Product review (4 stars): Smaller length than the original but all sources confirm correct part
Update from March 2017: the drum bearings are super noisy 18 months after installing the new shorter belt. It seems to be a common failure for this product line from web search results but it is impossible to definitively correlate the cause to the tighter belt with available data. I am not sure what alternative there is, but beware that it may be a cause of premature failure.

Original review: I did confirm that this is the current replacement belt part for my MAH4000 Maytag washer.  You will notice the new belt is much tighter, and I'm giving it only 4 stars because the fit is too tight for me to feel warm and fuzzy about it.  I expect that the extra strain between the drum and the motor will increase wear on the bearings at one or both points.  The motor is particularly worrisome since the shaft protrudes a few inches to the pulley.

The original belt was labelled 62706950 and is nominally 54" long.  The belt in this kit is 6722870 with nominal length of 52 5/8".  It's a tight fit but it seems to work fine in the couple of weeks since I changed the along with the upgraded motor kit due to 2 phases having failed on the original motor.  I will update if there is some premature failure as experienced by some other reviewers.
