I recently read other post talking about Ametek Big boys. My family owns a laundromat with one of these old machines in it. It has been out of order for the last few years due to bad bearings, water leaks, and electrical problems. We finally decided to remove the machine from the laundromt and take it to our shop in an attempt to repair it. We were actually able to locate the bearings, seals, and a few other misc parts at a local auto parts store. We have to get one more final part and it should be here tommorow. I'll post some pictures of the repair process and hopefully a video of it working after its back in operation.

It looks like there are 2 drive motors judging from the "bump" for the capacitors. One looks to have the clutch mounted on the front. Is it one motor for wash and one for spin?

Boy oh Boy, I remember the local laundromat near where I live use to have 3 of them and it use to cost a 1.00 per load. Those machines hold alot of laundry and were used a quite often. You can wash a 9 x 12 rug in those machines. Good to see you will be getting it back in action again. Good Luck

Thanks for the feedback & good luck wishes guys. Yes you're right there is one motor for wash and another for spin. No clutch though, just pullys. The wash motor is on the left, and the spin motor is on the right. The spin motor has a double pully that runs the drum, and a larger pully (the one visible in the picture) that connects to the wash motor. Years ago the price was 1.50. Last time it was in working order the price was 2.25. Probably will raise the price when the big boy gets put back down there.

Two Motors

launderess's profile picture
Common arragement in many older (and modern for all I know)front loaders made in Europe.

My Miele w1070 has two motors; one controls wash action the other spin. Thing is built as one unit and weighs a ton.

If you truly plan on returning that washer to service, contact Amtetek or your local serviceman/parts place for an updated door lock system, assuming yours does not have it already.

One big reason Ametek discontinued it's laundry division was they were sued because a person was able to open the door of one of their machines whilst the tub was still moving. He lost an entire arm IIRC, and got a nice big award against the company. One result is that laundromat and one assumes domestic front loaders today have triple or double locking systems so the door cannot be opened until the drum stops.

Door Lock

@Launderess

Thanks for the input! I really liked your link about the history of different front loaders. To answer your question about the door lock, yes it does have the updated door lock system. As soon as the machine starts, the electricity to the door is turned off. It also has an electronic system with a magnetic sensor that senses when the drum is turning. It also disables the electric door lock when the cylinder is moving.

When I was growing up a couple of laundromats that Mom went to before she got her WP automatic had Big Boy machines, I would get a chair and sit in front of them and watch as though they were TV's, LOL.

I as well as a child would watch that machine and loved the sounds it made. The Loud Clank of the solenoid when it drained and the motor winding up for the 2 speed extract cycles. I would love to see a video of the Full Cycle when your finished. Thanks, Eddie

Big Boy Sounds

That’s funny. I too remember when I was young watching that Big Boy, and our town Pharmacist referring to it as watching TV. Too bad it won't have the drain clunk anymore. We updated the drain with an electric gate valve from a Speed Queen Super 20. Sure thing after it's going I will be sure to upload a video. Thanks guys!

The pics of the rebuild are great. Looks like she'll be back to super loads in no time. I'm trying to understand the 2 motor system...so the wash motor actually turns the shaft of the spin motor which turns the drum at wash RPM's through the pulleys on the spin motor shaft? The spin motor obviously has no power to it so it just free-wheels? Then for spin, the spin motor tuns the drum directly for spin RPM's and the wash motor free-wheels? It seems so simple; no gears, speed changers, shifters or clutches or modern VFD's. It really can't be more expensive then all that other stuff used to change speeds. I believe the Easy combo actually used two motors. I'm surprised more manufacturers didn't do that. What is the spin RPM anyway? Thanks for the info.

Two motors

Your exactly right about how the motor system works. The spin motor is nothing more than an idler during the wash cycle, and the wash motor is just an idler during spin cycle. The greates amount of noise the machine makes during the spin cycle is the wash motor just going along for the ride. The fan inside the motor is just screaming. As for the spin rpm, i'm not sure. The wash motor is 860 rpm, and the extract motor is 1750 i believe. Next time i'm over there again i'll have to measure the pullys and figure out the spin rpm. Thanks for your interest!

Very cool!
Nice to see you rebuilding it!
The motors are enormous! I bet is is such an awesome sound when going into spin!
Do a video if you can!
Thanks for the pictures!
Great save!

