snapped speedo sensor wires

[bigpino]

I broke my speedo sensor wires (915) right at the sensor it self. So there is no piece left to soldier iron the wire on. Is there a way to repair it? How do you get the sensor out of the casing anyway?

Welcome to the board. Where are you located (put it in your profile) and I'll send you another sensor.
I bought a new one when I couldn't find mine (it's a long story).

The sensor is normally held in place by a retaining clip/fork that is bolted to the case with an Allen bolt ... in that really, really badly corroded hole above the sender in your pic. Getting your sensor out may be a real serious challenge with the corrosion present I see ... you might try 9% pickling vinegar applied with a toothbrush ... allow to soak for five minutes at a time. Rinse off with plenty of water.

Take a small screw driver and try and pry it out if tht does not work you may have to just dig it out in pieces, hack away at it. Make sure you clean the pocket out before installing the new one, Try a wire brush and the solution mentioned by Early S Man good luck

x2, this is exactly what I had to do when mine failed, break it up gradually with screwdriver/hammer etc.

Good luck

Many thanks for your offer Chris, but I'm located in Holland. I guess you got a nice spare one. I have the same problem with me cv drive shafts. No idea where they are at the moment, hope to find them though.

Thanks Warren and Tab(?) I got it out. I just pulled it on the two 'handles' that stick out. Afterwards, I've pried out the white stuff. Was tricky since that stuff surrounds the wires (see print in white stuff next to the sensor). I tested the sensor with a magnet and it's still functional. Now I can soldier two wires to it and fixate it with that white stuff. However, I don't know what that stuff is. Anybody?

Looks like silicone sealant to me ... and I bet some of the kind rated for water exposure would work fine!

NASA and military contractors have used a similar-looking product since the 1960s to seal electronics, and it worked just fine on the Apollo 13 mission!

Though I am quite sure it doesn't meet, and hasn't been tested to the same mil-specs ... GE Tub & Tile silicone sealant would work just fine! $5 a tube is a lot easier to handle than $180 per tube, too!

[bigpino]

Indeed, water resistance is the one of the properties you need. I'm more concerted about the temperature. The original stuff was as hard as ceramics. Can silicon sealant cope with that?

Early_S_Man, what is "GE Tub & Tile silicone sealant" normally for and in what kind of store should it be available?

It's silicone used to seal around a bathtub! Any home improvement or hardware store (and maybe even places like WalMart and Target) should have it.

Really, that's great. How about heat resistance? Trannies get awfully hot right?

Does anybody have a picture of what the clip looks like that holds the sensor, it seems I'm missing mine but I know I have it somewhere, just don't know what to look for! A pic would be great!

Should I also use some kind of epoxy along with the clip to hold the sensor? Sorry for the hijack, unsolicited bump

If you're concerned about heat, go to your local Autozone or Pep Boys. They have high temp silicone.

I'll try that thanks guys.

Scottb, it's in the parts diagram:
