I was at work the other day, handling some of our belts and I thought "Gee, that looks an awful lot like a Maytag drive belt." and it got me thinking. SO, Ive brought various machine belts to work and compared their size to what we have in inventory, and then measured the width and length of each belt and lo and behold, wouldnt you know it, but all of them were a match. A much cheaper match.


Maytags drive belt is a 4L390 (also known as a A37) and the pump belt is a 3L390.


GE Filter Flos use a 4L300 (also known as an A28)


And finally, the Whirlpool belt drive, non quiet pack, uses an AX47 belt.


SO, considering a 3L390 and 4L390 together are $17 Canadian versus $36 from Whirlpool, there may be some value in this.


Anyone else try this? What about Martin/Yogi with your super belt drive? What did you use for that?

Although the belts will probably fit, I suspect you will be disappointed with the results at least as far as the two belt Maytags are concerned. Unlike a typical v-belt, the Maytag belts were designed to slip, especially during spin. If the belt can't slip during the initial ramp up, the motor will overheat and trip off as it tries to bring a full load of clothes and a tub of water up to speed.

PepBoys, AutoZone, NAPA....are a valuable asset for replacement belts....not hard to match ones up, or even go wider... 1/4 the price of an OEM belt....

Clutch style belts can be found at Farm and Garden stores, same as used for riding mowers and such....

we have a shop here that has a catalog, for just about any style/type of belt there is...."V", cogged, flat, clutched....take the old one with you, and he can match it up...

Hey Jim, the 3L and 4L390s are identical to the Maytag belts. I brought a new set of Maytag belts to work and compared them, same texture profile and material. 


For your enhanced Kenmore Martin, what belt did you use? Im going to search tonight for the thread when I am at work to read for fun ha.
