How to replace final drive seal on a 05 Kx250f

[D3ALN]

Does anyone know where there is a step by step guide? Would like to have a go at doing myself.

Pretty straight foward.

Take off the cover. Remove the sprocket. Pry the seal out with a small screwdriver being careful not to damage the case working around the circumference to make it easier for yourself. Make sure the spring gaiter comes with the seal or is removed from the shaft if it falls off.

Apply a light coat of clean oil around the new seal outside and inside edges, gently fit it square and push it evenly in with a socket (if you have one that's just smaller than the OD of the seal and deep enough to go over the final drive shaft) or just use a 3/8" drive extension to apply pressure around the outside edge of the new seal pushing it into the housing in a pattern as if you were tightening wheel nuts on a car.

I should clarify. Don't attempt to put the screwdriver in between the engine case and the seal - that WILL damage the case. I just pierce the face of the seal to pry against.

Thanks for that But i am stuck at getting the sprocket off at the moment as I dont have a circlip tool is there another way to do them?

I got it off is it ok to hammer the screwdriver in to old seal to get off? Id say its the orginal the one in there.

Yes... but be aware there's a bearing behind there!

I don't understand.

I don't understand.

sorry there is a piece of pipe that goes round the shaft in the inner diameter of the seal. It needs to go firther in but i cant get it to go do you have any tips and or tricks to do it. Asat the moment when I out the sporocket on it sits out too far and I cant get the circlip in the indent. Hope this makes sense

Part #92152A?
There doesn't seem to be any special trick - it's just a plain collar. But why did you take it out?

ok there should have been an oring behind spacer, make sure that is not folded preventing the spacer going back in,

I think you'll find, since the two o-rings are the same part number, that they're both inside the collar and on the smooth machined section of the output shaft or there would be a path for oil to exit/dirt to enter the box along the outside of the final drive shaft and under the collar.

I'd say the o-ring just isn't over the step in the shaft yet.

If there's a metallic noise as it bottoms out as it currently is (i.e. proud of the spline so you can't get the sprocket on) then it possibly needs to go inside a rebate in 13262E. I doubt that though as that would be rather crude given that gear spins independant of the shaft until dogged. I suspect that the gear has simply slid along a little and the gearbox is actually in 2nd not neutral as it should be and the dog needs to be returned to neutral with the shifter.

I would simply check the gearbox is in neutral, remove the collar and inspect the o-rings then lubricate with clean oil and push it on evenly.
