Reference sensor

944 / 1 no start, no tach bounce. I am having trouble removing the reference sensor.  I suspect that it has been in there since 1984. Removed the retainer bolt, used a lot of wd-40 and have it twisting but it will not pull out. I suspect corrosion build up on the metal end of the sensor. Any ideas for pulling it out? Thanks in advance.

I would use PB Blaster, it seems to work better. I had the same issue and I grabbed some pliers and started rocking it back and forth while spraying PB Blaster. It took a day or two but was able to get it done. Hope this helps.

Thanks, I have been spraying it daily for a week or so. I guess  will try pulling it again later today. I may end up taking the entire bracket off ... speed sensor also. However I will then need to gap the sensor.

I twist it so that you have a tab to pry on.
Use a framing demo pry bar to pry up on it while pulling on it with some long nose pliers. The combined pull will usually get it out.

I always coat new sensors with grease and make sure the bore is clean with a 12Ga gun cleaning brush.
That way it slides right in and will come out easy for next time.

If it stays stuck, do a search on "vice grip slide hammer"
  

Dave - black 84 no longer exists. Sad 83 self destructed. All better now. Smiley
