MAG-SHIELDS® Protect the Hydraulic Systems of a CAT 994H Loader

The Problem October 2019 Hydraulic system reliability and durability were being compromised by heavily contaminated oil resulting in premature failures and reduced component life for CAT 994H loaders at an Australian mine site. All main hydraulic circuits share a common reservoir and hydraulic fluid. Contamination created by the failure of any one component can contribute to wear in other parts of the hydraulic system. The majority of the contamination produced by this type of failure is ferrous. Learn more

Brake Cooling Hydraulic Systems on CAT 994H Loader Guarded
by MAG-SHIELDS®

The Problem October 2019 Brake system reliability and durability were being compromised by heavily contaminated cooling oil resulting in premature failures and reduced component life. All four brakes share a common reservoir and hydraulic fluid, and the factory system is unfiltered. Contamination in any one brake assembly can contribute to wear in other parts of the brake system. Most of the contamination in the fluid is ferrous. Learn more

CAT 793D Off-Road Truck Guarded
by MAG-SHIELDS®

The Problem October 2019 A CAT 793D off-road truck being operated at an Australian mine site had a component failure within the brake hoist hydraulic system. This type of failure would release large amounts of ferrous material contamination into the hydraulic system, which could not be contained by the factory filtration system; factory filters would plug and enter bypass, allowing unfiltered fluid to circulate within the system. This would cause additional failures to the hydraulic
system, specifically damaging the pumps. Following a failure, even the most effective flushing techniques cannot remove all residual contamination. The residual contamination continues to circulate within the system and cause follow-on damage. Learn more
