Machine would start to spin and shut off.
I removed the front cover to gain access to the motor. I saw that the belt was starting to get chewed up so I removed it. While looking at the schematic on Parts.com I noticed the Idler Pulley Wheel was much larger then one currently on the machine. I ordered that also in case I needed it. I needed it. Once I replaced the belt and the pulley the machine ran better then ever. Originally I thought I just needed the belt but thanks to Parts.com I realized I needed a little more. Thanks.

Idler pully seperated from bushing
first I unplugged the electrical plug then I removed the lower covet by taking out the 5/16 screws. I then took out the 5/16 screws that hold the top part of the front cover and removed it.
I then worked the belt off the aggitator pully and removed the hoses from the pump. I then used a 1/2 in soclet on long extension th remove the four bolts that hold the motor and pump assembly. I then worked the assembly out of the cabinate and using a long #20 torx bit I removed the pumfrom the housing. I removed the belt, then I removed the housing off the motor and replaced the Idler bracket with the idler pully. I then re-assembled it in the reverse of taking it apart. Works great with the new idler and belt.

Squeak and slight burning smell during spin cycle.
I took off the lower front panel and “watched” with a flashlight during the spin cycle. I could see that the idler pulley was intermittently stopping and starting. The back of the drive belt was also worn in the center. When the idler pulley was moving, it squeaked, when it didn’t, the friction wore the belt and made the smell.

To replace the Idler Pulley Wheel:
1. Take off the lower and upper front panels to access the motor assembly.
2. Remove motor by loosening four bolts.
3. Remove spring that applies tension to the idler pulley.
4. Remove the electrical connector by squeezing the plastic tab on top.
5. Remove hoses by gripping clamps with pliers (put down rags first to catch water)
6. Unhook belt from tub pulley
7. Remove 1 cabinet spring to make it easier to remove motor
8. Remove motor.
9. Remove allen screws holding the pump to the motor
10. Remove the pump and belt (take note of the location of the belt before removing).
11. Remove retaining ring to replace Idler Pulley Wheel (this was probably the trickiest part; I used a very tiny needle nose pliers and straight screwdriver).
12. Replace the washers on either side of the Idler Pulley Wheel as well as the retaining ring.
13. Replace belt.
14. Reassemble in reverse order.
15. Be thankful for the money you saved on a service call.

Washe would not spin clothes or agitate well
Pulled motor, as the belt will not come off unless you take to water pump off off the motor. Installed new idler wheel, washers, clips and belt. Reinstalled motor.
Works good and hopefully lasts a long time!

Washer would not spin or aggitate
(UNPLUG APPLIANCE FIRST! )Used large flat bladed screwdriver to remove tub damper springs on front of tub.Then remomoved washer pump hoses after placing towel underneath to catch waste water.
Removed four bolts holding motor and pump assembly to tub pulled it forward slightly to remove motor electrical connector, turned assembly over to remove pump ("torx bit")
Intalled new belt being mindful of routing and idler pulley. Seems new belt is slightly longer requiring a little tension spring adjustment might have to replace it also. Washer now functions properly!

Idler Pulley Wheel wasn't turning, causing belt to crack up due to heat build
Remove bottom and top front panel to access motor. Remove motor by loosening four bolts. Remove spring that applies pressure to the Idler pulley wheel. Pull out electrical connector by pressing on the tab on top. Remove rubber hoses by gripping clamps with pliers. Unhook belt from pulley at bottom of tub. Pull out motor. Push upward and inward the top of the tub to make pulling out the motor easier. Remove allen screws that secure the plastic pump housing so you can remove the belt. Replace belt. Remove retaining ring to replace Idler Pulley Wheel, remember to order replacement washers, mine was brittle and disintegrated so had to remove the second one from the bottom and used only one each side, seems to work fine. Reassemble everything in reverse order. It now purrs like a kitten, wife is now happy doing the laundry, I get to ride my motorcycle this weekend at the Los Angeles Crest Highway carving the canyons, whoohoo! Life is good.

I found the plastic pulley had fallen off the metal sleeving. Will just putting it back on fix the pulley? Does the metal shaft need lubricating?
For model number SAV3655AWW Maytag

Hello Mark, Thank you for the question. If the Plastic Pulley fell off the Metal sleeve it will need to be replaced as they are not suppose to come part. Hope this helps!

Spin speed builds then a little snap and it slows and starts to build again. Pumps and agitates fine.
For model number SAV5910EWW
PartSelect logo
Hi Jeff, thank you for your question. I would suggest taking a look at your pulley wheel and idler arm. You may also want to take a look at the belt as well. If those parts are fine then it may be the motor that is the issue. I hope that helps. Good luck with your repair.

I replaced the belt. The washer agitates but doesn’t spin. The pulley wheel is rough on one side so I am considering replacing that. Is there anything else I should be checking. I can manually spin the agitator and the spin on the machine.
For model number DLW330RAW

Hello Andrew, Thank you for the question. We also suggest checking the Idler Pulley Spring, Idler Lever, Spin Pulley for Transmission Drive and the Brake Rotor Assembly. We hope this helps!

Agitates and pumps fine, but spins slower than normal at full speed spin setting. I replaced the belt and idler pulley but it is still slow. Clothes come out wet enough i can wring water out by hand. Any ideas?
For model number SAV4655EWW
PartSelect logo
Hello Brian, Thank you for your inquiry. We would recommend checking the following parts to fix your issue: transmission, bearings, triple lip seal and hub kit, drain pump, drain hose, and timer. You can test the parts with a multimeter. If you are unfamiliar with how a multimeter functions, there are YouTube videos available to assist you. Hope this helps!
