We-6 agitator motor

Hi.  I have a we-6 wet cooler that has a broken cast iron agitator motor.  Can these be fixed or is there a good replacement available for it?  

Thank you, Doug

[johnieG]

Yes! it's avalible as a repro-Item or check out Graingers part No. 5M067 ,  Cast Iron "Unit Bearing Water Agitator", rated@15watts 115 VAC, 1500 RPM,CCW rotation (as viewed from the shaft end.) shaft spec's are: 5/16" x 7" with a 1/4-20 thread on the end, about $78.00 or part No. 5M068 same spec's but  5/16" x 5" long,with a 1" long flat machined onto the end of the shaft, (for a coupler) about $74.00  :'>  
Hope this helps!

Thanks for the response Johnie.   Will it be a problem that this motor spins faster?  I think the other one was less than 1000 RPM's.  Also, do you know if the grainger one is a direct bolt in or does it take an adaptor?

thanks again, Doug

[johnieG]

Naw 500 RPM's extra will only circulate the water around the tank a little faster is all, yep it bolts right up using the same three mounting holes to the bracket, if yours has only two screws mounting it to the bracket you can still use it with an adapter plate either part No. 1C897/~$6.00 or No.4M738/~$3.00  goto www.grainger.com and checkout their
online catalog for pictures, etc.

That's great news.  Mine has the 3 mounting holes so it should work perfect.  Lokks like I need to place an order.

thanks again Johnie!

No problem, glad to help, Dlyle, just make sure it's the right length, yours may have an old rubber shaft coupler between the motors shaft and the circulator paddle, measure the length from the face of the motor to the end of the shaft to confirm, also double check which end you need, a flat, or a 1/4-20 thread-end, you know where to go if you need any more info! let us see some before and after pic's of the motor assy if you can! (and the cooler too!)

Here's apic of the Graingers motor ( with the threaded end) look familar? '>

Excellent resource Johnie!
You continue to amaze me!!! '>

Johnie,
On topics like this, you could Pin them as I have done for this one so they stay at the top of the list...

Hi Guys.  I'm a little confused now.  It says the motor runs CCW but when I look at it it apears to run clockwise.  I'm looking at the impeller right now, looking from the bottom of it (the end opposite where it attaches to the motor rubber coupling) and it spins clockwise.  The impeller blade is correct, I have another working machine to compare it to.  It spits water out the top and everything.  I've talked to Steve at funtronics and his catalog also says CCW.  Are we sure it doesn't mean CCW as viewed from the top of the machine?  
Thanks again, Doug

I looked at one of my other motors for reference.   The fan motor for the condensor says it's a CW motor...and it does turn clockwise, but only as viewed from the motor side, not the shaft side.

Thanks, Doug

[johnieG]

the rotational direction of the motor is viewed at(or SHOULD be) the front for the motor looking at the shaft, so for a CCW motor if you are above it looking down on a WE6,it will appear to rotate CW (clock-wise) see attached diagram... but again, if the motors manufacture list's it differently it can be confusing      look on the back plate of the motor there may be a directional arrow too, then they mean the rotation is viewed from that end (per the arrow)

Thanks for the diagram Johnie.  From what I can tell the motor direction you show would be backwards for my machine.  It would push the water down.   The arrow should go the other way.  I have 3 of these machines and they all have the impellers going the same way, so I don't think mine is mounted upside down.  I found a website that says the following....
Determining the correct rotation of the motor is essential to the proper operation of the system. It is quite easy to get the rotation wrong. The rotation of a motor is normally stamped on the motor’s data plate. It will be stated as being either clockwise (CW) or counter-clockwise (CCW). How-ever, this rotation is based on how the motor is viewed — from the shaft end or lead end. To make it simpler, some manufacturers include the orientation with the stated rotation. For example, a motor stamped “CWLE” means its rotation is clockwise looking at the motor from the lead end of the motor; “CWSE” means clockwise rotation looking from the shaft end.

I guess my problem is that I can't seem to find which way the Grainger motors are viewed from.

I don't mean to be a pain.  I'm sure I'm suffering from some acute mental block because I know this should be easy.  I'm just trying to get the right motor.  One other thing I did was hook the impeller and shaft in to my drill.  I then put it in the cooler water.  Going counter clockwise as viewed from the shaft end it pushed the water down.  When I reversed the drill rotation to clockwise it pulled the water up like it should do.

Thanks again, Doug

[johnieG]

would it be easier (if possible) to just mount the impeller backwards to keep the water flowing in the right direction?

