PARTS DISPOSITION
Handle the parts in accordance with your Warranty Bulletin on warranty parts handling.
Rework Procedure
Refer to appropriate service manual as necessary.
If this is the 3rd cylinder that has been replaced due to heavy liner polishing, then all remaining cylinder liners should be replaced following this rework procedure.
If oil consumption, blowby, and/or cylinder compression has exceeded the guidelines in the Operation and Maintenance Manual (SEBU7681) for In-frame Overhaul, then all cylinder liners should be replaced. Document the trends for these three parameters.
Procedure:
1) Verify and document single cylinder detonation of a particular cylinder by capturing logged events from Caterpillar Electronic Technician.
2) Perform all appropriate detonation troubleshooting for that cylinder. Refer to Troubleshooting Guide, "Detonation Occurance". Verify that the ignition system, detonation system, engine wiring, and valve lash are not the cause of the detonation alarms. It is also important to ensure that the engine is applied properly, for example rated for fuel, altitude, and ambient conditions. Use the appropriate Troubleshooting Manual for this step.
3) Use a boroscope to verify cylinder liner polishing is occuring prior to replacing the cylinder pack.
Note: Follow Dissassembly and Assembly Manual for the appropriate removal and installation procedures. Cleanliness is an important factor. The exterior components should be thoroughly cleaned before beginning the dissassembly procedure. This will help prevent dirt from entering the internal mechanism. Precision components can be damaged by contaminants and/or by dirt. Keep components covered and protected at all times.
4) Remove the single cylinder pack experiencing detonation.
5) Verify the piston part number is one of the following: 262-2061, 262-2063 or 262-2065. If it is not, the piston will need replaced. The information below will help to identify the correct piston part number for your application.
Appropriate piston part numbers:
For G3516E and G3520E 1500 rpm use 262-2063 piston.
For G3520E 1200 rpm use 262-2065 piston.
For engines containing old piston part numbers, the new pistons (262-206X) and the old pistons can be in the same engine. Dimensions and weights are the same. If a new piston is to be installed in a cylinder where an old piston was removed, the piston oil jet for that cylinder will need to be replaced with the 260-0135 oil jet.
For single cylinder replacements of the old piston with a new piston (262-206X) and oil jet, it is not necessary to install the new oil pump relief cover. If this program is being performed to replace all cylinder packs and oil jets in the engine to the new part number, the oil pump relief cover should also be replaced with the
