SERVICE PROCEDURE
10. Store shim plates, which are not used, inside the wheel covers
on both sides as illustrated in the figure at right.
Thus the adjustment of the outlet clearance has been finished.
The machine is now ready for starting works.
CONFIRMATION OF LOCKING FORCE AFTER STARTING WORK
CAUTION
After adjusting the clearance at the outlet of the crusher jaw, be sure to carry out a trial operation under the trial conditions of
engine revolution at low idling and crusher revolution at MIN and confirm that there is no abnormal noise from around the
toggle block.
When inserting shim plates, confirm the total number and thickness of the right and left shims to ensure the identical shim
plate thickness on both sides.
Should the shim plate thickness differ between the right and the left sides, there would be a critical damage to the crusher main
body.
For some time after an operation is started with load, the locking
force may be reduced on account of insufficient contact of the
shims or fine foreign objects caught between the shims.
When adjustment was made of the clearance at the outlet of the
crusher due to the wear on the swing jaw plate and fixed jaw plate,
tighten the shim plates (toggle block) every 30 minutes of operation
until no backlash is confirmed.
Checking method
Hit the shim plates and the toggle block pins with a hammer to see
if there is any backlash.
REMARK
If the backlash can be settled by no means, remove all the shims once by pushing the toggle block to the extreme
front end, following the same procedure for the jaw crusher outlet clearance adjustment, and then blow them with
an air or water gun to remove foreign objects.
