15.9.1 Ledger Knife Spacer Tool
The Ledger Knife Spacer Tool is located on the lower
rotor housing.
As the blade wears, it can be rotated or flipped to use
a fresh corner. If the blade is moved, it must have its
clearance settings adjusted to maintain its shearing
efficiency.
The best way to ensure you have the correct clearance
is to use the Wallenstein Ledger Adjusting Tool. It is the
correct thickness to set the recommended clearance
between the rotor and stationary blades.
IMPORTANT! The clearance should be set
to 1/32–1/16" (.76–1.52 mm) for optimum
performance.
Depending on the chipper model, there may or may not
be adjusting bolts along with mounting nuts and bolts
to secure the ledger blade. Adjusting the ledger blade
is the same in either case.

).
1.
Remove the bolt that secures the upper rotor
housing, and carefully open the rotor housing.
2.
Carefully move the rotor so the a rotor blade
overlaps the ledger blade.
3.
Loosen the fasteners and / or adjusters and move
the ledger away from the rotor blade.
4.
Insert the gauge between the ledger blade and
rotor blade
5.
Move the ledger blade in towards the rotor blade.
6.
Ensure you move the ledger evenly, so the entire
edge of the ledger is in contact with the gauge.
7.
Hand tighten the fasteners, the gauge should drag
slightly between the blades
8.
With the gauge in place:
•
Tighten adjuster nuts first (if equipped).
• Tighten ledger blade bolts.
•
Tighten all fasteners as specified in the torque
chart.
9.
Check that the gauge still drags slightly when you
remove it.
Ledger blade is now correctly adjusted and is ready for
service.
It is recommended to occasionally check the blade
clearance per your chippers maintenance schedule.
NOTE: Depending on the model, the ledger blade
may have 3 or 4 mounting holes. The
adjustment procedure is the same for
both.
