Many systems come with a standard paper media breather with a nominal rating of about 40 microns. is allows the smaller, more destructive particles to get into the system very easily. Upgrading a standard breather to a high-efficiency filter is easily done using commercial bayonet adapters and quality synthetic hydraulic filters. Protect Metals with Corrosion Inhibitors Corrosion inhibitors are additives that suppress oxidation and prevent formation of acids. ese inhibitors form a protective film on metal surfaces and are used primarily in internal combustion engines to protect alloy bearings and other metals from corrosion. ML Pre-Flush for Better Oil Samples It is important to recognize that the amount of tubing, the size of the sample port and the volume of static oil in relation to the location of the sample port can all disturb overall quality of the sample. For an effective, data-rich sample, appropriate pre-sample flushing volumes should be included in sampling procedures and should be specific for each individual sample port. e industry rule of thumb is to pre-flush six to 10 times the total volume of static oil in a sample tube, port, port adapter and any dead legs of pipe in the systems upstream of the sample port location.

Negligent handling can cause leakage or ingression of dirt. Each container used for in-plant lubricants should be used for only one oil, clearly marked for it and not substituted for another container. It should also be kept clean and sealed to keep out dirt. Never mix lubricants. adding another mist fitting to the bearing in question and increased the oil viscosity by one ISO viscosity grade. e bearing failure rate soon dropped, resulting in a mean time between repairs (MTBR) of more than two years. The second project was when our engineering team was replacing a dryer and asked me to review the OEM-recommended lubri- cation practices, since I had done a considerable amount of lubrication work on our other dryers to increase bearing life. I considered the ISO viscosity recommendation to be low, while the frequency and relubrication quantity were quite high. I contacted the manufacturer and met with a lot of resistance but eventually convinced them to enter into a partnership with Ingredion and a lubrication vendor. After a year of operation, we inspected the bearings and found them to be in an as-new condition. After the inspection, the grease recom- mendations for viscosity and relubrication frequency and quantity were adopted by the OEM. Our dryer also has been in operation for four years without any issues. ML
