Tach cable

[hangarb7]

Still preparing for my first annual on N44057. Mechanic advised lubing the tach cable with graphite and to look for an O-ring when I disconnect it.

I disconnected it at the engine ('46 A65-8) but could see no O-ring. Is it on the tach end?

Also, should I remove the cable completely to lubricate it? Any suggestions on technique? Can I get the graphite at a NAPA store? (Of course, I would tell them that I have a '46 Buick or something....)

Re: Tach cable

Dunno about the o'ring. I don't remember one either.
Had a tach cable break twice with me. In '96. Then I found out the tach was freezing up. Replaced it and OK.
Sure wouldn't hurt to lube it. I disconnect the ends and use a spray oil. Could be difficult to use graphite.

Re: Tach cable

If you have a right-angle drive behind the instrument, lube this too.

[edited to add: the tacho housing in the accessory case has a regular oil seal, and a gasket under the outer flange...see photo. Photo actually shows seal in the wrong way round...d'oh!]
