Installing Accelerators - MacDon R113 Operator's Manual

Installing Accelerators

1. Place a wooden block between two cutterbar discs to
prevent disc rotation while tightening blade bolts.
IMPORTANT:
Accelerators can operate in a clockwise or
counterclockwise direction. Verify the direction
of the disc before installing accelerators. If you
are unsure which direction the spindle rotates,
refer to
4.5.3 Cutterbar Spindles, page
2. Install lock nut (A), accelerator (B), blade holder (C)
and hex-socket bolt (D). Do NOT tighten at this time.
3. Install nut (A), flange bolt (B), and cutter blade (C)
onto disc.
4. Torque each nut to 92 ft·lbf (125 N·m).
WARNING
Ensure cutterbar is completely clear of foreign
objects. Foreign objects can be ejected with
considerable force when the machine is started and
may result in serious injury or machine damage.
5. Remove wooden block.
6. Close cutterbar doors (refer to
Doors, page 159).
