Rework Procedure
Recommended procedure for Before Failure Repair. (Groups 1 & 2)
1. The vibratory motor needs to be removed. Hydraulic hoses should be capped at time of removal to prevent contamination.2. Follow the attached service manual procedure for disassembly and assembly of the vibratory motor to remove and install a new 7X5497 Cylinder Block. If the cylinder block spline area has cracked and failed causing damage to the rotating group, the motor should be replaced with a new motor. Follow the attached "Recommended Inspection For After Failure Repair."
The new 7X5497 Cylinder block will come preassembled with Items 19, 20, 21 and 22 already preassembled. It will also have a dull grey appearance due to the nitriding process it has gone through. The older cylinder block will have a bright shiny appearance.
3. Stamp the letter "N" after the date code which is found on the motor identification plate. An example of a modified motor date code would be "A-95-03-12435 N ".4. Reinstall the motor and perform the Machine Frequency Test found in Testing and Adjusting, Vibratory System. It is not intended that the shaft seal, bearing or end cap be disassembled during completion of this repair. Only the 7X5497 Cylinder Block and 7R3403 Gasket should be replaced.
