Product review (5 stars): Clutch kit cures no spin Whirlpool washer.
This is an Amazon purchase, but was bought for me, by another Amazon shopper.  Always had to start the spin cycle by hand pushing the drum.  Clutch has been weak for a couple years.  This clutch was an exact fit.  Yes, it has 3 pads, but some complain that 6 pads are needed, however my original Whirlpool clutch has  3 pads, that were worn down to the rivets. Took about an hour to replace, and I was in no rush. Worse part about the job was trying to get the transmission off it's 3 mounting studs, and again, installing back on the mounting studs.  Also wasted time looking for the brake cam clip that flew away.  But overall it was a fun job.  Now the spin cycle is back, and slings the water out like it did when new.  You need a 3/8" rachet, extension, 7/16" socket, 1/2" socket , pair of Channel Lock pliers, flat screwdriver to do this.  Don't fear doing this job, check the you tube video for instructions.  This clutch kit fits Whirlpool model LSN1000QK.  If your washer does not spin out, or spins out too slow, you need this clutch. ......and some people are junking their washers, because of this simple $12 part, what a shame.  Thanks!

Update,  April 2018:  Clutch still works great.  I have to wonder about some of these people that complain the clutch is inferior junk. I tend to overload washer, but the clutch still spools up fast, and slings the water, so no need to replace my Whirlpool that was purchased in 2004.
