KENMORE MODEL 110.20842990 MAKES LOAD BANGING NOISE DURING SPIN CYCLE EVEN WHEN EMPTY. NOISE IS LOWER ON SOFT SPIN THAN ON FAST
This assumes that you have a basic Kenmore / Whirlpool top load, direct drive, neutral drain (it doesn't spin until the pump removes most of the water) machine.
First, see the Sears parts site for your washer:
and you'll see a list of major sub-components with diagrams and parts.
In order of difficulty, there are three possibilities.
1. It's possible that the Motor Coupler is worn / broken.
This is a three part plastic and rubber device that transmits power from the motor to the transmission. If it's worn and slipping you may hear the plastic pieces grinding against each other.
It's an easy repair.
See the following:
If the Coupler is worn, it's an easy and inexpensive fix.
Before going further, I'd check and verify that all the springs and vibration pads are in place.
See the following for where / how they attach.
2. It may be the clutch bands have worn.
See the following for how to remove the pump, motor and transmission. The clutch is on top of the transmission. Sears has replacement clutch bands.
You don't have to remove the drive tube and brake to change clutch bands.
3. If it isn't the motor coupler or clutch, it could be the "agitate cams" in the transmission.
These are plastic pieces that move the agitator drive shaft up about 1/4" when the washer goes into the spin cycle. If they are worn, you may hear a grinding noise.
Also see the Whirlpool / Kenmore service manual for top load direct drive washers.
See also a more detailed description from Whirlpool of how their transmissions work.
Remove the cabinet, pump, motor and transmission. YOU DON'T HAVE TO REMOVE THE AGITATORS OR TUB.
I had the same problem with major gear grinding during the spin cycle and this solved it.
The agitator cam and follower use the same whirlpool part number 62580/01. This is a plastic set used to raise the agitate gear on the shaft.
Pull the transmission.
Remove the clutch (the spring holding the clutch to the spin pinion is a bear to replace.
Remove the 8 transmission screws carefully, the transmission is full (15 oz.) of 80-90 weight gear oil.
Remove the transmission cover.
Pull off the spin pinion.
Push down on the agitate spring and remove the spring clip. Note where is attaches to the main shaft.
The two plastic agitate cam parts pull right off. Don't lose the washer on top of the cams.
Replace the cams, washer, spring and clip, pinion, oil (assuming you drained the oil first), cover and clutch parts.
Line up the transmission so that the release cam on the brake drum will snap onto the clutch spring retaining clip and put all parts back in the washer.
The basic tools are screwdriver, small socket set with up to a 1/2" socket, vice grips or good pliers (to remove and replace clips)
Be sure to align the holes on the Motor Coupler correctly or the motor and transmission won't fit together correctly.
Following is also the Whirlpool parts list for their commercial top load direct drive washers that has a better description of the cams and the Whirlpool part numbers.
It is a bit of a messy job but much ($10 vs $170 for a transmission) less than having a service person replace the transmission.
Be sure to study the Service manual so that you can see exactly how the cams work.Also see the Whirlpool / Kenmore service manual for top load direct drive washers.
