Key crankshaft specs (field-useful)

• Overall gear ratio: 4.5:1 (108T / 24T), per A-1700-PT performance data.

• Stroke: 12 in → crank throw = 6 in (useful for rod calculations).

Power & torque context (for sizing work)

• Rated pump power: 1,700 HP; max speed ~150 spm (≈ crank rpm for this pump). At 1,700 HP and 150 rpm, approx. crankshaft torque ≈ 59,500 ft-lb (HP×5252/rpm), not including losses—use as a sizing guide only.
