George or others, please give me the part number for the above seal. Un fortunately my engine manual is at the hangar, 25 miles away and I need to get the part number so I can give it to the alternator repair shop & they can get one to install in the tach drive.

Is there any better way to look up old posts that (in this case would have this part # listed) other than to go back through multiple prior posts hoping to find the right one?

thanks in advance :

"Generator/Alternator Garlock (spindle oil seal) Tach Drive"

I think you are refering to part annotated in the C-145 , O-300 Service Parts Catalog as number 21163 Seal, Tachometer Drive Housing, Oil.

Frank, I saw you at the Tehachapi convention. I saw you at the maintenance seminar. Therefore I know you have the 170 Service Manual, Electrical Systems manual. If you look on page 5, at the second paragraph from the bottom (the "Caution" paragraph)...you'll see where I recommended replacing that seal when replacing the generator. (And I gave the part numbers whenever possible throughout that manual when I addressed such items. It's listed there, ... PN 642714).

Thanks to all who responded.

Yes George, I have the electrical system manual---at the hangar, not here at the house. However had I been at the hangar and wanting to find the part number I most likely would not have thought to have looked in the electrical system manual. Now that you mention it I see the connection between the generator/alternator (electrical system) and the tach drive , but normally I would not have associated the two together since the only relation they have to one another happens to be the gasket and I suppose the drain galley to return the oil back to the sump. I would have come nearer looking in the 0-300 overhaul manual, but alas it is at the hangar too.

Awww...I still wouldn't have wanted to miss an opportunity to needle you. (....and the title of this thread is ...????)

George, PMI but what is the "170 Service Manual"?
