Do not mix oil types. Any mixture or any unapproved oil couldlead to seal deterioration and leaks. A leak could ultimately cause the loss of fluid, which could result in loss of power steering assist.OPERATING PRESSURE & OIL FLOWRoss HF54 SeriesMaximum operating pressure is 1500 PSIMaximum flow rate is 6 GPMNOTE: The recommended minimum flow at 1 1/2 hand wheelturns must be no more than 2.5 GPM. If the HF54gear is operating an assist cylinder, more flow may berequired based on size of cylinder and front axle weight.Ross HFB52 SeriesMaximum operating pressure is 2000 PSIMaximum flow rate is 6 GPMNOTE: The recommended minimum flow at 1 1/2 hand wheelturns must be no less than 2 GPM. If the HFB52steering gear is controlling an assist cylinder, more flowmay be required based on size of cylinder and front axleweight.Ross HFB70 SeriesMaximum operating pressure is 2000 PSIMaximum flow rate is 8 GPMNOTE: The recommended minimum flow at 1 1/2 hand wheelturns must be no less than 3.4 GPM. If the HFB70 iscontrolling an assist cylinder, more flow may be requiredbased on size of cylinder and front axle weight.Ross HF64 SeriesMaximum operating pressure is 1750 PSIMaximum flow rate is 8 GPMNOTE: The recommended minimum flow at 1 1/2 hand wheelturns must be no less than 3.4 GPM. If the HFB70 isgear is operating an assist cylinder, more flow may berequired based on size of cylinder and front axle weight.Ross HFB64 SeriesMaximum operating pressure is 2000 PSIMaximum flow rate is 6 GPMNOTE: The recommended minimum flow at 1 1/2 hand wheelturns must be no less than 2.9 GPM. If the HFB52steering gear is controlling an assist cylinder, more flowmay be required based on size of cylinder and front axleweight.Ross TAS40, 55 & 65 SeriesMaximum operating pressure is 2175 PSIMaximum flow rate is 7 GPMNOTE: The recommended minimum flow at 1 1/2 steeringwheel turns per second is as follows: TAS40no lessthan 2.2 GPM. TAS55no less than 2.6 GPM. TAS65no less than 3.0 GPM. If the gear controlling an assistcylinder, more flow may be required based on size ofcylinder and front axle weight.16 − 29
