Hi Michael,
there are two places for pressurizing the lg struts: You checked the bottom filling
valve but that is just for extra hard landings when a second piston gets
active, which is sitting in the top of the hard chromed inner telescope. This
filling does nothing for the standing height. Look way up at the painted outer
section of the lg strut, there is another filling valve next to the brake hose,
see photo below. There you can add oil or change it by fully compressing the
strut to get old oil out. Dont know about the amount of oil but you found some
numbers. Anyway, at the top filling valve you can add some more air, nitrogen
no real argument. But dont do excessive pressure, it would give you a harsh
ride. Id want some angle in the brackets that align the wheels for parallel tracks.
In case you disassemble the whole landing gear Id suggest to bin these old felt
seals at bottom , they collect a mass of dirt and lead that into the strut
and destroy bushes and hard chrome. Better have real dirt wiper seals there, like
on motor bike teles, saves you precious hard chrome restoration costs.
cheers
Vic
