Contamination can be devastat- ing to the performance and overall life of your machine's hydraulic system. Today's hydraulic systems are engineered with extremely tight tolerances. These tight toler- ances are what enable our hy- draulic systems to achieve higher pressures. These high pressures translate into the demands that are placed on our machines to help you maintain productivity and remain within your owning and operating cost targets. We refer to contamination as the "invisible thief" because many con- taminates are too small to be seen with the naked eye. One of the most common points of contaminate en- try into a hydraulic system is on the surface of the cylinder rod. When a rod becomes damaged as a result of scoring, pitting or denting for example, these imperfections on the surface of the rod can easily carry contamination into your hydraulic system as the cylinder rod retracts. Once contamination has entered the cylinder, damage can occur to the surface of the cylinder bore and internal cylinder piston seals. With damage to the cylinder bore and cylinder piston seals, internal leakage starts to occur and efficien- cy slowly begins to erode. Studies have shown that efficiency losses can reach up to 20 percent or more before the operator detects an issue with the performance of their ma- chine. When thinking of this figure in terms of productivity, 20 percent loss in efficiency translates to a loss of one entire day of production in a five-day week. Efficiency loss also reduces the overall performance of your machine and increases fuel us- age. As a result, your machine be- comes more expensive to run but with less productivity. Once contamination has entered the cylinder, it can also spread throughout your entire hydraulic s y s t e m a n d c a u s e d a m a g e t o other components such as pumps, motors or valves. Even worse, full system contamination may even lead to a catastrophic failure, leav- ing your machine down for an ex- tended duration and at a very high cost to repair. Contamination should be a ma- jor concern when a repair is per- formed. If care isn't taken to ensure contamination isn't kept out of your hydraulic system during a re- pair, it could cost you down time and high expense later on. Make sure anyone working on your equipment is aware of contamina- tion control. Cat ® dealers participate in a com- prehensive contamination control program of clean fluids, specialized tooling/processes, and Caterpillar- certified clean repair facilities to help reduce harmful contaminants during a repair. Dependent on your situation and needs, your Cat dealer can offer a hydraulic cylinder repair that is designed to accommodate your needs, prevent unplanned downtime and restore full efficien- cy of your hydraulic system.
