Connect hose assemblies (30), (50), (34), and (50A) to the hydraulic ports on the radiator guard. Use seals (19), flanges, washers, and bolts. Tighten the bolts to a torque of 50 10 N m (37 7 lb ft).Note: The items that are not numbered are part of the lift cylinder lines. The parts are on the machine.
Check the oil in the hydraulic tank. If necessary, fill the hydraulic tank. Cycle the cylinders by a full stroke. Cycle in both directions in order to purge air from lines and cylinders. Refill the hydraulic tank to the "FULL" mark.
After assembly is complete, prepare the machine for operation. Refer to the Operation and Maintenance Manual for proper machine preparation. Calibration Procedure For the Lift Cylinder Sensors and the Electrohydraulic Solenoids
Personal injury or death can result from not following the proper procedures.To avoid the possibility of injury or death, follow the established procedure.
Note: Machine performance will be significantly affected if ANY of the calibration procedures are omitted.After installation of the bulldozer, the lift cylinders, and the ripper is completed, the following sensors and Electrohydraulic solenoids must be calibrated. Calibrate the sensors and the solenoids in the sequence that is specified below.Note: The lift cylinder sensors only apply if the machine is equipped with auto carry.
Lift cylinder position sensors
Blade lift and raise solenoids
Blade tilt left solenoid and blade tilt right solenoid
Ripper shank raise solenoid and ripper shank lower solenoidThe calibrations can be done with a Laptop computer. Use Caterpillar Electronic Technician software version 2.3 or higher.Turn the ignition key to the ON position. Machines that have not been calibrated will display the following error.
All EIC Sol. Out of Cal (CID 1298; FMI 13)When one solenoid has been calibrated, the monitoring system will display the following individual errors.
Right lift cylinder position sensor (CID 0869; FMI 13)
Left lift cylinder position sensor (CID 0870; FMI 13)
Blade raise solenoid (CID 1198; FMI 13)
Blade lower solenoid (CID 1197; FMI 13)
Blade tilt left solenoid (CID 498; FMI 13)
Blade tilt right solenoid (CID 497; FMI 13)If a ripper is installed, the monitoring system will display the following errors.
Ripper shank raise solenoid (CID 889; FMI 13)
Ripper shank lower solenoid (CID 888; FMI 13)
Ripper shank in solenoid (CID 886; FMI 13)
Ripper shank out solenoid (CID 887; FMI 13)When the calibrations and a keyoff/keyon cycle have been performed, all the errors should become inactive. However, the errors can still be viewed from the monitoring system as logged events. The logged events can be cleared from the memory of the Electronic Control Module. Use the Caterpillar electronic technician.Standard Torque for Fasteners
