Information:
The crankshaft vibration damper limits the torsional vibration of the crankshaft. The visconic damper has a weight that is located inside a fluid filled case.The damper is mounted to the crankshaft on the front of the engine. Damage to the damper or failure of the damper will increase vibrations. The increase in vibrations will result in damage to the crankshaft and to other engine components. A deteriorating damper will cause more gear train noise at variable points in the speed range.A damper that is hot may be the result of excessive friction. This could be due to excessive torsional vibration or misalignment. Use an infrared thermometer to monitor the temperature of the damper during operation. If the temperature reaches 100 °C (212 °F), consult your Caterpillar dealer. For long term monitoring, a temperature swatch 8T-2821 Temperature Indicator, should be attached to the damper on the outer ring.Inspect the damper for evidence of dents, cracks, and leaks of the fluid.If a fluid leak is found, determine the type of fluid. The fluid in the damper is silicone. Silicone is transparent, smooth, and viscous. It is difficult to remove silicone from most surfaces.If the fluid leak is engine oil, inspect the crankshaft seals for leaks. If a leak is observed, replace the crankshaft seals.Damper Fluid Sampling
At 15,000 hours take first oil sample. For sampling bottle and instructions use part number 436-0477. Damper can be sampled a maximum of ten times over the components life. Take oil sample every 4000 hours or by recommendation from analysis. Oil reaches end of life when degraded by 30% or from recommendation from analysisThe silicone oil fluidThe health of the damper fluid must be checked periodically.Take the first sample at 15,000 hours.Take the remaining samples at 4000 hour intervals or by recommendations from the fluid analysis.The fluid has reached end of life when the fluid has degraded by 30% or determined otherwise by analysis.For instructions on repairing the damper, refer to Guide for Reusable Parts, SEBF8152, "Procedures to Rebuild Vibration Dampers 3600 Family of Engines". The tools and instructions in the guide for reusable parts are appropriate for G3500 Engines.Inspect the damper. Repair the damper or replace the damper for any of the following reasons:
The damper is dented, cracked, or leaking.
The paint on the damper is discolored from heat.
The temperature swatch has been tripped for temperatures greater than 100° C (212° F).
• Fluid analysis indicates the silicon fluid has degraded from its original viscosity by greater than 30 percent.
The engine has had a failure because of a broken crankshaft.
Analysis of the engine oil has revealed that the front main bearing is badly worn.
There is a large amount of gear train wear that is not caused by a lack of engine oil.
