Sorry Ken, the crankshaft seals, hopefully the actual size so I can source them locally.
Cheers.

Hi ken, hope you see this. Iím getting gear box oil in my primary drive case. I suspect itís the gearbox oil seal. Is there an extra Ď1í in the part number above? Should it be 18113134? I.D like to order it before I start stripping the bike back.

Gearbox seal

Post  kerabo on Mon Nov 27, 2017 10:04 pm

Hello
Away from home for a few days and internet is slow.
If the mainshaft seal is leaking oil will just run on.to the floor. To get into the clutch case it has to pass through between the output shaft and the clutch input shaft. I don't think there is a seall on that but it's made to be above the gearbox oil level.
Check the level using the level bung and check the breather in the filler plate.
Regards Ken

Thanks for getting back to me. Iíve already dropped the oil in preparation for the strip but itís quite possible I over filled it. The breather (pin hole in plate?) is clear.

You know the level?
Slightly larger slotted screw?
