![]() “The Excalibre cylinder is nothing less than phenomenal,” said Woody. “Once it hits that targeted ISO count, the filter cart will automatically shut itself down.”Īnother big reason cited for the extra longevity is Pride’s adoption of Excalibre hydraulic cylinders from McNeilus Street Smart Parts. “Some carts will filter down to your preset ISO count setting, and by going down one ISO count you halve the amount of contamination,” explained White. Some haulers choose carts that can run at night and shut off once the job is completed. That’s where the value proposition is.”ĭepending on the type of filter cart, a technician can attach it to the vehicle’s quick disconnects and allow the cart to filter the hydraulic system while completing a brake job or other maintenance or repair procedure. “If you can extend the oil life, the savings are significant. “The typical truck has 50 gallons of hydraulic oil, and the cost is up to nine dollars per gallon,” said Bob White of Schroeder Industries. By lowering the ISO cleanliness codes, you significantly extend the life of your hydraulic oil. The objective is to lower your ISO counts, which measure the amount of contaminants in hydraulic oil. Run trucks through filtration at a baseline minimum of at least every six months to cleanse its systems. ![]() “Now, you not only have ingested contaminants suspended in the oil but you’ve added metal particles.”Įxternal filtration treatments should be done on a regular schedule. “As the contaminated fluid gets inside the hydraulic pump, it wears down the internal components leading to catastrophic failure,” explained Spadell. The problems can quickly escalate as contaminants circulate throughout the system. As it circulates, it wears the inside linings of the hydraulic lines as well as other components,” said Dave Spadell, Director of Refuse Sales for Mailhot Industries USA. “Contamination found in hydraulic oil acts like little pieces of sandpaper. ![]() Once a contaminant is introduced, it flows through the entire hydraulic system from the pumps, through the lines and all the way back to the reservoir. The effects of contamination comprise a laundry list that includes some of haulers’ most pressing issues: loss of vehicle efficiency, fine controls and position holding, internal leakage, sticky and erratic controls, and rust and corrosion. ![]()
