December 27, 201213 yr Should be the the same as the Rev, drain coolant (or lay the bike down, you will loose some coolant) remove the the water pump cover and the the circlip retaining the impeller. Remove the old seal (this can be a little tricky but the seal will come out with a little persistence) DO NOT PULL THE IMPELLER SHAFT as you can pull it out of the drive gear behind the water pump casing. After removing the seal inspect the shaft for wear if all ok grease the new seal with water proof grease and push the new seal into place with a socket that is very slightly smaller than the the seal. Reassemble the impeller and circlip replace the warerpump cover and add coolant. Job done. Flush your gearbox oil two or three times and all should be well.
January 9, 201313 yr Do not pull the impeller shaft? I just took off the case of my '05 Rev3 270 and looking on the inside, you can clearly see that the shaft is held in place by a pin. You won't be able to pull the shaft out from the outside. Maybe different on other bikes though...

January 9, 201313 yr then it must be "push" but one way will allow the pin to drop out and then it is a full clutch casing removal job to recover the pin. I stand corrected!
January 9, 201313 yr Author it was surprisingly easy just stabbed old seal and pryed it out knocked in new one with socket as advised above i would advise anyone doing this to change the circlip it is very flimsy
January 9, 201313 yr Author to be fair it wasnt leaking i was fitting the uprated jitsie pump but whats the point of changing that but leaving the old seal so prevention rather than cure
January 9, 201313 yr Author hard to say with the weather being cold il compare it with my mates next time we are out together and il let you all know
