SUJET :

Hello,

thanks for having this forum. I am trying to do some maintenance on the shaft which requires the shaft seal to be replaced.
Does anyone have information on what part number is required and where I may find it?

Thanks in advance,
Ermal

what engine do you have? 

what is the diameter of the shaft?

for example this is mine its a volvo 2003 with 25mm propeller shaft 
volvo

 

I have a Yanma4 4JH! 

I have to go and measure it (its a bit of long flight for me) hence asking if anyone else has similar configuration.
