I would like to ask if any of you are familiar with material thickness of sinusoidal springs for grasso rc12. the thickness of the discharge sinusoidal springs i got from actual measurement was 0.5 mm , and 0.8 mm for the suction sinusoidal springs. since no valve plates were damaged, i looked at the aftermarket, since our local grasso distributor will only sell the sets.

i got a quote from one aftermarket parts supplier. the material specs for the discharge is the same thickness, which is 0.5 mm , but i noticed that the material thickness for the suction sinusoidal spring was only 0.6 mm . was there a revision of the material specs from grasso that changed the suction sinusoidal spring material thickness from 0.8 mm to 0.6 mm ?

any advise from fellow grasso recips users ?

thank you
