Replace the bucket
Note: avoid the injury caused by the flyout of metal filling or fragments in case of hitting out or
in the connecting pin, and wear the safety goggles or safety
glasses and safety appliances applicable for operation.
a)
Park the machine on flat ground. Fall the bucket to ground, fix its plane
on the ground, and ensure the pin shaft can’t be rolled after removing the
pin shaft.
b)
Side O-ring out as shown in Fig. 2-48.
c)
Remove bucket pin shafts A and B, separate the bucket rod bucket, clean
pin shaft and pin hole, and apply enough lubricating oil to pin shaft and pin hole.
d)
Align the bucket rod and new bucket, and ensure the bucket can’t roll.
e)
Attach the bucket pin shafts A and B.
f)
Attach the lock pin and retaining ring to pin shafts A and B.
g)
Adjust connecting clearance of bucket at pin shaft A (see “Adjust
connecting clearance of bucket”).
h)
Apply the grease to pin shafts A and B.
i)
Start the engine, and run it at low idle speed. Turn the bucket slowly in both
directions to check if the rotation of bucket is disturbed. Don’t use any disturbed
machine. If any disturbance, deal with it in time.
Adjustment of bucket joint gap
There is a regulation system of bucket connection gap capable of eliminating the connection slashing. When
the connection slashing is increased, remove or attach the tab as described below.
a)
Park the machine on flat ground,
fall the bucket to ground with its
plane down to avoid rolling the
bucket.
b)
Run the engine at low idle speed,
turn the bucket clockwise on the
ground until left boss top of bucket
contacts the bucket rod.
c)
Stop the engine. Pull the safety
locking rod to LOCK (lock).
Note: in case of removing the tab, don’t remove the bolt (Item 1 shown in Fig.2-51). The tab is half
round, so it’s easy to push them out with a screwdriver after loosening the bolt.
d)
Loosen the bolt slightly with a spanner. Push out all the tabs in the clearance c between the pressure
plate and bucket.
e)
Push the bolt to one side of bucket rod, and eliminate the whole clearance a between bucket rod and
cam. Push the cam onto the bucket rod to increase the clearance b, and measure the clearance b with a