WASH MOTOR SCREAMING ALONG

combo52's profile picture

Isn't there a one way clutch in the pulley on the spin motor that allows the wash motor to not turn when the spin motor takes over? Many other large FL washers used a two motor drive, including the Easy combos and they all had a helix coil type clutch to keep the wash motor from dragging along while it tries to spin. I would guess looking at the picture of the pulleys that this machine spins somewhere around 350 RPMs. Thanks for sharing the rebuilding process, I look forward to a sight and sound video.

Spin RPM

Just went over and measured the pulleys, also checked the spin rpm with a manual tachometer. The Spin rpm is about 380. This machine would be so much quieter if there was a clutch to disconnect the wash motor during extract, but there is not, it’s all rigid pulleys. I never checked the rpm of the wash motor during the spin cycle, but I would guess it is around 6500rpm. Latest project I’ve got with the machine is replacing the bearings in the wash motor. There has been a lot of spin cycles since 1966, and the bearings show it. Luckily they were easy to find down at the local auto parts store. Thanks for the interest! I will post a video soon.

Laundroguy77,  interesting you mentioned the drain valve from a speed queen super 20, i remember them and i think that was the first time i was shocked at a scanty amount of water.  The Super 20's were kind of an odd duck any way with that perforated bottom panel, i guess a good idea for air circulation.  I see the "Big Boy" logo on your control panel, as a young lad, I remember the "Big Boy" logo on the glass as well as a cartoon character, kind of a morph between Shoneys "Big Boy" and the "Pillsbury dough boy".  Nice work on your restoration and thanks for sharing your photo's, alr

Thanks for all the information. If your machine is a 1966 and has only been out of service for the last few years, that's a damn good track record! How has it been in those 40+ years repair wise? It seems to be very well built but simply constructed. Are those the original motors? I guess "freewheelin" hasn't had such a bad effect on it if you are just changing bearings now. Can't wait to see and "hear" a video if you get the chance.
This thread hsd sparked my interest in these larger capacity laundromat machines. Seems all the newer ones use one motor with inverter control for drum speed and distribution. What other machines do you know of use the 2 motor system?
Again thanks for all the pics and inf, great job..
Kevin

Wash Motor

The wash motor turned into a little more of a project that i thought at first. Now I need to get a couple parts for the start winding contactor. Found a website that sells them. Hopefully i'll get them ordered this week and get it back together. Heres a picture of the gutted motor.

Big Boy/Two Motors

@alr2903
Yes it does have the cartoon character you're talking about on the control panel. I'll take a closer picture of it and post it on here. It is a little faded. It is a blue/green guy wearing a suit and a cap. As for the super 20's, I don't know much about them. We got the valve used on eBay.

@spin-it
It has over the years been a pretty good machine. People like it because it's so big. It has needed some repairs over the years though. My dad has had the Laundromat since 1988. It was out of order then, if I remember right it was a simple fix. A hose going to one of the pressure switches was plugged with lint. In 1995 we put bearing and seals in it, just like we did now. Also replaced the door lock and drain solenoid a couple times. Honestly, now that we have done all the work on the drain and the door seals, this is probably the first time it has ever had no leaks. Seems like it always had a drip or two. As for other machines with two motors, I'm not sure. I believe some of the Milnor's have two motors, but I have never worked on one. We have 3 speed queen sc27's, a Wascomat w-74, and Maytag Neptune's, and they all have one motor. The Neptune's go through bearings and seals quite often. We have 6 of them, have changed bearings and seals in almost all of them once, and there only 6 years old.

Thanks for you're interest guys!

Big Boy Cartoon character

Here's the picture of the big boy cartoon. Be nice if i could find a new decal. It's pretty faded. I originally thought it was blue, it's actually red.

Glad you got it running again! Watching this brings back a lot of happy memories, of my mom and I at the laundromat.

Not only for the memories, but a Front Loader that actually uses enough water to see it in the window. Thanks for all your Hard Work keeping the "Big Boy" alive and well.

Oh, I used to be fascinated with those! The Poly-clean laundromat used to have 3 of them side by side. How I loved those trips to the 'mat--Mama took big things that she wouldn't put in her machine at home. No air-conditioning, just a BIG fan in the wall--which, naturally, also fascinated me.

We had one of these in the first hotel I worked in. The only difference in the panels was that there was a cycle dial which we turned to the beginning of the cycle, loaded it with what we were washing (usually towels and pillowcases) closed the door and hit the start button. It did have automatic dispensers for the chemicals for the laundry. The other one was a giant Laundrite, it was turquoise in color and I remember that when it spun, it sounded like a jet plane taking off or coming in for a landing when it stopped, they were workhorses. The last time I went there, the big turquoise laundrite had been replaced with a Milnor but the Big Boy was still there and still churning away.
