Air restriction sensor

[srecc]

Hello all,
I have a 1986 Gehl SL4625 SX that I am trying to get back to operational condition. Does anyone know how the airflow restriction sensor connect to the the air filter housing, I mean specifically, the threads on the attachment point are completely shot, I might be able to rethread but I doubt it. Essential what I'd like to know is would that simply be a threaded tube welded to the housing or is it more complex?

would something like a heli-coil work ? I would think it would if epoxyed in place and not a excessive amount of torque used on sensor.

Thanks for your reply but, no a helicoil would not work. The threads on the attachment point on the air filter housing, male threads, are kind of mashed. I don't what the previous owner was trying to do but the sensor is plastic with plastic threads, even the old one. I'm finding quite a bit of, f - it, cut it, we don't need it... very frikken annoying.

do you think it is a common thread? maybe figure out its size and pitch and just run a die over it to clean it up.

Thank-you, I thought that too. So far I haven't been able to, I used the new sensor to try determine the size and pitch, i think it may be metric, non of my sae fit. I don't have many metric taps & dies so my plan is take the sensor to the autostore and check it on their screw board thing. The other thing is and why I wanted to know if it's supposed to be an open hole, like a tube, or not, the whole stem is so beat up, if it's supposed be open, it is not currently.

I think it would have to have a reasonable size hole in it ,I believe that it reads the vaccuum that the restriction the air filter puts on the air intake. Telling you that a filter cleanout is overdue.

that makes perfect sense. I wish I could see what it is supposed to look like, mine looks like there's no hole but maybe a strict filter because the center of the threaded circle, so to speak, is different from the area around it.
