Notice! 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.
– Park the machine on flat ground, lower the bucket to ground with
its plane down to avoid rolling the bucket.
– Run the engine at low idle speed, turn the bucket clockwise on the
ground until left boss top of bucket contacts the arm.
– 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 Figure). The tab is half round, so it’s easy to push them
out with a screwdriver after loosening the bolt.
– Loosen the bolt slightly with a spanner. Push out all the tabs in the
clearance c between the pressure plate and bucket.
– Push the bolt to one side of arm, and eliminate the whole
clearance a between arm and cam. Push the cam onto the arm to
increase the clearance b, and measure the clearance b with a
feeler gauge, which shall not be adjusted below 0.5mm.
– Attach the adjusting shims as much as possible in the clearance b.
Note: be sure to attach the residual adjusting shims in the clearance c
to avoid the damages to arm tail end face or bolt.
– Attach the residual tabs in the clearance c and tighten the bolt.
Note: the total number of tabs is 12 (6 pairs).
– If the measured value d is below 5mm, replace the cam.
