Product review (4 stars): Perfect Fit for Maytag Neptune.
Perfect fit for Maytag Neptune MAH5500BWW washer.  Whirlpool branded pump made by Plaset (same as original pump).  Four stars only because this new one was made in China (original Plaset made in Italy).  Original made it 15 years before failing...fingers crossed that  moving the mfg to China hasn't hurt quality.
