How To Determine Ram Pressure
Do the following to determine what the pressure
gauge must show for your ram:
1. Determine the effective area of your ram.
2. Determine the minimum and maximum pressure
gauge readings desired.
EXAMPLE: Find the effective area of twin rams, each
ram having a piston diameter of 1.5 inch.
The formula for the effective area is:
Effective area = (d2 + d2) x 0.7854
d = diameter of each ram (1.5 inch)
d2 = d x d or 1.5 x 1.5 = 2.25 sq inch for each ram
Effective area = (2.25 + 2.25) x 0.7854 = 3.574 sq
inch
EXAMPLE: Find the pressure gauge reading for the
specified minimum and maximum lb ft force rising a
ram with 3.528 sq inch effective area.
Minimum pressure gauge
reading (PSI) = 2090 lb = 591 PSI
3.534 sq inch
Maximum pressure gauge
reading (PSI) = 2610 lb = 738 PSI
3.528 sq inch

STEP 80
Determine correct dimension as follows:
1. The reference number etched on the end of the
pinion shaft is a + or - adjustment in hundredths
of a mm.
2. Add or subtract the reference number from the
standard nominal dimension of 33.92 mm. This
will provide the desired dimension in mm.
3. To convert the desired dimension to inches,
multiply by 0.03937.
Example:
33.92 mm Standard Dimension
+0.22 mm Reference
34.14 mm Desired Dimension
34.14 x 0.03937 = 1.344 inches
