9-6 Rotor Knife Installation

1.Carefully lock the rotor with the locking pin to prevent it from turning.

2.Re-install the rotor knives onto the rotor. Do not torque the hex head rotor knife bolts fully at this point -- snug them down only.

CAUTION!

New or resharpened knives should be handled with extreme care. It is suggested that the sharp cutting edge be covered with tape to prevent damage to the knives or injury to personnel during installation.

3.Check that the heel of the rotor knife is tight up against the knife seat. Utilizing a .0015” feeler gauge, try to insert it between the heel of the knife and the knife seat at both ends and across the rotor knife. If the feeler gauge will not go down between the heel of the knife and the knife seat, the knife is installed correctly.

4.Torque down the rotor bolts. Start from the center of the knife and torque down the bolts equally, working towards the ends of the knife. Refer to Section 9-11 for the correct torque values based upon bolt sizes and thread pitch. After the bolts on each knife have been fully torqued, re-check with a .0015” feeler gauge between the knife and seat. Use the same procedure on all remaining rotor knives.

9-7 Bed Knife Sharpening

Each bed knife is provided with two (2) cutting edges. When the exposed edges become blunt, the knives can be turned over and repositioned to present the new cutting edges.

It is not necessary to grind bed knives to the closely matched tolerance of the rotor knives and as with the rotor knives small nicks in the cutting edges will not seriously affect knife cutting efficiency. Bed knives smaller than the minimum dimension shown must be replaced along with their fasteners.
