Finally found my leak!!!
 

Bought a 3206 last fall, (No SN to be found) had a leaking hyrdostatic, old owner "topped it off every so often" I climbed under it and cleaned off the amazing amount of grass blocking everything including the fan :angry:
I could not locate the leak. Well now that snowblowing season is over I tore it down:https://photos.app.goo.gl/coQ9dRWwrajPNY828

I had just about given up when I saw a little seapage:

(Notice it between the black and silver parts in the crack)

So my question is do you guys think its the o-ring in behind there? Do I need to pull the other lines off to get it out to change the o-ring? Will I need to buy other orings if I need to pull those lines out?

I think I need two of these at least:

22
O-Ring
Part# HG-9004100-1430
Your price: $2.88

Can anyone tell me what else I will need or any special parts?

You didnt give us much detail to go on here.. Some pictures might help. We can not see what you saw..:HeadScratch::Huh:

Sorry! i'm trying I tried to share form google photos but that doesn't create a link to the image, i'm putting them on a new webhost now just a second.

Added Photos! It fought me but I linked them in

If you are sure that is where your leak is you'll need qty 2 of part #22. You will have to remove the lines on the charge pump to remove it and I would advise replace the backing rings and o rings on the lines. Sprinkling baby powder on the transmission could be helpful in isolating the leak.

Right so I plan on getting:

From this: https://www.partstree.com/models/320...ansmission-19/

two 22 HG-9004100-1430 0-Ring
one 37 HG-2000044 shim

two #29 721-0459 o-rings for the Hydro pickup (had to remove)

two #12 o-rings 721-0492 Hydro tubes I had to remove

I think that should do it. its definitely the only source of oil I see.

Anything else I should replace while I have that open?

This was broken when I pulled it out, not sure if it retains fluid?

Also these are some of the other o-rings I mentioned

When it comes to stuff like that.. Cheap enough to replace, I just replace it.. Do it once and be done with it

coop is right, ya you can sometimes in a pinch, reuse "O" rings and works just fine, other times it bites you in the ass.
so easier to do the job once and done.
Especially if there are many things to remove to get to the source of a leak.
time is money.

I totally feel the same way, thats why I was asking if there was anything else I'm missing!
