Div 900 Shaft Breather Valve

[covertcodger]

On the shaft drive housing of my D9 I have broken the dome shaped cap off the Breather valve which sits at the top of the rear differential housing.

Question: Does this valve screw out? I am reluctant to put a pair of Stilsons on it until I am sure it is removable.

You sure it's a breather valve?

Jim, not a lot of help I know but, in the parts fische I have it doesn't look like it screws out , but it gives a part number for the complete breather assembly; 2H7-17590-00, so I assume it can be replaced separately?

Armed with this number I would suggest ringing Yamaha spares supplier and asking them?

Trev - I have it on very good authority that it is indeed a 'breather valve' ;D

Thanks for the Part Number. I shall have a word with my local Yamaha Dealer tomorrow.

Cheers mate.

NOW SORTED
