The product description states that all cylinders are fully maintainable and repairable. However, it does not specify if repair parts are readily available. I did not find any reviews addressing this question.
The operation of the hydraulic cylinder has nothing to do with the power of the hydraulic pump; it is related to capacity and pressure. This hydraulic cylinder requires 0.5 gallons (1.95 L) of hydraulic oil and an operating pressure of 3500 PSI (24 MPa). As long as the hydraulic pump meets these two conditions, it will be fine.
