WebWear metals like iron, copper, and tin should be alarmed at levels of 5 ppm or higher when the sample is pulled from the reservoir. Bearing-specific drain samples should have lower wear metal limits. Contaminants like silicon should be kept below 25 ppm. Testing for metals should be conducted on a monthly or quarterly basis. Before the use of oil analysis, a dust entry problem would go undetected until a routine teardown or a failure occurred. Even then, often the wear would be attributed to lubricant breakdown or normal wear and tear. With the use of oil analysis the picture changes. As soon as a dust entry problem occurs there is … Ver mais It is unlikely that there will be a dust entry problem without an increase in wear rates. If normal wear patterns combine with high silicon readings, there are two main possibilities: (1) a silicone sealant, grease or additive is in use, … Ver mais This indicates that dirt is getting into the lube oil directly and not past the pistons and rings. The likely sources are: (1) leaking seals, (2) defective breather, (3) damaged seal on oil filler cap or dipstick, or (4) dirty storage … Ver mais This is the worst case. Carry out all checks for top and bottom wear. Several other checks must also be done: 1. Was any repair work done to the engine?
