Lycoming 320 cylinder temperature sender
 

Anyone know how I can remove a cylinder temperatre sender unit from no 3 cyclinder on a lycoming 320. It is on the bottom of the head and there is no obvious nut that can be seen, It appears to be spring loaded, i.e. I can pull it out approx 1/8 inch on a spring.

CHT probe removal
 

Hi. The CHT probe is most likely the sprung-loaded bayonet type. Push it fully home, turn it as far as possible with your fingers anti-clockwise, and then withdraw.

Hope this helps.
