Replaced coupler in washing machine now has burning smell
« on: September 27, 2008, 06:29:41 PM »

Replaced coupler in washing machine because it wasn't agitating and spinning.  Both work fine now.  After a few minutes turning it on, there's a burning smell.  Both the clips holding the motor are slightly bent.  I wonder if it's hitting the motor or if the clips are too close.  Or I don't know if I hit some wires?

Remove the cabinet and check the motor coupler again.

Thanks, I will check it out and report back.

Forgot to mention, the smell is like electrical.  Noticed it few minutes after it was agitating.  I also tried to get some of the black dust off the motor.

When you replace the coupling you have to be carefull not to bind it too far up against the transmission. They make a special tool for 10 bucks to install the ends correctly. All I do is use a nut driver handle and that helps put the coupling flush but it does not bind up the transmission. I know because I have done it. If you have it too loose then it will simply grind off half of the plastic and stop spinning but it will wash fine. If you pound it in there too tight then it will bind up the transmission and impede the motor. BTDT been there Done that!

Thanks, I thought I had it up too far.  It turns out it wasn't flushed with the shafts which is probably why I had a tough time putting back the motor.  I managed to get one on the motor yesterday, but I'm having a more difficult time putting the other coupling on the transmission.  I'm using a nut driver and don't want to hit it too hard.  Is there anyway to make it go in easier?  Grease, oil, or whatever?  The coupling is a generic brand.  Seems harder to install than the oem.

The black rubber thing is worn out.  I was referring to the white plastic part.  It looks only halfway in.  Tapping it for an hour, looks like it hasn't moved much.

I had a broken coupler on my Whirlpool as well, so I replaced it yesterday. During the spin cycle, I too smelled a burning smell.

Does this happen because the two white pieces (with three prongs) have been driven too far onto the shafts of the motor and transmission sides? Is that what you guys mean by the coupling binding too far up against the transmission?

The plastic couplers look to be a bit improved from the replacement one I took off, because it has a metal ring in the center now. I will try JWWebster's idea to use the old black rubber ring (which is still intact). And how were you using the nut driver handle to get it on just right?

I was all prepared to go buy some 80w90 gear oil, because I also lost some oil before I fixed this because I had the washer upside down on its tub for 2 days to get easier access to it. I guess the oil slowly leaks out of the gear box. I thought that was the reason for the smell, but maybe it's the coupler. I will try repositioning the coupler first.

Thanks,
Chris

Installation is much easier on the white coupler part if you take a 1/2" deep socket and tap it over the center of the piece. You can pound away and get the coupler on the shaft really quickly. The smell will go away after a couple of loads anyway.

you want the end pieces to be flush with the shafts on bothe the motor and the tranny. if you get the endpieces too far on either one then you will have binding.

Thanks I will try that tomorrow.  I was afraid if I hit it too hard, it'll break the transmission or something else.

I also bought a new coupler with the metal ring in the center.  It went on very hard and I didn't have it flush.  I wondered why the motor clips went back on so hard the first time.  The black rubber peice moves freely now, and it didn't move at all the first time.  I just took it off and put it on again, we'll see how it goes.  I guess not having them on far enough is just as bad.  Thank you for the information, thought I needed to replace my transmision or something else.

Actually I used to sell a special tool for coupling installation for 10 bucks. It looked just like that black center piece but it had a square hole in it to fit a 3/8ths drive socket extention into and it was made of rigid plasic. You would fit an end piece on it and install the endpiece without the possibility of going to far and it was much easier to install the end piece. Nobody wanted to pay the 10 bucks for the tool. Didn't sell too many. Never reordered em.

I use a nice piece of 5/8ths shaft I saved from replacing a shaft on a belt driven blower.

yes, tapping the two couplings with metal piece flush against each shaft does the trick. i also just put them on without taping them flush first, after clipping the motor on, i tried to turn the shaft by hand, pushing on the black piece of the coupler. it was definitely harder. seems that if u dont flush the end couplers to the shafts, it "smashes" the black rubber piece and makes the diameter "bigger" which then seems like it hits the sides of the housing when its turning. its worse if the motor is not fully centered. after taping the white coupler pieces flush to shaft. (it doesnt take alot of effort). now the black rubber piece is no longer "smashed" and the motor went together without forcing it... you definitely want to tap the white plastic couplers against flush with the shafts on both pieces!!! NO MORE SMELL, THANKS ALL!! for this thread, helped me

I use the end of my hub wrench for Whirlpools if I don't have my 12" long 3/8 Drive Extension with a 1/2" Deep Socket handy. Works perfectly.
