Default Cap for the tach-plug needed (I think...)

Hi.

I've a Superior IO-360 with dual P-mags and I think I need a cap plug.

The RPM-indicator get's it's tach signal via a wire from the P-mags (I think?) so the tachdrive-port on top of the aft side of the engine won't be need. ( I think)

Therefore I suspect I need a cap plug of some sort to screw on the tach plug? I mean; that tach plug needs some cover of some sort, right?

I've searched this forum but can't find some info on this?

Any idea where I can get a suitable cap plug?

Sorry for the possibly dumb question guys... (and gals....)

Thanks!

Default Doesn't have to be any particular cap.

There are cap plugs available, but they are only "dust" covers. The shaft has an internal oil seal. The cap is just to keep foreign matter out of the tach drive.

You need a tachometer drive cap. I believe Van's, Aircraft Spruce, and Avery tools all carry them. From Van's, it's part number: IE RC-1 CAP.

Thanks again!

Default Tach Drive Caps

Chief Aircraft sells one for $6.95.
Aircraft Spruce has one with four tabs so you can safetywire it wherever it happens to be convenient.......$19.95.

I ordered the one from Chief. It does the job.

I was given one of the Aircraft Spruce ones by the SOCAL group last fall - it is truly "Presentation Quality"....

Let's see - that money will buy a good six pack or a case of beer. Dust cover or beer, hmmm. My plane doesn't have a dust cover, hasn't for the last 800 or so hours. Beer was good.

Seriously, cover not needed.

It may not be needed, unless you removed the tach drive, as I did.

Even then, for the price of a good six pack, it is probably not a good idea to leave it open

You mean the whole thing, seal and all was removed? If so, that is a different issue altogether.
