Hi All,
I am trying to obtain a couple of oil seals for the 250 rebuild. I have the old seals (they are for the kickstart shaft and the clutch operating arm) they are both the same inside and outside diameter but their markings differ? One is marked as C14 SD 12 X 22 X 5, the other is marked as C25 SD 12 X 22 X 5.
I have tried various oil seal suppliers (Simply Bearings is one) and they all have 12 x 22 x 5 oil seals of various prices ranging from a cheap eurobrand up to SKF at four times the price. Some are nitrile, some are vitron. None have the C25 SD or C14 SD on their description
Can anyone advise what the C25 and C14 and SD marking actually mean?
