Default Maytag MAV 7700 transmission noise help
Model Number: MAV 7700   Brand: Maytag   Age: 5 - 10 years   

Appliance Parts from AppliancePartPros.com


Greetings,

My washer started to make a loud chattering noise this week during the spin cycle only. Everything else seems to be working properly. I tilted the washer up and took off the belt to inspect it, it seems to be ok. All the pulleys seem to spin freely, the transmission one has resistance turning it counterclockwise if that means anything.

I took of the dust cap & there seems to be about 1/2 a teaspoon of oil in it. I came to this forum and did some searching to get an idea or what to do next. Is there a way to narrow this done to a thrust bearing or the oil seal needs to be replaced?

I uploaded a quick video of the chattering sound if its of any help.

My washer was purchased April of 2001 so I understand the transmission is still under the 10 year warranty? I wouldn't mind having a repair done if the labor won't be too much considering the age of the washer. Or if Maytag supplies me the parts I wouldn't mind doing the repair if I don't need too many special tools.

I'll keep reading up on this forum for similar problems but if someone knows what my washers problem is & my next step I would be most appreciative.

Thanks!

Raul,

I could not download you video of the chattering noise??

But,

The noise is present in the spin cycle, and would not be from the transmission, as everything should be "locked up" and not moving.

After 8 to 9 years of usage, I would expect to see some oil in the dust cover cap.

Have you noticed if the clothes are more damp than usual when the spin cycle is through ?

I would have to think, you may have a clutch / brake slippage(thrust bearing) problem,

Something you may also want to try, when the noise is present, move the tub to several positions, and see if the noise disappears, you may have a warn snubber, causing the noise as well.

Good Luck,

Hey Joe,

Thanks for the reply. I put the washer back together and cleaned the belt & pulleys with some isopropyl alcohol. I ran a load of clothes through it and its not making any noises now

The clothes do not seem to be more damp than usual.

What I did notice though is maybe my brake has a problem? During the spin cycle when I open the lid the washer spins down slowly but doesn't stop right away like I believe it used to. I don't have any kids so other than a safety issue, does the brake need to be serviced? I really never open the lid during use but don't know if this is causing other problems?

I uploaded the video to youtube, it should open if you just click the link. I can try a different upload site if youtube isnt working for you.

Thanks for your help.

Based on what you've just told us,

I would reccomend a new belt, and thrust bearing kit.

Part number: AP4029079

Part number: AP4029079


Part number: AP4009132

Part number: AP4009132


The thrust bearing assembly, is responsible for driving the agitator, through the gears in the transmission , and holding the spin basket to keep it from moving,

It also, as a safety device, applies the brake to stop the tub when the lid is openned, or at the end of the cycle.

You're going to have to replace it, sooner or later, but you'll be OK for now, based on your explanation.

Ahh I see, thanks for the help. The noise did appear after a heavy load was run through the washer. I'll replace the belt & TB for good measure.

Raul,

Good idea,


That thrust bearing adjustment can be tricky,

Make sure you follow the instruction sheet, and be ready for some frustration.

Good Luck,

Hey Joe,

Just noticed the washer started making the noise again but now during the agitate cycle as well. Does this change anything or should I stick with the belt & thrust bearing kit change?

Thanks again

Raul

Raul,

Stick with the Belt and Thrust Bearing Kit,

They are still the most likely cause of your noise,

You may also want to check the motor pulley for excess play on the motor shaft, It's not a common problem, but a quick easy check.

(hold the motor shaft with a pair of pliers and turn the pulley back and forth, to see if there's movement on the splines).

Good Luck,

Joe,

I took off the belt & the drain pump pulley was making a scraping noise in either direction I turned it. Looks like the metal sleeve that the pulley is pressed onto is scraping on the base. I've heard this happens and that the pump has bought the farm.

I just ordered a new pump & the thrust bearing kit + belt. Hopefully the thrust bearing replacement fixes my brake issue.

Thanks for your help & time, I'll post up once my parts arrive how the repair went.

Sounds like you'll do it, and be fine afterwards,

Look forward to your update,
