Competition / Racers • G80CS crankshaft endfloat – Advice please

Hi im a newcomer to AMC and the club. Im just in the process of stripping my very late G80CS engine number 556X so one of the very last. I have the engine on a stand, all the primary side, rotor/crank sprocket removed and was just working on the timing side removing the Norton type oil pump. As i pulled the pump from its studs I `noted quite a significant axial/end float movement on the crank, a mm or two (oh no being my instinctive reaction LOL) does this suggest i will find something very nasty or missing when i split the crank cases or is the crank simply pulled/held axially against the drive side main bearing when the rotor nuts are tightened up – the latter would surprise me, but pleasantly on this occasion. Your advice/experience appreciated
