David, thanks for the information. I stand corrected. I thought these fittings were obsolete but I see Amazon is still happy to sell me all types of them!
Mike, I suspect the 4 gallons per suspension unit is correct. Each unit is about 3 feet long, about 10" wide and the shock absorber section at the top is about 6" deep, which works out to be a volume of about 8 gallons. I'm reluctant to commit 16 gallons of oil to the 4 suspension units that have shocks without being sure that it's doing something useful. According to our expert here, the T-54 didn't have shocks either. So did they go out of fashion after the war?
What puzzles me is if you neglect the shocks because they are not effective, what happens when they'd seize up?
