Temp sender removal …

[HillbillyGuy]

In an effort to get my temp gauge functioning …. Snap! Followed by bad words. Any suggestions on removing the remaining end of sender from motor? Tried easy out and stopped. Its in there snuggly. Going to try some kroil and soak and give it another try.

I don't know what you're working on but you try heating the block around the sensor. Maybe with a pencil torch.
I'd try a square type ez out.

Its the temperature sensor/sender that sends signal to temp gauge. I tested the wiring a gauge and they are good. Either the sender went bad or was not making contact ground enough. I will replace it once the remainder of the old one is out. I have square easy outs to try. I sprayed it down with kroil and letting it soak good. My guess is it built up some corrosion that had it kind stuck. It also appears the banana head who installed it may have tightened it too much.

Brass and aluminum do not play well together unless a barrier was added to the threads before install. Worse case scenario is the head might need removed to machine out the left overs. I would try heat then cold a few times to see if the corrosion can be broke loose. Good luck.....

Two ball peen hammers.
Put the small head on the “bolt” and smack the face of the hammer a couple of times with the other. Breaks loose the worst corrosion

Should be able to remove with easy out of proper size

I managed to get it out, but since the gasket has a very small leak, I am going to pull cover. This lets me confirm no lil pieces of crap fell down removing old temp sensor, and at the same time fix the small leak. I like your suggestion. Whoever put the old one in decided it needed to be gorilla tight.

So,,,, How did you get it out?

Square easy out and very carefully. It more ground it out than removed it. This is why I will pull the cover for a new gasket. It has a small leak anyway. This allows me to clean up the threaded hole for new sensor at the same time. I also get to see if any crap is inside the water ways. Just seems sensible to do all of this and not risk the chance of a plugged water jacket and potentially much bigger issues. Threads look decent and should clean up well. Since the end of the sensor is a hollow brass tube coving the end, I suspect the very end fell down in the water area. I do not want that chunk to wind up plugging up the water flow passages.

Great idea, but from the pic posted, I don't think there is a head left, appears the center is hollow where the heat sensor broke out. But I could be wrong, just looking at the pic.....

Correct! But I still like the idea and will log it in my vault for future use.

Don’t need a head…all you’re doing is “shocking” the interface between the screw on the base material to break loose the corrosion bond. Same mechanism as an impact gun.

The buddy that showed me the trick uses an air hammer instead of the hammers.

Removes the flat head screws used to retain rotors like magic.

Well would ya look at what I found laying all cute. Have to wait on new gasket to get here, but removing the cover was the correct choice. That is the end of the temp sensor circled.

Have used tour idea many times and it does work, but my concern is the fastener is brass and could easily be damaged by a sharp blow, or mashed where it couldn't be removed... if it were steel, I would agree fully.

Can you get the rest if the threaded portion removed ?

My largest customer is a copper, brass and bronze producer….

Brass and bronzes (copper alloys) are a lot tougher than you give them credit for. Think ammunition shell casings.,

Would be surprised if it’s actually brass. Brass (copper and zinc) doesn’t fair well in marine applications.,

Really , so why do they make so much marine stuff out of brass , like propeller ,rudder , rowlocks , fairlead ,cleats ,exhaust manifold screws that hold the boat together. I had all of these parts and more on one boat......to be fair it was a pile of crap and it filled up with rain water and the arse rotted out of it ........but all the brass bits were ok . Some were nickel plated
Brass bullet shells are fully supported by steel .....they could be made out of tupperware , or paper .....which they were

My guess and its only a guess, is most of these items are made of marine brass. Not typical 360 brass. I did not look at the part close enough. I am in replace mode.

Good point
I was buying stainless bolts screws etc and the girl at the shop...bla bla bla . I didnt know some stainless alloys are not so flash for salt water ,spose its logical brass might be the same .
