A: If your PC35-2 exhibits slow travel or weak boom lift, check for excessive vibration or abnormal noise from the pump area. These symptoms often indicate internal cavitation or wear in the 708-3S-00511 cylinder block, necessitating an immediate pressure test to prevent downstream valve damage.
A: You must thoroughly flush the hydraulic system to remove metallic debris from the old pump. Before startup, fill the 708-3S-00511 case with clean hydraulic oil via the drain port to ensure the rotating group is lubricated, preventing a "dry start" which can cause catastrophic failure.
A: Always verify the 10-digit part number 708-3S-00511 on your existing nameplate. For PC35MR-2 models, check the input shaft diameter and the number of splines to ensure the pump interfaces perfectly with your engine's fly-wheel coupling.
A: Designed for global industrial use, the 708-3S-00511 utilizes high-specification seals that maintain integrity in temperatures up to 90 degrees Celsius. Its robust housing is engineered to resist thermal shock in sub-zero climates, ensuring consistent hydraulic viscosity and performance.
