ADD SHIM TO BUCKET
Install a new bucket
1.
If you want to install new bucket, you should measure the
dimension of between internal lugs of the bucket and the
dimension of bucket link width.
2.
Subtract one dimension from the other, and you will get the
dimension of the shim you want to add on both sides. Add
the sheet before assembling.
When you check the gap at bucket connection, the bucket is
in free status. Otherwise, you should lower down the bucket
to the ground and use supporting block to fix the bucket. Stop
the engine, lock the safety lever, hang the warning sign and
prevent the bucket from moving.
The method with which the shim is added
when the bucket is installed
1.
When the bucket is being connected, the bucket will be
retracted and the bucket link will extend outwards to lower
arm to make the bucket teeth several centimeters away
from the ground. At such position, it is easy to measure the
dimension.
2.
After the O-ring seal is installed, you should push the buck-
et to one side to check the gap between the other side
of the bucket and bucket link. The total gap between the
bucket internal lug and the bush end face (Y, Fig.11) shall
be 1MM. If the fit is too tight (less than 1 MM), it will aggra-
vate the wear, and if the fit is too loose, it will generate too
much noise and the action will be slack.
3.
Push the bucket to other side to check the above gap
again.
4.
When it is needed to adjust, you should remove the back
cap( 1,Fig.11) and bolt (2) from the pin (3) , remove or add
shim (4). The same quantity of shims shall be used on both
sides. Install bolt (2) and nut (1). A gap of 1-2MM shall be
retained between the nut and the bush at the point "X".
