Hi all.  Getting my "new to me" SS12 ready to mow.  I changed the engine oil, and the trans oil.  The tranny oil was super milky.  Where is it possible for water to get into the trans?  I'm sure it must have a vent, but wow, the oil was like condensed milk.

 

Any thoughts?

Thanks.

H

You were right to drain that out. It may have leaked around the shifter. I use an old trick. When a tractor has been sitting for a while, I loosen the transmission drain plug to let any water out. The thicker oil doesn't leak by the threads. Good Luck, Rick

If you can get hands on an old inner tube, try this.

Cut a 7-8" circle, find center and use a hole punch to make a 1/4" hole.
Take off knob, Slide rubber over the shaft and by pleating it, you can get it under the body where you don't see it.
Position it so the pucker is up, not down like a funnel and you just drastically reduced the water that can get in.

My 16/6 was very milky when I drained it, just seeped in. I think they also get hot during use and on a humid day as they cool down, they suck moisture in. Do it enough times and you develop some water in there. Gettni gready to pull and drain my ST16 rear, hopefully it's fairly clean.

Condensation produces a lot of water.

Installed the rubber disk as per MH81.  

Got to thinking about what TAHOE said.  I'm into old brit bikes.  I install a "one way" valve on the engine breather.  Not for the same reason, but it would be appropriate.  

 

Where is the trans breather on my SS12?

Don't think they have one. Unlike most cars/trucks, they do not generate enough heat/expansion to need a breather like on a car rearend. I think the suburban rears are basically sealed once you put fill plug back in.

:ditto:

Tahoe is right, they really don't have one in the normal sense... the shifter, etc all leak a little air and would more than handle any expansion/contraction it may need.

I can see what you mean about a breather, makes sense.  The rubber ducky shifter disk is installed.  It will knock one possible water source out of the loop.

 

Thanks again

It would be hard to take a picture.  If you refer to post #3 in this tread there is a good description.
