Benefits of Hy-Gard™

Features/Benefits
– Multi-viscosity formula for a wide range of operating temperatures
– Superior high temperature performance and oxidation resistance
– Fully laboratory and field performance tested
– High tolerance to water contamination without sludge formation
– Prevents final drive wear due to anti-wear additives for gears.

Applications
– Suitable for a wide range of operating conditions
– Transmissions and differential units with immersed wet brakes
– Gearboxes with hydraulic brakes
– Gearboxes with hydraulic drive systems
– General and high demand hydraulic systems requiring an ISO 46 or 68 hydraulic fluid.

Functions
Because some systems have combined transmission and hydraulic oil reservoirs, the oil must perform many different tasks at the same time. There is very little margin for error. Robust balanced properties are essential. To understand the complexity of transmission hydraulic oil, let’s review its functions.

– Prevents wear of heavily loaded gears and bearings
– Provides wear and corrosion protection for the hydraulic pump
– Provides proper friction for clutches to engage and absorb shock loads without excessive slipping or abrupt shifts
– Withstands extreme pressures in the hydraulic system without breaking down
– Prevents the formation of deposits on all internal parts
– Prevents foam and water damage to all internal parts
– Provides proper friction for brakes to ensure low chatter, long life and high capacity.
