I need some more brains on this one.

So short story long my y harness got caught up in my spur and a chunk of something is stuck on the spur gear I thought it was just solder but after a couple of minutes under the torche with a few strands of the wire glowing red this glob of stuff still didn't want to come off. Any thoughts or just time for a new spur?

What is that!?

Difficult to tell.. melted nylon with wires mixed in?
And, did you break off a tooth off that spur?? Looks like something is missing at that area..

Agreed, need to take a wire brush or something to it to get the mechanical growth off to see what we're working with

If thats a 50t i have one from my typhon ill mail it no cost when i find it

It looks like solder and wire melted together. I think the current caused the wire to weld itself to the spur.......... All the teeth are there.

Yes it is. And dude that is awesome thanks.

& a 46t to make sure that never happens again!! 5mm?

Looks like a ball bearing and grass..

Probably when you tore the wire open it shorted out, pulled a tons of amps and yep basically soldered/welded. That metal spur basically looks like you took a torch to it.

Kind of cool if you think about it. But sucks for you.

I’d buy a new spur gear, but still try to save the current one as the other teeth like pretty good. You said the torch didn’t work, but does it as hot as your soldering iron? Maybe with a file/dremel you can grind that blob off.

 

[Camaroboy383]

Grab a small flat head and a hammer and pop it it off.. any residual can be cleaned up with a triangle file.. easy peasy..

Hopefully the Bec didn't take a hit from the short..

Or mash on the throttle, works for me nearly half the time

Found it

Is your battery OK? Sucker shorted out and started arc welding the spur gear.

There are strands of wire sticking out of the glob they got red hot, my soldering iron can't get wire red hot.

I might have to try that and get a triangle file.

Oh gosh I never even thought about that.

It looks okay. I haven't checked the ir yet though.

 

[Doom!]

I gotta say, I am impressed at the cool problems you guys come up with! I was gonna recommend what @Camaroboy383 said. I think a good sharp tap or two should pop that mess free.

 

[Diem Turner]

It sounds like that blob and the wires got proper welded to the gear by arcing.

 

[slick2500]

It's just a big glob of melted copper. I need to get some small files to get down into the teeth.

 

[Senton_Prime]

Just my opinion but I doubt it can be salvaged.. enough heat/energy was generated to fuse the copper to the steel!! Hope u can though!!

No the teeth are chipped under the glob of crap. At least they looked chipped.

Yeah.. definitely a dead short arc weld.. like dropping a wrench across a car battery.. yikes!..

It can be cleaned up with a file for sure.. but man, it might not be worth it, time over cost type deal...

But if you do clean it up, definitely make sure to very carefully inspect those couple teeth as they mesh with the pinion..

An arc weld like that can do several things.. one of them pooling the steel for a brief second leaving the area bulbous..

So don't be to surprised if you find some high spots in the steel itself near, or at that arc site.. of course you will need a little extra elbow grease to true that steel up if that is the case..


Were you able to get power back to that esc yet? Very curious if it still functions.. I hope it does man .
