Jeffy,
Upon what tested data do you base the lifting capacity decrease in FEL opinion? Pivot friction is a function of lubrication, cylinder or valve leakage are maintenance issues. Both my Lull and IH will lift at specification w/ proper ballast. Maintenance is an expectation of safety and ownership. Speculation is again, not fact.
I agree. I could see the relief valve spring loosening up a bit causing pressures to drop. But that's easily fixed by readjusting or shimming the relief valve.
