MER cannot guarantee torsional compatibility with unverified rotating components in an assembly. We highly recommend a qualified engineer review the mass elastic data of all rotating components of the final assembly to assure against premature failure. Neither MER or the engine manufacturer will warranty engine or associated equipment failures due to torsional incompatibility in absence of a Torsional Vibration Analysis (TVA).
