Inspect Tool Holders for Excessive Wear or Damage
In cases of severe damage to cutters involving loss of the entire cutting head, the tool holder
tool face may be exposed to impact with potential for damage to the machined surface. Any
damage to the machined surface must be corrected. In
cases of severe damage, a new tool
holder must be installed.
Check Bearings for Excessive Radial clearance or Endplay
With the unit squarely on the ground, or other flat solid surface, and with the carrier in a
ZERO ENERGY STATE, slide a pry bar under the drum ting. Check for excessive radial
clearance. Readily visible movement while moving the pry bar up and down, may indicate
worn or damaged bearings.
Excessive endplay may be detected by placing a pry bar between the cutting frame and
either end of the cutting drum. A small amount of end-play
(approximately 1/16” (1.5mm) is
built into the bearing. If total axial play (in excess of 1/16” ) is detected, bearings may have
be replaced and further inspection is required.
Verify Cutter Fastener Torque
Using a torque wrench, check that all cutter bolts are tightened to a value of 55 ft-lb (75Nm).
Inspect Hydraulic Motor, Valving and Hydraulic Hose Connections for Leaks
Place the unit squarely on the ground, or other flat solid surface, and ensure that the carrier
is in a ZERO ENERGY STATE. Allow the unit to cool to ambient temperature. Remove the
drive end cover and inspect the hydraulic motor and anti-cavitation valve assembly hose
connections for leaks or seepage of hydraulic oil and correct as necessary.
