603 Output Shaft Nut- 30mm 12 sided?
 

I need to replace the output shaft seal on my transmission and I don't have the right socket for the job.

I have a 25mm socket but it is not deep well and appears to be slightly too small anyhow. My guess was that the nut is a 27mm.

I found one thread here that states that the nut is a 30mm however it was not the same transmission as mine so I'm not sure.

Does anyone know what size socket I need for that output shaft nut?

Thanks!

Yes.

That's an area I haven't dealt with but a couple of tool specialty places might be able to help.

Thanks Sam.

Looks like it's $24.99...
