Shimming Procedure

Note: Refer to this section when there is a joint that needs to be shimmed.

Illustration 1	g00296023

1. Remove all the shims from assembly (1) .

2. Install push arm assembly (1) and cap (2) on trunnion (3) without the shims. Tighten the cap while you maintain equal distance on both sides of the cap.

3. Insert as many shims as possible into spaces (A) and (B) between the cap and the assembly.

4. Add two additional shims to the total shims that are used.

5. Install half of the shims at location (A). Install the other half at location (B) .

6. This should allow the assembly to move freely on the trunnion and within the specified tolerance.

Calibration Procedure For the Lift Cylinder Sensors and the Electrohydraulic Solenoids

Show/hide table

Personal injury or death can result from not following the proper procedures. To avoid the possibility of injury or death, follow the established procedure.

Make sure that authorized service personnel perform the calibration procedure.

Show/hide table

If the lift cylinder position sensors are not successfully calibrated, machine damage can result due to a mechanical collision of the blade push arm and the tracks, the blade push arm bearing and trunnion bolts, the lift cylinder and the radiator guard, the tag link and the radiator guard, or the lift cylinder and the tag link.

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.

• 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 solenoid

• Ripper shank in solenoid and ripper shank out solenoid

The calibrations can be done only 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. The VIDS message center will display the following error.

• All EIC Sol. Out of Cal (CID 1298; FMI 13)

When one solenoid has been calibrated, the VIDS message center 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 VIDS message center 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 VIDS message center as logged events. The logged events can be cleared from the memory of the VIDS Electronic Control Module. Use the Caterpillar electronic technician.
