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
LUBRICATION SYSTEM
The turbo unit is pressure-lubricated from the main engine oil gallery. A check valve is installed on the outlet o' the engine main oil gallery to stop oil flow to the turbo unit when the engine is not running. A scavenging pump rotor is equipped behind the original oil pump rotor to retrieve the oil from the turbo unit, ensuring a constant flow of oil.
Check valve opening pressure: 24.5 kPa (0.25 kg/cm , 3.56 psi)
