Tach Question

[Skip]

I bought an old style 3 1/8 inch tach for my PA-12 with an O-320. Instead of being externally threaded on the back where the cable nut screws onto the tach this one is internally threaded. Has anyone ever seen this before.

Skip,

I do believe Keystone can make up a compatable tach cable for you.

Thanks John thats all I needed to know. The tach is in great shape so all I will need is a cable. Skip

There is a 90 degree adapter that installs on the tach that mates it to a stock cable.

I looked at that Steve and it won`t work but thanks for the thoughts anyway. I will need a cable that has a female threaded nut on one end and a male threaded nut on the other end. It`s a great tach and looks brand new I just need to make it work somehow. I have all of the other old gauges so I just needed this one.

The one I installed had an elbow adapter installed on it.

Was the tach housing female threaded, all of the elbow adapters I have seen have a male end and a female end I would need one with 2 male ends. Let me go back and check Aircraft Spruce and see if they have one I may have missed.

I will see if I have another one. I would call Lockhaven Airparts or Keystone.

I checked all of the usual suspects and all they have are 90 degree adapters with a male on one end and a female on the other and that won`t help. I am hoping Keystone can make a cable with a male nut on one end and a female on the other. If you have something that will work please let me know. Thanks Skip
