BUCKET ATTACHMENT,
REMOVAL AND REVERSAL
Detaching the Bucket
Park the excavator away from obstructions on clear, flat, level
ground. Lower the bucket carefully to preassembled blocking on
the ground. Brace the bucket so that there is no load weight on
the pin connecting the bucket and arm. Disassemble the
fasteners on the end of the bucket pin and pull out the pin.
If the pin sticks and resists normal withdrawal, there may be a
load on it. Raise and lower the arm slightly until an unstressed
pin position is located.
When the pin has been withdrawn, move the operating joystick
slightly to take weight off the remaining link pin. Disassemble the
link pin end retainers and pull out the pin.
Lift the arm away from the bucket so that the bucket can be carried
away or another end attachment can be put on the excavator.
Attaching the Bucket
Carefully inspect all parts before reassembling the bucket
linkage. Look for cracks or any other evidence of physical
damage and replace any seal or O-ring that is not in like-new
condition. Prelube linkage pins before reassembly.
Use an old cylinder rod, a long breaker bar or a similar, relatively
thin diameter support bar for making the first (temporary) pin
connection, between the bucket and arm. If the support bar is
straight, the arm can be raised and the bucket will hang level,
allowing direct insertion of the bucket ear-attachment linkage pin.
When the link pin has been installed, withdraw the temporary
support rod from the bucket pin holes, lower and raise the arm
and boom and install the bucket pin.
CAUTION
Use care pulling out the pin to avoid damaging the dust
seals on either end of the arm.

WARNING
When making linkage alignments, never insert fingers into
pin holes. The attachment or bucket could shift position
and cause a severe injury. Match holes by visually lining
them up. Use the sharp-tipped, soft point of a pencil or a
similar tool to check for high spots or irregularities.
