clean it down, wip off the F sproket , you should be able to see if the seal is leaking, if it is, easy enuf to do, gently prize out old seal, try not to scratch the seal bore, then tap in new seal with a socket the same size dia as the seal, should cost you about NZ$10.00 for the seal, let me know if you have trouble getting a seal, I can post one out to you.

First you need to assess WHERE its leaking from-- around the shaft, or around the outside of the seal. If its around the seal, a good clean and a bit of silicone usually does the trick. If its the shaft, then Yes, it is possible to replace without pulling it to bits, BUT, it is risky. You will need to trim off a ridge around the seal to fit it, which raises the risk of it being spat out ,dumping the oil and seizing the engine. Also there is a risk of the countershaft being starved of oil buggering the gearbox if seal is not pushed in the right distance. If its not too bad then just look on it as an automatic chain oiler till you get around to fixing it!

Might even be leaking from the clutch pin seal instead... I know mine was but I replaced both anyway since I was there.
