Guys change the lube in your Transmissions , then there will be no chance of it freezing with water in it!!!!!!

Not a bad Idea to use Hy Tran :D

I did not know that water in the trany was such a big issue. But when i got my last cub I had replaced the missing gasket on the shifter and had dumped some gear oil in there just to lube up what i could get to. I cleaned out the pasages were those little lube holes are in the casting. Then I figured I would drain and replace all the oil in the trany. Boy was I surprised to see most of what came out was water. Dont know how long it was like that . I know it sat there in Maine for two years with out moveing. How come the winter freeze did not split the casting? I cleaned the trany out with deisel fule and refilled with gear oil. Doing a complete dissasembly is on the list for down the road. What would be the best way to prevent water intrusion on a out side cub? I dont want to tarp it but I guess if thats what it takes thats what ill have to do. My loboy is out side all the time an has never had this problem. How does the water get in there in the first place?

Part condensation and part rain that runs down the shifter. Even keeping it inside won't ensure the water will stay out but does lessen the effect. I guess you could flip a 5 gallon bucket over the shifter to keep most of the rain out, but the condensation will still get in.

Only takes 1/4 cup of water to lock up the gears. Would take much more, to split the case. Ed

They don't always have to be outside. Just after Christmas it turned cold here and then about 10 days ago it warmed up real quickly to about 65 degrees. There were water puddles underneath all my tractors on the concrete floor from the condensation from the cast iron. Even the sheet metal was damp.

Yeah but the effect of condensation is limited. There's only a small amount of air space in the transmission cavity and very little air exchange.

Most of the water that gets into the transmission is from rain.

I should put a small bucket over the ones I keep outside, but only did that on one and now it's under cover. It is very often a problem and water will eventually ruin the bearings. HyTran will take up some water, possibly even all the condensation of one stored inside. Matt Kirsh is right about it being 'sealed' and condensation should be minimal on the inside of the case.

IH eventually put an O-ring on the shifter, but not sure how well that works. If I have the shifter off I put one in when there isn't one there. 1/2" x 5/8" x 1/16"

The 8/64 and 3/76 operator's manuals say to change it ONCE A YEAR, PREFERABLY BEFORE FREEZING WEATHER SETS IN and do not drive the tractor 1000 hours without changing it. Both manuals list HyTran as the stuff to use, but the older one allows gear oil (after HyTran).

May be a good idea to put a magnet in the drain plug.

BW, I am not sure that many pay any attention to the manuals.

If you guys remember the old small gas engines that you started with a rope, gramps always kept one of those ropes with the old wooden handle tied around the gearshift. I'm thinking it was there to act as a "drip loop" to keep water from running down the shifter and into the trans.

I pulled the drain plug from my LoBoy last week. I did this after the shifter seemed really stiff, probably had water in it.
I had never drained this cub before and it has super think reddish stuff in it. It also has way to much. I had posted this already. So I picked up some HyTran and brake cleaner today to clean her out and fill her up to the proper level. I moved the drain pan containing the old stuff and wow, it did not move a bit. I have heard of molasses in January but I put the pan up on one edge and waited for it to move. It finally do but so slowly.
Wow no wonder shifting was tough.

Might want to consider HyTran Doug!

I think all the lubricant exited my 50 years before I got it.... kinda wonder how they wore out the cutting edge on the snow plow in northern Vermont with a tranny full of water :shock:

Cuts down on gear grinding, Doug. :shock: :lol:

I think this will work until the mice find it and use it for a home. Old piece of inner tube from a front tire cut about six inches longer than the shifter.

Won't win too many points in the beauty contest, but I'll bet it is effective.
