Product review (5 stars): Fits perfectly.
Fit perfectly. There are clutches out now that have 6 pads instead of just the three.  I assume they would last longer.

If your washer is not spinning always check the lid switch first.  Let the machine reach the spin cycle by starting at the rinse cycle (don't start in spin).  If nothing happens when it gets to spin, try again, this time with the lid up and a pencil or other non-conductive object holding the switch down.  If it doesn't spin this time, release the lid switch then activate it again.  If you hear a clunk, the washer is trying to go to spin mode - and the switch is probably OK.  If it spins properly this time, the switch is OK and the timer is probably bad.  If it doesn't spin, give the tank a little circular push in the clockwise direction.  If it won't move, it's probably the timer.  If it starts to spin slowly, or slowly then stop, or slowly and up to speed, then it's probably the clutch or the coupler.  (Also, if it spins on light loads but doesn't spin on heavy loads, it's probably clutch or coupler.)

Here is one way to check the clutch:  When it gets to the spin cycle and you can hear the motor running, give the tank a little clockwise push.  If it seems to go a while - or even gets going fast - then CAREFULLY, and with a glove on, try to stop the tank by putting your hand lightly on the top part of the tank.  Don't try to grab it and stop it - you could break, sprain, dislocate a wrist.  If you can slow it down pretty easily or stop it altogether, it's probably the clutch ($15) or the coupler ($5).  Look under the washer.  If there's black rubber residue, it's the coupler.  If there's no residue, or worse, some grease, then it's the clutch.  BUT - the grease comes from the transmission.  Read on.  If you can't turn the tank at all - and you're sure it's in the spin cycle - it's probably the timer ($100) not putting it in spin mode.  You can test this by turning the machine off then back on when in spin mode.  If it spins up to speed, then it's not the clutch or coupler.  .

If the clutch pads are NOT worn out, but the clutch is greasy, you might clean the clutch ($0)  - remove all oil residue on the clutch and the parts that hold it in - and reinstall it.  You'll have to decide whether you want to replace the transmission.  That's only $150 and it's a relatively simple job for a good DIYer.  But if you don't replace the transmission you may or may not get grease back within a year or two.  (I don't see where there is a top seal for this transmission.  That would be the least expensive option.)
