All the K0 shafts i have had problems with were all blue due to over heating. The other problem was a few had the oil guide plate missing ( PN 23106 323 000) and CMS list this plate on engine number 1018728 onwards. With out this plate the bearing was also burnt out and some had damage to the casing.
Ash, what is the part number in the Japanese parts book?
All of the shaft problems i have seen, have been on early K0's and nearly all have been around the 5.000 to 7.000 miles A member on this forum has a UK, 500K0 that has a locked engine at low mileage and i suspect that this engine lock is due to the shaft problem.
