COOLING SYSTEM:
Check the level of coolant in the radiator overflow tank daily. Add a mixture of antifreeze and
distilled water to the overflow tank as required to maintain the coolant level. Check the radia-
tor fins for dirt or debris daily and wash the fins with a pressure or steam cleaner every 50
hours or as required. Check the antifreeze protection level every 500 hours. Every 2 years,
flush the cooling system and replace the thermostat and coolant. Pressure test the system as
specified by the engine manufacturer.
SPARE PARTS LIST:
A spare parts list (including oil filter, fuel filter, etc.) may be found in the Parts Manual, under
Engine Installation.
MAJOR ENGINE SERVICING OR OVERHAUL:
Major servicing or overhaul is beyond the scope of this manual. Consult authorized engine
service manual or rely on an authorized engine service center
.
MECHANICAL ADJUSTMENTS
FASTENERS:
All fasteners on the IC-200 should be checked and retightened if required, as a part of the pre-
ventive maintenance program. Particular attention should be given to the drive axle mounting
bolts, pump mounting bolts, pump drive shaft bolts, rotation bearing bolts, rotation gearbox
bolts, winch bolts, etc. All bolts used in assembly are heat-treated Grade 5 or better. Torque
the wheel nuts to 500 foot-pounds (680 Nm). As part of routine maintenance, inspect several
of the swing bearing mounting bolts or nuts to 270-300 foot-pounds (370-410 Nm). Note the
inspection torque is less than the installation torques. If any nuts or bolts rotate at less than
the inspection torque, re-torque all swing bearing fasteners to the installation torques. See the
turret sub-assembly and turret installation drawings in the parts manual for installation torques.
The torque chart on page 3-29 can be used on all other bolts.
ROTATION GEARBOX:
The rotation gearbox assembly is attached to the chassis top plate by four capscrews. It is
held in proper engagement with the external teeth on the bull gear by two setscrews. It is fur-
ther restrained from torsional movement by two bolts on each side of the gearbox mounting
flange. The gearbox should be adjusted with the boom centered over front of the chassis.
This centers the gearbox pinion on the “high side” of the bearing gear teeth. Adjust the gear-
box inward until there is “light contact” between pinion and bull gear teeth. Retighten the four
mounting bolts and the four side bolts.
TRANSMISSION AND AXLE TROUBLESHOOTING AND OVERHAUL:
Procedures for transmission and axle troubleshooting and overhaul are beyond the scope of
the BMC Maintenance and Parts Manuals. International Transmission Ltd. factory service
manuals are available from BMC as follows:
Transmission Service Manual, BMC Part Number 990-00021
Axle Service Manual, BMC Part Number 990-00020
PARK BRAKE TEST AND ADJUSTMENT:
1. Fully apply the parking brake.
2. Start the engine, retract the boom to the appropriate traveling position and raise the outrig-
gers.
3. Select fourth gear.
