The High Pressure HP system reduces hydraulic pressure to retract and tension the CDP to approximately which PSI?

• A. 500-510 PSI
• B. 100-120 PSI
• C. 250-300 PSI
• D. 900-950 PSI

Answer: (A)

The main idea is how the high-pressure hydraulic control sets the force to move and hold the CDP in the retracted, tensioned position. This system is tuned to about 500–510 psi, which provides enough hydraulic force to retract the CDP and keep it under the proper tension without overloading the components. If the pressure were much lower, such as 100–120 psi or 250–300 psi, the force would be insufficient to fully retract or properly tension the CDP, leading to incomplete movement or slack. If the pressure were much higher, like 900–950 psi, the force could exceed design limits and risk damage to seals, hoses, or the actuator, or cause unstable operation. So, the 500–510 psi range is chosen to achieve reliable retraction and correct tension safely.
