down
with a rag and solvent.
3. Lightly file deformities from blade seat edges. Do not
sand or grind face of blade seats.
4. Install new, clean blades.
5. Snug lubricated blade bolts by hand to hold them in
place; push blades up-and-in to the upper and rear sur-
faces of the seats.
6. Torque bolts to 1/3 of the final torque value.
7. Check for firm contact against blade seats.
8. With a feeler gauge, confirm gap of .002” to .010” where
blades meet at piercing surface. A very narrow gap may
be confirmed by shining a flashlight from below the blades
and seeing light pass through.
If gap exceeds .010”, call the Genesis Service Department.
If no gap exists, remove blades, lightly grind facing sur-
faces, and repeat steps 5-8.
9. Torque bolts to 2/3 final value, and then to final value,
using a cross bolt pattern.
Piercing tip bolts must be lubricated and torqued as speci-
fied below. Correct clamping force is required to keep tips
from moving on their seats. Over-tightening can cause
bolt shanks to stretch, thus losing their clamping force.
Loose bolts will cause the seating areas to erode.
