I'd like to put a CHT (Aircraft Spruce, most likely) on my engine, but it seems the spark plug location requires either some grinding of metal, which requires removing a bunch of stuff, that requires removing the engine, etc...
Is there another place to install a CHT? There is a CHT sensor on the engine, but doesn't that have to stay? Or, can I attach a gauge to that one? The only alternative I was able to find was this thread (thanks 76-914) about bending the wire 90 degrees on the spark plug install option: "Like Mark said it's just a piece of metal so open it up a bit so that the plug rotates freely in the ring. Then with the ring on the plug bend it 90 degress. Now turn the plug again to be sure that it rotates freely after the bend. Insert plug into #3 with the wire at the 9 o'clock position (or towards the rear) and tighten. There seems to be a bit more room for the lead when installed in this position. at least my head had a bit more room to the left side of the plug. BTW, I left the plug washer on so I would not twist the sender." |

Barefoot,
Thank you for the helpful photos. This is something I need to do. The photos show a metal clip locating the sensor wire to a cooling fin. Could you say where you obtained this clip or how you made it? Thanks. |

I'm thinking where to bring the TC leads out thru the top tins, will need some small grommets which you can now get at Lowes or Home depot. |
