Turbo Oil Leak sources

Submitted by Dave Jackson on Sat, 07/31/2010 - 04:24 
Hi all

Anyone in need of the main shaft seal for a Seca Turbo oil pump -

The seal is not listed by Yamaha as they only ever sold complete pumps which 
are now obsolete.

I have managed to track down what appears to be an identical seal as used in 
many Honda model oil pumps including the GL1800 Gold Wing.

The Honda part number is 91208-MN1-771 and the seal size is 11 x 15 x 3mm

If this seal has failed you will be getting oil flowing back to the turbo
