Product review (5 stars): Works for Whirlpool LER4634JQ1 (barely)
This is supposed to be universal, but it cuts the limit pretty close.  I read another review on here from a Whirlpool owner who had problems with the tension pulley touching the pulley on the belt motor.  I was a bit concerned about that same thing once I threw everything together.  Thankfully, the tensioner missed the drive pulley by about an inch... which is still close enough to make me nervous.  But I played around with it until I was satisfied that it wouldn't be an issue, threw everything back together, and fired her up.  Works like a dream!

I'm really happy this worked out.  I needed to replace the belt and didn't want to continue using the worn slide plate that served as the factory tensioner.  I also saved myself a grip load of money buying this kit on Amazon.  To anyone concerned about whether or not this will fit a Whirlpool LER4634JQ1, never fear!  Just prepare to be a bit nervous about where the tension pulley ends up. :)
