The silver adapter replaces the accumulator and has a JIC fitting on it for a remote accumulator. It fits in place of the original like the gold one on the left.
Used a small block chevy valve spring to hold the adapter against the lock ring. The original was held in place by the gas pressure. An O-ring seals it.
Made dimensions the same as original.
The bigger silver accumulator is what I'm going to adapt to the hydroboost. It is 3 to 5 times larger in capacity than the stock size units on the left. Removed from a DC-10-40 when it was decommissioned.
We went on a BBQ tour, Missouri, Tennessee, Arkansas, Oklahoma. The ribs we got in Missouri were the best.
Missouri mines state historic site. Missouri has a lead belt and this mine was turned into a museum with a huge collection of minerals from all over the world. There are hundreds of miles of tunnels now flooded. The Doe Run mine is in operation today in the area. Located by Park Hills on highway 32.
Beale street Memphis Tennessee
Martin King museum. The cars are like the original ones that were parked there.
I'm using the caveman c-clamp method of compressing the accumulator so the lock ring can be removed. There is an official tool for this but I don't have one. The pin punch fits in a hole that pushes the lock ring in enough to fish it out with a seal pick. The accumulator goes in about 1/8 inch against the stop in the housing. If the nitrogen is gone the accumulator will wiggle in the housing as there is no pressure pushing it out...one test for a bad accumulator.
There is an O ring that seals the housing to the accumulator. The lock ring is at the bottom of the picture.
The blue accumulator is for disc/disc brakes charged to 450 psi and the gold for disc/drum brakes at 350 psi. Gold is the type needed for our GMC with original brakes. There are other types of these, some remote mount types and at least one using a spring instead of nitrogen for pressure.
