SERVICE PROCEDURE
TURN, REPLACE BOLT-ON CUTTING EDGE
WARNING
It is dangerous if the work equipment moves by mistake during the turning or replacement operation.
Set the work equipment in a stable condition, stop the engine, then set the work equipment lock lever securely to the LOCK
position.
Turn or replace the cutting edge before the wear reaches the edge of the bucket.
1. Raise the bucket to a suitable height, then put blocks (A) under
the bucket to prevent the bucket from coming down.
Raise the bucket so that the bottom surface of the bucket is
horizontal.
2.
Remove nuts and bolts (1), then remove cutting edge (2).
3.
Clean the mounting surface of cutting edge (2).
4. Turn cutting edge (2) and install it to the bucket. When turning
the edge, install it to the opposite side (left edge to right side,
right edge to left side).
If both sides of the cutting edge are worn, replace with a new
part.
If the wear extends to the mounting surface, repair the
mounting surface before installing the cutting edge.
5.
Tighten nuts and bolts (1) uniformly so that there is no gap between the bucket and cutting edge.
Tightening torque for mounting bolt: 745 ± 108 Nm (76 ± 11 kgm, 549.7 ± 79.6 lbft)
6. Tighten the mounting bolts again after operating for several hours.
