Our friend “The Dicktator” did an excellent job of reverse engineering the OEM reservoir for the Roof Hydraulic System. The part is CNC machined out of a solid block of material with exactly the right interface to the hydraulic pump. In addition to replicating the OEM part, Dick had the capacity of the reservoir increased to add a little safety margin to the amount of fluid in the system. We are including the correct O-ring to seal to the pump and we have sourced the very special worm clamp that was selected by GM engineering.
This reservoir is an extremely high quality part that will be a great replacement for a leaking OEM reservoir.
We estimate that the correct fluid level of the new reservoir is at about half way up on the middle of the end of the reservoir. Look at the photos and use your imagination….. you will be able to visualize it. The bottom line is this…… there needs to be some free air space above the fluid at the end of the reservoir.
