It seems my tractor (a 3 year old B7610) is showing signs that of developing a leak on the left front axle at axle flange interface. I did a search and see that this is the typical location for a leak on the front axle of these tractors.

The "leak" is more of an oily film developing on the flange surface itself. Has anyone tried simply moving to a heavier lubricant in the axle rather than the Super UDT. And if they have, did it solve the "leak" problem"?

Thanks,
Dave

My 4 year old B7610 has the same leak. I figure that I will eventually be pulling it apart and replacing the seals, etc. I am guessing that I should expect it with the large amount of heavy load work that I do with it.

My BX2200 just started too, changed to 80-90W as per the manual, still leaks.:mad:

I have not had a leak yet. I did change the front axle fluid at 100 hrs from UDT to 80/90 gear oil. My dealer said that going to gear oil is the fix. Wait till you see the crap that comes out of that axle when you drain the fluid.

Quick question -
Is the plug with the dipstick screw in or just push in/pull out?
Trying to "unscrew" mine a bit gets nowhere, but can't easily get my hand on it to pull out.

It is just push-in/pull-out. Turn it and pull and it will pop out.

Not sure if the B7610 has the same hub configuration as the BX22, but I have a leaker too.. Took to the dealer and they replace the seals three times (on the same work order), and the last time they used silicone around the seal to see if it would help. Nope, it still leaks like a siv :mad:. Puddle on the floor siv..

Can you take a picture of the hub and the place it is leaking from? How about you NY Yankee Fan? Maybe we can figure out if it the same place that is leaking.

My theory, on the bx22 anyway, is it was over loaded at some point and was too much for the hub. Guessing it bent one of the parts just enough to keep the seal from seating well.. Just don't have $300 for the parts to test the theory right now.

Not on mine!
It's grab on with a wrench and haul like HECK to pull out and PUSH like the devil to put back in!

Plus it's got the FAMOUS INVISIBLE Super UDT (undetectable transmission) FLUID!!

Does the 80-90W at LEAST have some detectable color in it?

My dipstick fill plug was very difficult to remove also. I had to pry it up with a small pry tool while rotating it. It has a double o-ring seal to keep debris out.

I used gear oil from a company called Lubrication Engineers. It is red in color so it is easy to see. All you need is a good quality gear lube. Most of them are darker in color then the udt so it will be easier to see it.

Thanks for all the replies to my original question. I think I got my answer... changing to a heavier weight oil isn't a "fix".

The leak on my B7610 isn't bad, at least not yet. Its more of a wet look around the axle flange interface. It definitely isn't dripping or making a puddle on the floor. At least not yet.

So, I guess I'll continue to use it until it gets worse and then replace the seal. I understand its not that difficult of a repair.

Thanks,
Dave

I checked the oil level in the front axle yesterday and observed (and felt) what I consider excessive positive pressure when I removed the dipstick. I have checked the oil level in the front axle before, but never noticed (or recall) this much positive pressure built up inside the axle housing.

I couldn't help but wonder if this excessive pressure contributed to the "wetting" I have observed on the left front axle flange.

And lastly, has anyone else noticed this on their B7610? I would have thought there would be a vent to prevent this kind of pressure build-up.

I have the 7510 and changed the front end to 80w-90 with recommendations from my dealer. The plug was hard to get out and I had to twist and pull as well, it certainly is not easy to get a grip on. I don't have any weeping yet but I will be keeping an eye on it now that I know. The heavy oil is much darker then the sudt easier to see on the dipstick. I wonder if you could add some food coloring to the sudt to make it stand out? Anyone try this?

I had a ford , that would buildup alot of pressure specially when running on the road I would have 'wetting' and then leaking on the front seals.
I replaced the plug with a 1/2 in pvc water plug and drilled a couple of holes to vent in it.I dont understand why they are vented in any way formt he git go.

I had the same problem with my 04 B7610.Dealer fixed one side,i brought it home ,two wks. later the other side started leaking.Ended up trading it in for a B26,not because i did'nt like the 7610,but just wanted something heavier.
The B26 has'nt leaked yet.....i'm keeping my fingers crossed.
When i had the 7610,i remember doing a search on TBN and found a piece about "venting" the front axle.Try doing a search under "venting front axle".There was a step by step thing with pictures and all.Worth a try.

I thought of that also, but isn't food coloring water based?


There are commericially made additives to color oils for visibility and identification .....This came up in a thread on checking hudraulic oil on the silly yellow dipstick..Hard to see....

But of course I didn't write down the information then.... :rolleyes:
