NC24 leaking oil. HELP
Hi all.
I have a '87 VFR400R that's been giving me hassles with oil leaks. My biggest concern is the leak originating behind the drive sprocket, on the gearbox output shaft. I have recently replaced this seal, an ordeal where one must remove the engine and split the lower crank casing, however the new seal does not seem to affect the leak at all. Is there anyone who may have some advice on stopping this pesky leak, hopefully without having to remove the engine once more?

Re: NC24 Bleeding oil. HELP
Have you checked to see if the oil is coming from further up?

Yes, I have checked where the oil is originating from. It seems that the oil is only seeping by the abovementioned seal.jedidude04 wrote:Have you checked to see if the oil is coming from further up?

Re: NC24 Bleeding oil. HELP
I did use black rtv to seal an oil leak before, maybe as a temporary fix? Is your output shaft straight and not bent?

Thank you for the advice. I'm don't believe that my output shaft is bent, but will check it if the problem persists.jedidude04 wrote:I did use black rtv to seal an oil leak before, maybe as a temporary fix? Is your output shaft straight and not bent?

Re: NC24 Bleeding oil. HELP
You might have a groove worn into the shaft where the seal sits.

Re: NC24 leaking oil. HELP
Is it a genuine seal?
Maybe it got damaged when it was installed.
As already mentioned the old seal might have worn a groove into the output shaft.
