Method For Checking And Replacing Alternator And Air Conditioner Compressor Drive Belt - Komatsu HD465-8 Operation & Maintenance Manual

MAINTENANCE
1.
Insert the checking gauge (2) which is one of the accesso-
ry tools into the wear check hole (1) of the calipers.
2.
Check the clearance between the stepped part of the
checking gauge (3) and the calipers (4).
When the stepped part (3) of the gauge (2) touches to the
calipers (4), it has reached the wear limit (thickness of pad
is 3 mm).
(A)
It is reaching to the wear limit.
(B)
Replace the pad since it has reached the wear limit.
Ask your Komatsu distributor for replacement of the pad (5).
The wear amount of pads on the right and left wheels are not
equal. Perform the check on both sides.
Replace all of 8 pieces if one of the pads reaches the wear lim-
it.
Wash the machine thoroughly after working in the muddy site.
Mud stuck to the calipers and discs promotes the wear of the
pad if it remains untouched.
