petwar Posted October 1, 2010 Report Share Posted October 1, 2010 is it possible to change the seal without removing the shaft? Or is it possible to remove the shaft without splitting the engine cases? Quote Link to comment Share on other sites More sharing options...
feetupfun Posted October 1, 2010 Report Share Posted October 1, 2010 What seal? What shaft? Sounds like you are asking about one of the crank seals or maybe even the seal behind the sprocket Quote Link to comment Share on other sites More sharing options...
woody Posted October 1, 2010 Report Share Posted October 1, 2010 Clutch arm - it's in seriously small print in the title This is from memory but I think the arm should just pull out after it has been lifted as far as it will go, then turned as far as it will go then lifted again. Can't remember which way it turns. I think this is how it comes out, same as on a YZ engine (I think again) Memory is not so good but give that a try.

feetupfun Posted October 2, 2010 Report Share Posted October 2, 2010 (edited) yes you can change that seal without splitting the cases but my memory is a bit different to what Woody said. he may be right its a while now for me but my memory tells me that you will need to pull the clutch cover off and remove the clutch pressure plate to allow the actuating arm cam shaft to slide out.

petwar Posted October 3, 2010 Author Report Share Posted October 3, 2010 yes sorry, it is the clutch arm. Basically it looks as if somepoint its snapped a chain and pulled it round the front sprocket damaging the guard lugs and the casing where the clutch arm shaft enters the gearbox. Im hoping i can repair it with a new seal and liquid metal as it leaks when the bike it leant over. Or whats the odds on getting a 2nd hand casing?
