Adjust The Bucket Linkage (Backhoe) - Hitachi Zaxis 850LC-3 Operator's Manual

3 Adjust the Bucket Linkage (Backhoe)

When play in the linkage increases, remove and install shims as
follows:
1. Park the machine on a level surface. Lower the bucket to
the ground with the flat side down so that the bucket will
not roll.
2. Run the engine at slow idle. With the bucket on the
ground, slowly swing counterclockwise slightly until the
top of the left bucket boss contacts the arm.
3. Stop the engine. Pull the pilot control shut-off lever to
the LOCK position.
4. Adjust the clearance between arm and bucket to become
from 0.5mm to 1mm (0.02 – 0.04 in) by Shims.
NOTE: The product is shipped with shims (1mm (0.04 in) : 2
pieces, 1.6mm (0.063 in): 1 piece) from the factory.
