Since Maytag's Power-fin agitator and the Dependable Drive transmission 63 OPM speed is increased to 77 OPM using the 50 Hz motor pulley, and is not recommended because it's too aggressive and will wear-out your clothes faster over time, why not INTERCHANGE "intermediate gears"?

Replace the 63 OPM intermediate gear that has the "TRIANGLE" cut-outs...

with the original style 54 OPM intermediate gear that have the "O" cut-outs...pic no.2

The 54 OPM, agitating stroke can increase up to approximately (68 OPM) which is not that bad...same speeds as the early belt-drive Whirlpool and Kenmore washers...a little "easier" on the clothes---a little is better nothing...And, there's that 756 RPM FASTER SPIN!!! the 50 Hz pulley wonderfully provides

What do you guys think?

I was wondering how long it would take for this to be discovered here. The combo nets 67.5 OPM's.

Additional Option: Swap 63 OPM gearing in pre '66 machines with a powerfin for better washing, less wear on clothing, and MUCH less wear and tear on the porcelain tub.

Great to see your handle pop up, Dan!

Good Idea Harry

But as Dan noted it has been done before.


Another way to improve these MT washers is to change the agitator all together as the Power-Finn agitator was never a great idea and Maytag finely ditched it on their own.


There is a video somewhere on this site of my friend Bobs A806 with the 50 cycle pulley washing with a late 60s Kenmore roto-swril agitator and it is simply amazing how well these washers could have worked without the excessive clothing wear.

I have to agree, a RotoSwirl agitator is very effective in a Maytag versus that Powerfin…

it should have been designed with one from the start...

Thanks guys, like I said I'm not a mechanic/repair guy so I really rely on your years of experience, expertise, wisdom and guidance...greatly appreciated by the way...I have a ton of ideas and DIY'ers in mind but, do not have hands on access like all/most of you...forgive my ZILLIONS of questions, please don't get annoyed just remember I'm always learning and figuring things for the combo, still searching for next daily driver DIY'er which is the Maytag LAT9806...but will need a Dependable (PITMAN) Drive trans...the 54 OPM intermediate gear and 50 Hz pulley and belts set

...btw, If Maytag made their deep tubs WIDER with a rounder (BOWL)-like shape at the bottom of the inner tub roll-over would be much better for the shape of the Power-fin

Maytag 50 Cycle videos

Great videos, you can really see how superior the Load-Sensor agitator is, it turns over very well yet does not wear the crap out of your clothing, CRs was right on the money when they said that the two-piece auger agitators were the best thing that happened to top load washers in over 30 years  when they hit the seen.


If MT had used a 50 cycle pulley in orignal production of their washers they could have had a much better performing washer instead of just a mediocre machine that did not work as well as about any other US TL washer.

I wonder if after the Power Fin agitator was introduced any Maytag service people installed the 50 cycle kits on their machines or even installed the Power Fin agitators and left the original power train.

I'm looking for 'spares' or 'spared' Pitman 'Dependable Drive' (long stroke) transmission and 54 OPM Intermediate and Pitman gears for my (as soon I find) next Maytag Dependable Care Plus DIY'er

curious as to WHY?

why increase the speed using the 50hz pulley......only to slow it back down by changing the gears inside the transmission.....

seems like your going backwards...

if 63opm was aggressive from the start with a regular pulley that would be one thing.....the 50hz gives it the kick it always needed, especially with the larger capacity tub...

at that point, select Gentle speed agitation if you need to kick a 50hz agitation down...

FYI, the *shape* of the cutouts (triangle vs circle) is NOT a definitive way to identify the gear ratio - you have to go by shape and pattern. Gears were made with circular cutouts that have the same tooth counts as your triangular set.

Here are three example photos.
The first two are from a pair of threads (same user, different forums) rebuilding an A112 transmission from 1986. The second is a set of separate replacement gears.

I don't know much more than that, but just wanted to make sure that someone didn't buy them by accident just based on the cutout shape, and be disappointed when after all of that work, their agitation speed was the same!

Thanks for sharing (lowefficiency), as far as the gear and gears are concerned, refer to photo 2 of 2 at my beginning post...also, take a look at what (qsd-dan) Dan shared...he constructed my 'idea' can see it in his YouTube "Modified Maytag Mayhem" video...50 Hz motor pulley set and interchange intermediate and pitman gears that produced an AWESOME modified re-design...end result, much, much faster '756 RPM' HIGH-SPEED spin and a little-increased agitating speed from 63 to '67.5 OPM'...that's it
