Kevin, I'm thinking that the spacers and the Belleville springs have the same effect: They make the stack taller when the stack is compressed by the weight of the plane while on the ground. When the weight is off the plane, the stack expands to the limits. When the weight is on the stack, it compresses till the resistance matches the weight. Apparently, good, new Belleville springs hold the compressed stack up higher than do compressed donuts. Ed
