Venting the front axle on CUTs(with pics)

[Rob-D]

I am a little confused..... in 100 hours you are saying you pushed ALL if the gear oil out of the seals?

You did not see any of that gear oil?

That seems to be a lot of gear oil not to see some trace and to be able to push it out in 100 hours

What I think he saw was that the dipstick was dry. I'm sure there was oil in the case but it wasn't full. I just talked to him and never inspected it.

What I think happens is the oil gradually gets pushed out the box over time and you don't see one big purge. I didn't examine the axles and seals closely but I think if you pulled the wheel and started to examine things you'd find the source. After all, if the level is dropping it has to be going somewhere.

How often did original owner check, if ever, and how much of a drama queen is the new owner over a 1/4" low reading? A little oil makes a BIG mess. I have a tractor trailer that leaks at the front end and some days leaves 6" puddles in a yard at a 15 minute stop. Parts of it from the cab back always have a thin film of oil on it, and I do upwards of 400 miles a day, yet I add well under a gallon a month.

Bottom line, as Lilranch is getting at, I'd think if you lost a quart or so of oil, there'd be a ,very unable to miss, mess. I'd have to wonder if you never really checked it, and neither did whoever set the unit up at the dealer.

Therefore whenever it comes to my equipment, I trust no one until I see it with my own eyes.

I did check it when I got the tractor but figured it would be fine with only 100 hours on it. I traded it and the guy was annoyed because the dealer didn't address it. I was out of the picture by then.

I would have to wonder if he check'd it correctly. Doesn't seem like it'd take much of a slope to get the oil away from the stick, at least on the two NH's I've had.

Did he buy it direct from you, or a trade in? Curious just because he involved, and was upset at, the dealer over a relatively trivial "problem".

... but the early print manual calls for 4L of it while the latest and greatest calls for 7L...

I believe this is the one that was recalled because the front wheels were ripping up turf in turns. And its supposed to be quite different from the second generation axle. My tractor is a 1999 and should have come with the original axle but I have the update so the recall was installed at some point.

Yeah, the smaller capacity and the smaller bolt count would indicate the
earliest axle (107) was much smaller. Maybe that one is the one that
had the most problems?

I agree with SPUDLAND above....4 different axles in less than two years
span....something was amiss. Some of the differences were significiant;
others seemed minor.

Good point Haymaker,
I traded it in to my dealer who's a really good guy and a pleasure to do business with. The guy who bought it was a city guy who only comes to the country once and awhile. He may be a good guy but I don't know him.
To do my dealer a favor I told him if he had a buyer he could take the 2720 before my new one came in. The guy came up and drove it around my driveway but he really didn't know anything about tractors.

I'm lost on the front axle fluid I also have had the leaking problem. I like your fix idea. But in this thread you speak of 85 weight gear oil , my local JD dealer cautioned that I only use JD Low viscosity Hy Guard. Not the regular Hyguard. Comments?

:welcome: to TBN

Follow the manual for the right lube in the front axle. Don't think it is gear oil.

Wow....glad I ran across this thread.
I haven't read threw all of it yet...but heat has to be the reasoning.
My jd 2320 front axle first leaked out while sitting.
I am a charter boat fisheraman...so in summer (Florida) I work 14-18hr days 7 days a week...my tractor sits for 2-3 months.
It did it again this year. Notice the seal leaking. This is after heat index gets over 100-115 degrees down here.
I'll be back reading more on this....gotta go.....thanks!!!

Ok...I am thinking out load and do not the the proper terminology. ...so please forgive my ignorance here.

When my seal first started to leak......I ask hear. Of course I was told the possibility of dirt getting into seal...etc..
Sounds legit...since I was doing alot of digging at the time.
So I took wheel off and the outter case part area the wheel attached to. If I remember correctly that area is fill with oil/lube from a small hole that comes from the axle cavity area.
Ok....so my question is.....is that hole big enough to allow the oil to be pushed back up.....back threw to the axle?
Of course speaking as if the heat.....oil expands that quick?
If the oil expands quicker than it can flow thre that small hole......seems like this could also be an issue?

Or did the vent eliminate seal leak issues?

I could be completely off here and speaking in amateur terminology. ....but had to ask/comment??
