jfc Posted December 27, 2012 Report Share Posted December 27, 2012 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.

eugenevd Posted January 9, 2013 Report Share Posted January 9, 2013 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...

jfc Posted January 9, 2013 Report Share Posted January 9, 2013 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! Quote Link to comment Share on other sites More sharing options...
nelly1 Posted January 9, 2013 Author Report Share Posted January 9, 2013 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 Quote Link to comment Share on other sites More sharing options...
jfc Posted January 9, 2013 Report Share Posted January 9, 2013 Glad to hear it all went well, nice clean oil now? Quote Link to comment Share on other sites More sharing options...
nelly1 Posted January 9, 2013 Author Report Share Posted January 9, 2013 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 Quote Link to comment Share on other sites More sharing options...
