Stuck Main Drive Pulley On A MT Washer

Hi Harry, what on earth happened to this washer that allowed the main drive pulley to get so corroded etc.

 

It looks like the machine sat in 4-6" of water for an extended time for this type of damage to happen.

 

The shaft and pulley are greased when assembled and I have never seen one that was even slightly dry let alone rusted together, what is the condition of the rest of this washer?

I know John!!! Absolutely baffled...the only thing I can think of is water had to splash and spill over into the drive shaft as it spin. After the rebuild, all parts needed to be greased were...I'm thinking spin or splash spillage...The rest of the machine is fine...I just don't know...this is my best "guestimation" I think she's a gonna!!!
 
Okay, finally was able to remove the transmission pulley rusted to the helical shaft. Sprayed rust penetration down the 'water deflector' to reach into the corrosion. Not quite sure what happened, there are rust spots all over the lower end of the transmission, the radial bearing is thoroughly rusted. Check out the brake and the helical. Not sure about the tub bearing seal. Experts, any ideas on how water was able to seep down and cause this?

Rusted Brake Release Bearing

This type of damage is a little unusual but something must be leaking from above,

 

The rusted bearing is not the radial bearing, this is a sealed ball bearing right above and set into the brake package, this bearing may also be damaged. 

 

Try lubricating the release bearing and put every thing back together if the release bearing turns and is not too rough. If the washer works but roars at full spin speed you will likely need to replace the radial bearing and you may need to replace both.

 

You should watch carefully for leaks when you use this machine for a while.

The transmission spline and helical shaft are rusted...what is the best thing to use for the rusting? Is it necessary to replace the brake package?

For some reason Dan, your words "past life" caused me to remember what happened. A few times I forgot and left the bleach dispenser hose unattached...(don't remember exactly what I was doing) but, while the machine was filing water overflowed from the hose and spilled onto the baseframe...' underthought' about the amount of water leakage possibly down into the shaft...not realizing the damage I've caused. Can I save the spline and helical shaft?
 
The threads on the helical shaft and splines for the brake package are coarse so you should be able to successfully use a rust remover/dissolver.

 

Finding a new 200835 pulley bearing will be a challenge. You'll probably have to source a used one from a donor machine.

 

If your 712 was built after June 1986, replace the lower lip seal.
 
I would replace both those bearings while they're out for peace of mind. Just add a teaspoon of oil to the brake package ( SAE90?) the splines and rust can be cleaned with a coarse then fine wire brush. Wire wheel on a drill is even better.
 
Thanks alot guys...Hey Lorainfurniture, I'm sure your shop is close by now but, I'll take the deal!!! How can I order them both, (brake and top bearing) online?

Dan, I'm not sure what designates the year built but, all I'm able to see clearly is my model number and series '04' number.

I feel the same way you do robbinandmyers, that's why I asked about replacing the brake package...'peace of mind'

Hey guys, I may be able to have her up and running tonight or at least by the morning. When I laid the washer on its back, I noticed water leaking down inside the back of the cabinet from the siphon break and drain hose area but, when I felt for water, it was dry. I removed the outer drain hose to see if the siphon break 'elbow' was cracked, it's fine. I laid it on its back again...water drained out the elbow, as should but, no leaking inside the cabinet. Input will help me move forward.
