 Need advice on oil leak on rear attachment hydraulics

I have hydraulic oil coming from the oil seal on the shaft that comes out of the Oil Pressure Group 1. This is the shaft that the two arms connect to (one on each side) to raise and lower the rear attachment (box grader on mine). I used the tractor tonight and when I was done it had oil 'flowing' from this shaft hole.

Could this have happened if I overfilled the hydraulic oil? If so, do you think that the seal is actually blown, or will draining the excess oil stop the leak?

 Need advice on oil leak on rear attachment hydraulics

Crash1,

Somebody here will surely be able to help you, but before we can offer any advice, it would be nice to have a tractor make and model number to refer to.

I'm not familiar with some of the terms you've used, such as "Oil Pressure Group 1", nor do I understand which hole the oil is leaking from.

Please provide as much information as you can. Thank you.

Joel

Typically, each splined shaft will have an oil seal associated with the bushing or bearing (where it goes though the housing. My first guess is that one of those seals has ruptured. Overfilling will just make the issue show up sooner rather than later.

 Need advice on oil leak on rear attachment hydraulics

Sorry, it completely slipped my mind. It is a B7100HST. The shaft that I am referring to is the one that the two arms (one one each side of the rear of the tractor) that are used to lift/lower the rear implement. Omn mine, this is an articulating box grader (or what the guy that sold it to me calls a Gannon Bucket). I felt that more than likely I had blown the seals. But, after draining the excess oil, the seals have not leaked all day. I used the tracter to drive approx 1/2 mile up and down my road to repair a rain washout, and towed my utility trailer up and down from it's storage location. In other words, ran it pretty hard, and no further oil leakage. You can easily see the seals in the housing, and there are really no signs of them being ruptured. I am sure that they suffered somewhat from the experience, but it appears that it may take the force of excessive oil to make them leak, and as long as there is the appropriate amount of oil, they may hold. I am crossing my fingers anyway. I will replace them if they start to leak again.

Thanks for the advice and the offers of help.

Normally there is not that much oil around that area so if you don't over fill it again you shouldn't have any troubles.

Operating with the fluid level lower than normal just to avoid a little leakage - isn't a good solution either. But if you keep fluid at the correct level, don't be surprised to see seepage again some day. Especially if you drive the tractor somewhere (parallel to an embankment for example) that puts the deteriorating seal on the low side.

Actually, I only drained off the excess, bringing the fluid level to the proper range on the dipstick. So, I am just going to keep an eye on it and if it leaks I will replace the seals. I have actually run it pretty hard, and on uneven surfaces and I still see no new leakage. But it would not surprise me if it did leak again.

It could be that those seals are designed to keep dirt out, not necessarily to keep oil in. Maybe they don't function well to keep oil in if the oil level rises up to the shaft.

Well, if that was the case, I don't think they'd be called oil seals in the parts manual.

To many technical writers all seals are probably oil seals. Oil seals usually have extra lips for additional sealing power where dirt seals don't. Obviously I could be wrong but it explains what the OP is seeing.