The way the blades are positioned it wouldn't be effiicient.  the blades are completely flat on one side, the other side curves up sharply to produce the desired water push.  if I turned it upside down the flat part of the blade would face the top.   I'll try and take a picture tonight and post it so you can see what I'm talking about.     I must say in the 3 days I've been registered on this site you've been a huge help.  Ii spent countless hours cruising the web and looking through catalogs (even the Grainger catalog) trying to find an agitator motor.  Never did find one.  You provided me a part number right away and I really appreciate it.  The numbers you gave me even said that they were agitator motors! And your drawings and pictures really help too.  Anyway, thankls again Johnie.  I owe ya.

Doug

Here's a picture of the impeller.  I probably could bend the blades and have it spin CCW...but I'm determined to find the right solution.  I found a guy that's going to try and rebuild the original one.  I had to send out over 30 inquiries before someone responded.  The guy that agreed to finally look at it originally said no, but I begged him nad he decided to take a look.

I just purchased a WE-6 also and its my first restoration machine so Im being very cautious. In this post I have a few questions concernign my machine. For starters the macine seems to be 99.5% complete but I noticed the elecetrical wires are suffering from severe dry rot so therefore I dont know if my machine even works because at this point I feel with the wiring it is a total fire hazard. I have purchased a plug to replace the original (which was cut off, for who knows what reason!)

1.- Now here the tricky part... this pump that all of you folks are talking about has wiring with dry rot so therefore I want to replace it but I don't know how to access the inside of this motor to replace the wiring. I cant see or figure out how it opens, can someone help me.

2.-Also after I replace all of this wiring is there any thing special I need to do before plugging the compressor in and testing to see if the compressor and condensor work.

3.-My pump and blade appear as if they were held together with a rubber shaft coupler but it has dry rot as well therefore it doesn't hold the motor and fan shaft together. What should I do.

4.-If I order one of these reproduction manuals that I see for sell for my machine does it list part numbers and picture so that if I need replacement parts I can just contact somebody and give them a part number out of a book.

5.-Where is the best place to get Westinghouse replacement parts.

Hi Guys,

  Just thought I'd add a little something about the motors. It looks similar to the watt fan motors for the coil, condenser and evaporator. These motors, up 35 watts, are what we call a "51 frame" motor. If you want to know which rotation you have, you read cw or ccw from the motor end not the shaft end. Hope this helps.

I'm interested in the response to hndapwr's question about re-wiring the agitator motor.  I'm in the exact same boat.  Are these sealed units and un-rewirable ?  Now there's a technical term '> .

Thanks,
Bob

Brent,

You're right!
I never followed up and researched this phenomonom (spelling...?)...

[Jim]

Hello again,

I just checked and wasn't able to post without being logged in for almost all the Discussion Areas; I didn't manually check everyone...

The only thing I can say is that due to the dates, I may have had a setting improperly set and found it later only to correct this for later posts...

Yea, that's it, that's what the problem was...  

[dr galaga]

Oooops! I didn't notice that it was from 2 1/2 years ago (no wonder it seemed like a new topic to me!).

Does Grainger (or anyone) carry the blade to go on the agitator motor JohnieG referenced earlier in this post?  Grainger has some fan blades that look as if they would fit, but they would push the water down instead of up.  I can't tell if you could mount them upside down or not.  Anyone have experience with this?

[Jim M]

Hello all, any updates on this as I have a WE6 with the same issue....

can the machine be run without the agitator running?

thanks, jim

[90grad]

You need the agitator motor to run to circulate the water.  Otherwise, you won't get proper cooling.  One of the sponsors to this site, Funtronics, carries both the motor and blade.

[Jim M]

already ordered a catalog from him last week, nice to know parts are still out there!

thanks, Jim

[Jim M]

I was wondering... although not 100% correct, would a sumbersible pond or waterfall style pump work in the meantime? A pump of this sort is about $30, vs $200 plus for a retrofit circulater motor...

fun-tronics says they no longer carry that motor???

ideas and thoughts?

I have searched and search on the funtronics site, and I am just not finding the agitator blade anywhere.  Anyone know if they still carry this?

Here is a full motor and blade on eBay: http://www.ebay.com/itm/Soda-Machine-Agitator-Motor-For-Cold-Water-Bath-115V-/170791272428?pt=LH_DefaultDomain_0&hash=item27c3f3ffec

They aren't easy to come by, are you just looking for the blade?  Maybe hit up a hobby shop and see if they sell a propeller for a model boat that you could modify?

[sbcroix]

Awesome post!  I doubt I will be buying that, but just the picture is good enough that I might be able to make one!

Thanks!

[johnieG]

Graingers.com  may have a lead on just the "propeller"  portion (agitator blade)

[scalebowler]

that propeller in the ebay link looks a lot like those plastic fan blades that they put on those little shaded pole motors
