MOUNTED EQUIPMENT
5.15.3. BLADE CUTTING EDGE AND END BITS MOUNTING BOLTS.
Check the torque of the blade cutting edges and end bit bolts after the initial 10 hours of operation
and then periodically. Lift the blade off the ground and block it. Stop the engine. Turn the electric
system master key off and remove it.
Fig. 5.42. Tightening Blade Cutting Edge Bolts
1. Bolt 2. Nut
Check the torque of the cutting edges and end bits bolts. It should be 455 [Nm].
WARNING! Never work beneath the blade without securing it with wooden
blocks.
5.15.4. ALLOWABLE WEAR OF CUTTING EDGE AND END BITS AND RIPPER
POINTS
Reverse or replace the cutting edge and end bits before the mounting plate is worn or damaged. If
the distance between a cutting edge mounting bolt axis and the cutting edge bottom edge is
smaller than 70 [mm] it should be reversed or replaced if it had already been reversed before. An
end bit should be replaced if the distance between the axis of a mounting bolt in the lower row and
the bottom edge is smaller than 80 [mm]. To replace the cutting edge and the end bits proceed as
follows:
1. Raise the blade about 300 [mm] above the ground and set the pilot valve lever in HOLD
position. Prop up the pusharms and stop the engine.
WARNING! Never work beneath the blade without securing it by wooden blocks.
2. Remove the cutting edge and end bits mounting bolts.
3. Install the cutting edge or the end bits and tighten the bolts to the torque 450 [Nm] .
Authorized Distributor of Construction Equipment can supply these specially heat-treated bolts.
CAUTION! Do not substitute bolts. Loosening of the bolts securing a cutting
edge and end bits may result in tearing off of the cutting edge or end bits and
blade damage or personal injury.
