Thread: Welding Arm to MonsterGuts Motor?

Tweet

Has anyone actually had the Arm piece that comes with a Monsterguts wiper motor, welded to the wiper motor?

My 'cocoon victim' prop stripped the little teeth out after only about 10 movements.
I tried filing in some teeth, and tightening the crap out of it, and that just led to to lock washer coming out, and the nut stripping.

So I want to go get the arm welded onto the motor directly if it's possibly.

I just was wondering if anyone has done this already, and knows if it will work. I'm not sure what kind of metal both pieces are, or what kind of problems the motor could have from the quick burst of intense heat from a welder.


Sucks, I was all excited about the movement I was getting during my little test run, then it died.

Look at it this way....you have nothing to lose, the motor isn't worth two cents the way it is, I don;t see any problems by welding it.

The problem you are having seems to be a fairly common problem with this motor and that is why I only use older wiper motors. Motors that was made before we started getting all of this cheap stuff from China. Actually I don't have a clue if that motor came from China but if someone can make a profit off of it by selling it for $15 It's has to be cheaply made and with cheap parts... China?

I hope you get it fixed. I know some people will use JB Weld to fix it, I would rather go with real welding.

seems like you may have too much load on this poor little motor if that is happening. probally you could have it brazed which is kindof a high heat soldering the metals are 2 different ones maybe mig welding would work. either way i hope you have a spare if it warps the shaft

The motor itself doesn't have much trouble moving the prop, but it is kind of a jerky motion, I think that's what stripped it. I figured this prop will probably only get a season or two before needing the motor replaced, but we shall see.

And I agree, I just didn't have any other old wiper motors laying around.

If it breaks, oh well, will try to redesign the prop a bit for next year.

Would a typical Exhaust Shop have a Mig Welder? I always get welder types confused, MIG, TIG, etc etc etc.... lol

I would take it to them and say...weld this, I'm sure they will tell you if they can't.

When you go into the shop let them know you do a free haunted display (or house if that's what you do) and the motor is used to move one of your props....not used in your car. In my experience people will do things for free or cheaper if they know the effort you put into the neighborhood kids having a great time on Halloween....and its for free.

You'll definitely want to have it MIG or arc welded. That will limit the amount of time it's exposed to high heat. A good tack should hold fine - you shouldn't have to have it welded all the way around.

Sounds good. Thanks everyone.
I figured I would just toss the guy who did it $10 or something.
They will know it's not for my car, as I don't think I will take the motor off the prop, it's strapped on there nice and straight, why mess with the part that isn't broke.

As an IT person, I am used to people abusing my skill set and expecting it to be free, so I always try to give people something when they do something for me, even if it's just 2 minutes to weld something.
