Selection of Hydraulic Components such as Couplings, Adapters, Flanges...etc selection of Bulk Hoses, Bulk Tubes based on the functional requirements (PST)
Routing Hydraulics lines using FLD (Fluid Lines Design)
SWVL analysis which used for Hose length validation as well as Hose Behavior in the articulating areas.
Creo Mechanism to make sure there is sufficient clearance with the other components in the articulating area like Boom, Stick Bucket cylinder lines clearance with Boom, Stick when they were at Max position.
Hydraulic Schematic Drawings are very good in Hydraulic Schematic reading.
