As per good engineering practice the check is must especially if near sensitive equipments like pumps,compressors & turbines where an accurate alignment is required. The Spring must be restricted to 1mm, although your nozzle loads pass & safe in WNC still better to restrict it to 1mm.In such case why don't u try playing with operating load ranges & restrict the sus-spring movement. As good engg. practice, In such case on isometrics or spring specification you can put a note: Spring to be locked before maintenace,
