Product review (5 stars): Pretty good fit. seems small
I purchased the Whirlpool 12001788 Belt and Isolator Kit for Washer here because it was a pretty good price and I knew with prime, I'd have it in a few days, now a few weeks like some parts stores. This kit was a prefect fit, and easy to install. took less than twenty minutes. it was harder to move the washer from the stand than install the items. Belt was about an inch shorter, and a bit lighter in thickness. But it seems to be fine so far. Maybe the old one stretched quite a bit..
Now my wife is happy the washer runs quieter, and I'm happier it was a cheap fix.
