Just installed a 95mm BC Crank to a rebuilt engine bolted to an OS Giken Twin plate clutch.Engine won't crank, crank pulley can't turn.Disassembled the gearbox housing to find out that the clutch was pressed against the gearbox internal structure(Chaffing marks on the clutch cover, crank could rotate freely after removing gearbox).Will be taking measurements of the crank mounting head to check for abnormal length.Did BC mentioned that modifications to the gearbox housing needed to be done? Did BC tested the cranks with twin plate clutches? Any other ppl experienced the same problem?

 

how do you know that the os giken tiwn disk wasnt too thick and get caught on the housing. i have heard of jdm twin disk rubbing up in the internal webbing of the trans

bcos I've used the same clutch on older 95mm crower crank, b20 and b18c cranks without any problems.
