IMPORTANT!
Avoid using too much grease as
excessive grease will cause overheating
and shorten the bearing life.

CHAPTER 5 - MAINTENANCE
5.3.4 Eccentric Shaft Bearing
Temperatures
Bearing temperature should be checked frequently
and greasing accomplished immediately if an
unusual temperature rise is noted. During
operation, bearings will feel warm to the touch but
it should always be possible to touch them for a few
seconds without discomfort to the hand. Normal
bearing operating temperature is 40-70°C
(104-158°F). Should operating temperature reach
75°C (167°F) or in very warm conditions 90°C
(194°F) a check should be made to determine the
cause. A check should also be made, if one bearing
is over 10-15°C (18-27°F) warmer than the other
bearings.

IMPORTANT!
C Series crushers are not designed to
operate at temperatures lower than
-30ºC/-22ºF. Should operating
temperatures be lower than -30ºC/-22ºF,
contact Metso.

IMPORTANT!
If temperature sensors are not installed
on the crusher, temperature reading
must be done when the crusher is at rest.

APPENDIX B
9. Operating instructions

a. Clean lifting holes of the cheek plates
ensuring that the cam of the cheek plate
lifting tool can be placed in a locked
position.

b. Cheek plate lifting holes can be kept
clean by filling them with polyurethane.
The polyurethane must withstand
ambient temperatures and must be
melted away with a torch prior to
inserting the cheek plate lifting tool.

c. Rotate the locking handle of the cheek
plate lifting tool in a down vertical
position. This aligns the lifting pins with
the cam of the tool.

d. Insert both lifting pins of the cheek plate
lifting tool into the lifting holes, and
rotate the locking handles 180 degrees in
the up vertical position.This off-sets the
cam from the locking pin,and prevents
the pin from sliding out from the lifting
hole. To prevent the tool from premature
disengagement from the cheek plate, a
locking wing nut is screwed in finger
tight

e. Remove all slack from the chains of the
cheek plate lifting tool.

f. Remove all wedge bolts and wedges.
Make sure fines are cleaned from
between the jaw dies and crusher cheek
plates.

WARNING!
Before lifting any wear parts, check the
weight of the component and ensure that
the lifting equipment being used is
adequate to lift the weight.

DANGER!
Never place yourself or other personnel
in a position beneath or adjacent to a
cheek plate that is not properly secured
against unintended movement. A
worker must never be in the crushing
cavity while a cheek plate is being lifted
out or lowered in.
