how bad did I just screw up?

[Brendann99]

Just got my freshly rebuilt engine back and was putting in the temp sensor and it snapped off and is stuck in there. Pic attached. Any chance I can just hook the wire to the part that is sticking out there or does this thing have to be torn apart again. I am seriously bummed right now.

 

[seadooya]

WOW!!!....THAT SUCKS. You gotta tear the motor out now, man...:banghead:

If anything, find a new head cover, if the wire wont work, connecting to the prong sticking up. or pull the head off, and grab with liers from the inside, and twist-er back out, and get new sensor.

 

[Brendann99]

Well the motor is not in the ski yet. it's just sitting on the garage floor. But I'll have to call the guy who rebuilt it and see if taking the head cover off will void the warranty or what. FML

 

[Brendann99]

Any thoughts on using an easy out? I've never tried it before. Anybody have any experience?

 

[Dr Honda]

I would pull the junk out of the center, and use an easy out. You know that part isn't seized into the head shell... so it should back out with out too many problems.

 

[Brendann99]

Easy out is a no go. Not as easy as I would have hoped. The temp sensor metal is so soft it just seems to tear it up and not pull it out. I'm thinking I'm just going to have to replace the whole cover and void my warranty. AWESOME!

 

[seadooya]

dont need to replace the "cover", remove it, and get sensor out, but if yuo wanna replace it, i got one, along with temp sensor.

WHo did rebuild?

 

[Brendann99]

Full Bore. I talked to them. He suggested drilling it out and using a helicoil. I'm personally not real comfortable doing that. But I'm considering it. On the other hand. How much for your cover and sensor?

 

[seadooya]

drilling it out.., yeah ok, then all that crap goes through the cooling system...:stupid:

Anyway, not to detour the "sale", but you need to remove the head, either way yuo look at it, might as well, give-ur a try, if you screw it up, hit me up then.

 

[Dr Honda]

I dont know how removing the head shell will void your warranty. That part comes off, and doesn't need a new gasket or anything. (mounted with O-rings) You can take it off... drill it out, or what ever, then bolt it back on.

FYI, the threads on the sender are tapered, so just make it snug. It won't tighten until it stops, like a bolt will.


The only other thing I would try is to use a left handed drill bit, and go slow. It may bite, and pull out the tip of the sender. Left handed drills aren't easy to find, but you can get them at any industrial supply house.

Take the head off and drill it out to the tap size (minor diameter). The threads in the head should be visible now.
Then take a dental pick and pull up what is left of the first sensor thread and carefully wind the threads out like a slinky with some needle nose pliers.

During this process you might flat top some of the internal threads, but it should be fine to screw in another sensor with plenty of teflon tape. Good luck

If you do what Jesse says, do not give in to the urge to reach down and grab those threads with your bare fingers.

Ask me how I know that...I worked in a machine shop for several years during college, and did that once. ONCE!!!

Yep...made my living doing this kind of stuff for the last 30 plus years.

 

[scooper77515]

Then you know what I mean...

I was sitting in front of a lathe for several hours. A pretty big lathe. And that pretty little curly-que of metal is peeling off, and it gets pretty long at times and doesn't want to fall into the bin.

I have gloves on, and been working 6-12s and a 10 on sundays for the past couple months straight, with an hour drive in and home.

So I am a little tired and not thinking with my full faculties.

So that snaky chunk of cork-screw steel is peeling off and getting long, longer, and nearly in my lap, so I just reach out to grab it and bend it a bit to make it snap.

Oh. SNAP. cut through my glove and half-way through my finger. :ack:

Use some sort of metal tool to grab those threads. Do NOT try to pry them out with a finger.

Good one Scoop,
LOL...I have scars all over my hands from that very thing. As I got older I made my cutting tools with a chip breaker, but the problem was, now these "circle 9" chips were flying everywhere including down my shirt. Those damn thing were hot too!!! LOL

Close the door on the lathe. :rofl: (modern tools are good)

Oh... and I only had to cut myself once... then I kept a pair of needle nose pliers at the control to pull stringers away from a tool.

In my day, if you had a lathe with doors, you were walking in tall cotton or kissing up to the boss.

 

[scooper77515]

doors? I don't think I have ever worked on one that was less than 75 years old.

We had to always back off and remeasure, then go forward just to take up the slack in all the gearing.

The 100" boring mill had .200s play in it, on a good day.

but, yes, I carried a set of needle-nose pliers and a long screwdriver around after that first mishap.

 

[Brendann99]

Back on topic. LOL On the o-ring between the cover and the cylinder head there is a red goo. What is this? Do I need to reapply when I put the cover back on?

you are right... sorry.


The red is a sealant of some kind... you can put them on dry if you want. The book recommends Loctite 515 if you feel more comfortable using a sealer.

 

[scooper77515]

What was that topic again?

Sorry to get it off topic. I will try to do better :cheers:

 

[Brendann99]

LOL. it's all good. I'm on to the next topic!

 

[onebadcav00]

a really sharp punch will work pretty good, just chip the brass- the sensor is brass- away from the threads. if you chip enough away it should break in half or loosen so you can un thread the rest out.

 

[drjones_xxx]

Have you tried stud extractors? there pretty good with this type of thing.
