PROPER STEERING PUMP RATIO

PROPER P/S PUMP RATIO IS 50% OF CRANK SPEED

MAX P/S PUMP RPM: 5500

MORE THAN 5500, THE SUPPLY LINE CANNOT KEEP UP WITH THE PUMP THUS STARVING THE PUMP WHICH RESULTS IN AN OVERHEATED STEERING SYSTEM

PUMP TEMPERATURE READINGS

160º = NORMAL TEMP.        180º = WARM TEMP.        200º = PERMANENT DAMAGE TO SYSTEM

P/S PUMP RPM = CRANK PULLEY DIA.   = ?     X    MAX. ENGINE RPM

                                         P/S PULLEY DIA.

Examples:

P/S Pump RPM = 3”  =  .5   X   8000  = 4000       (SAFE RPM)

                            6”

P/S Pump RPM = 6”  =  1   X 8000  = 8000        (DAMAGING RPM)

                            6”

Solutions:

       1.   3” Arbor on front of crank with separate belt to P/S Pump  

OR

       2.   3” Pulley in front of Water Pump Pulley with separate belt to P/S Pump

NOTE:   ANY OVERDRIVEN P/S PUMP IS DAMAGED PERMANENTLY

                 &  NEEDS REPLACEMENT !
