Adjusting or Replacing Rotor Knives

The rotor knives and bed knives are very sharp wear heavy gloves to avoid injury.

Use the rotor-locating pin to lock the rotor in the position that is least likely to cause injury as you work. The pin keeps the rotor from turning.

If the rotor knives and the bed knives are to be removed, remove the rotor knives first {and replace them last) to reduce the chance of injury.

LOCK THE ROTOR

Position the rotor so that a blade is at top dead center. Insert the rotor-locking pin into the hole in the right side bearing housing.

Apply light pressure against the pin while turning the rotor toward you approximately 10 degrees. The pin will drop into the hole when it is properly aligned.

The pin locks the rotor in place until the pin is removed.

REMOVE THE MOUNTING SCREWS

Loosen the rotor knife screws with a 30 mm socket mounted on a breaker bar (These screws are tightened to a torque of 472 ft lbs (640 Nm) so make sure you have the proper breaker bar (a four foot long (1.2 m) bar with a 3/4 inch (19

mm)drive is suggested. Make sure you have solid footing while you apply the breaking force.

Remove the mounting screws from the right rotor knife with a suitable socket wrench.

REMOVE THE ROTOR KNIVES

Lift the right knife off from the rotor and repeat the process with the left rotor knife.

Remove the rotor-locating pin, turn the rotor to bring the next knives into position for removal, insert the locating pin to hold the rotor in this position. Repeat the process for the remaining knives.
