Hydro leak

[RAllison]

Uh-oh, my turn to learn about my hydro unit. Time to get out the power washer and head to the FAQ section and chase this thing down!

Just HOPE that some one DID NOT use bolts for that homemade hitch plate that are TOO LONG!!

If they did, you are probably threaded, as the bosses in the casting will have been broken out or at the very least cracked

 

[RAllison]

Whaaaaat? That things been on there since I bought it around 10+ years or better,never leaked a drop. Something to look at though,thanks Dave.

I did kneel down last night and have a quick look when I saw the puddle, seemed to be coming dropping from the front of it a little higher up.

 

[RAllison]

Sitting here thinking about it...I had that cover plate off last year and don't remember any bolts being longer than the others.

if I had to guess I'd say its the dreaded cork gasket that seals the hydro unit to the axle. Common leak point, gonna have to replace it on my 107 soon.

CCS carry them?

OK, then, wash and dry the area thoroughly.
Douse the area w/baby powder and the leaking fluid will leave a trail in the powder and lead you right to the leak.

I surely did not wish a heart attack on you Bob!
Thought this Cub may have been a new acquisition is all.
Just the first thought to cross my mind as well
I agree, the cork gasket would be the 1st place to suspect.

Question for experts, I have to replace gasket on my 129 , need to verify bolts to remove and shoulld I use any sealer ?

Cleanliness is utmost importance. No dirt to enter transaxle. I use a bit of Hi-tack to retain cork gasket to diff, then carefully set the Sunstrand hydro on the diff unit and then tighten bolts. Some visual aid:

Looks like I'm gonna be busy!

The new gaskets have one side sticky, just remove the wrapper that is stuck to it

Apparently, I bought an older or aftermarket cork gasket. It did not have any adhesive on it.

We used to use Vaseline to hold transmission pan gaskets in place. Just a few dabs around the gasket.
