Water in 418-a Eaton Model 11

[Old Ron 1]

I have a Eaton Model 11 with water in the transmission. 

I have been filling with oil and installing a new filter, then running for a few minuets and draining.

I have done this 3 times and oil still comes out cloudy.

Anyone have any other suggestions?

Jack up the front of the tractor so the front wheels are a foot or two off the ground while draining the oil out. There’s an internal hump in the transmission. Jacking it up will help get the oil over that hump. Also cycle the hydraulic cylinder a few times to help purge the hydraulic valve, lines, and cylinder of water. Do you have any pictures of your tractor? Those 400 series are some of my favorite WH’s ! I have a 416-H, 417-A, 418-C, 418-8, and a 420-LSE.

Welcome Ron.

It is real hard to get all of the old oil out of the Eaton 11 system. 

Is the oil just cloudy or is the pronounced water that comes out of the drain plug?

Motor oils can take up to 1% water and retain their lubrication ability.

I would not panic.

 

Like HD says, the bulk of the oil is in the sump and filter and you have drained those. Some residual is in the charge circuit. 

One question is how long have you left the sump drain? If you raise the front of the machine up and leave it over night that will help the drain.

If the oil is just cloudy it would be best to run it a few hour and preform a drain and refill.

@c-series don, the missing gem to your 418 trifecta!

Thanks for the info!!! The oil just looks cloudy. I will jack up the front end ..

Not much I can add to what Joe and Don have said. Since oil floats on water it may be advisable to allow time for the two to separate prior to the next draining. 

This service manual for the Eaton1100 may be helpful.

to the  Ron.       How did water get in an Eaton hydro?

I am not sure about Ron but I left one out for 2 winters.  I was out of room and figured those transmissions are sealed up pretty good.

The snow and rain pooled around the fill tube and migrated into the case. I figure the heat cool cycles helped too. That was the only way I figured it got into the case. 

 

At work we had found pallets of oil that was contaminated with water. Found out the supply yard thought they could leave the 5 gallon cans out in the weather. Heating and cooling, the rain that was on top of the cans got sucked inside. Industrial CSI

Another source is the vent in the fill tube handle allowing in/out movement of air (which always has moisture in it). Warm/cold cycle causes condensation.
