914World.com _ 914World Garage _ AA heads from LN

Posted by: cwpeden Oct 3 2023, 10:20 AM

Just got my new AA heads from LN and they don't have threaded holes for the HT Sensor.

Does anyone know what thread it is? Need to steal the gear from work to take of it at home.

If no one else comes in with definitive information, I'll measure my spare this evening and let you know.

10MM 1.0 ultra fine thread.

Sigh, sounds special.
Hope we have one in the machine shop.

That tap is not included in most sets… but I picked one up at Ace Hardware.

Here is a picture to give you the location from my 1.7 heads. About 1 inch on center from the bolt hole and it’s angled in.

Same thread size as the brake lines.

If I recall is an adaptor coupling you can get to install it in one of the tin screw holes.

I have pulled one off a motor before.
