Tr280I Output Shaft Seal

Featured Replies

my 2013 has started to leak oil from the output shaft... i see on the parts list there is a bush with 2 o rings behind it... im guessing if i remove the front sprocket i can then remove the bush and o rings.... but can the actual seal be removed without pulling the gearbox out?

thanks

Does your bike not have a 2 year warranty - get the dealer to sort it

Its 99% certain you will be able to replace the seal without pulling the gearbox.

With the bush and o rings removed I would think you could get a hook in to pull it out. I am surprised it is leaking, are you sure it is not blow from the crankcase breather which is often routed near the front sprocket?

Thanks all.. yes it does have 2 year warranty. . But nearest dealer is 80 plus miles away.. hardly worth the fuel for the price of the seal..

Canada. . Do you mean the elbow that comes from the casing in front of the sprocket? If so its def not.. its wet and running from output shaft down on bash plate.. it can tick over or rev not moving and no sign of oil... after half hour riding its wet through.. drained oil off and measured to make sure I hadnt over filled but only 275ml came out with clutch case backed off.. rest of 350ml is im guessing lost.. on a plus side my chain is nicely oiled up now :-)

That is what I meant so looks Ike that is not the issue. Can you tell if the oil is coming from between the collar and shaft or between the collar and seal just in case one of the Orings had failed and not the seal?

Its hard to see.. tried running it with the front sprocket off in gear to see if I could replicate it.. but couldnt tell.. the o rings are behind the collar arent they? I can see it weeping but its coming between where collar meets seal if that make sense.. had to lean the bike over

To the left to get it to leak.. couldnt feel any play in output shaft so good news.. heow does that collar come off as seems fairly attached to where it is.. mole grips couldnt pull it out

Orings fit inside the collar to seal the haft, the collar then sits inside the seal, between them they keep the oil in. It is a tight fit but I think it is only being held by the seal lip and the orings
