    Can't look it up to know without serial numbers.. .. since your asking I assume it engine serial number dependant?

    Sorry, all the info I have supersedes to the same crank number. 1A051-23015, now 23020, was originally 23012 and 23013, but both supercede the same so hardly a journal difference.

    Thank you…I guess I have to phone the dealer and ask for the part number. They want $3600US for the crank so wouldn’t be buying it from them!!
