Warranty on work

[Bje56]

Here is one of the work orders for everything but the front axel. Not sure if there is an insinuation or not of me not being truthful. Hope not. I apologized for the long text because it was long and that was sincere. As was my appreciation for those who offered perspective/advice and those who pointed out the truth about the length. I’ve never posted anything before. Anyway here is invoice. Will get pics of seals tomorrow or later tonight. Thanks again.

Also there is no vent and I did here some pressure being relieved when I unscrewed the fill cap for the front axle. I did have it in and out of 4x4 and worked the tractor yesterday. I checked it this morning .

Oh my goodness no! Certainly not by me. What I tried to express was that this is an odd situation with some aspects of it that don't make sense ( like why the previous owners would have the axle seals replaced at 89 hours and what the loose steering wheel is all about.) My first guess being that you were being partially misled about the history of the machine when you bought it. It just seems there must be more to this than you know about (probably.) Overlaying all that is that the dealer has been in and out of business during the period of interest.

The plot thickens quite a bit reading that work order. You don't suppose this tractor was under water for a while ? In an accident while being transported or ?? At very best the previous owner must have treated the machine pretty strangely.

These things are often like a good mystery story. Look forward to your photos.

Disagree. Permatran is standard MF transmission oil which is much lower viscosity than 75-90WT gear oil

No, it's not.

You are making the common mistake of thinking the gear oil is heavier, because it's 75-90W.

But, gear oil is NOT measured on the same scale as motor oil, which is where the transmission oil is measured.

Both 75-90W, gear oil, and most hydraulic transmission oil, (which runs around 30W), are basically the same viscosity.

Viscosity varies widely by brand. A 30W from one company can be thicker or thinner than another, but give or take a small margin, both are about the same.

You will see this for yourself, if you do a simple side by side pour test.

Kubota SUDT is an exception, which if I remember correctly is closer to 20W.

That could be the problem.

Perhaps someone will know. But, I would think there is supposed to be a way for the pressure to vent.

Good info. I have never seen that chart before. The problem with the chart (or with my memory, one of the two) is that I was basing my comment more on the side-by-side pour test (really in my memory, not actually side by side) and I remember the transmission oil being much thinner than the bottles of "gear oil." Now I gotta go try that.

They are basically the same product, with different additives. And, are interchangeable in many applications.

80w gear oil, and hydraulic transmission oil, are both light weight gear oil.

The transmission oil has more additives. (i.e. wet brakes, and anti-foam).

People have trouble accepting the fact that the 80-90W gear oil is not thick. Because, the 80-90W classification convinces them it is.

You should be able to see it by eye, when you pour them. But, even better, you can do a timed Zahn cup type test, (cup with a hole in it), or a side by side cup, or bottles, with a hole in it, test.

Again, viscosity often varies widely in products of the same weight. But, you will not see a difference that is significant between most of them.

On automobile axle seals that would not be considered a leak or covered by warranty unless a drip is occurring. A "wet" or lubricated seal does have some gear/oil/trans fluid pass through the contact area to keep the seal from wearing. Also on automotive axle seals if the differential isn't venting properly or at all the amount of fluid through the seal will increase substantially. Usually the seal itself isn't the cause of a leak, it an effect of another cause. Excessive bearing play, incorrect fluid, and lack of venting are the most common causes of seal leaks.

Bje56:

Since yours is an early model GC, make sure they installed a shield on the transmission, to protect the filter. The early GC's came without it.

If the front of your transmission doesn't look like the one in the picture below, I strongly suggest you order the shield, and install it. MF part #79026385.

The filter is susceptible to being broken off without it.

Hey Ray66v,
I came across a post a few months ago about this. The local dealer is quoting me $129.95. That sound right? Appreciate the heads up though as it currently does not.
