Hydralic oil in engine oil???

[smittyd]

Some how I have an extra 1 gallon of fluid(seems to hydralic) in my engines crank-case.?Any ideal on how it got there or the problem?I heard it was a rear main seal??Any help out there? Thanks Daniel

It wouldn't be a rear main seal. I is more that likely the seal in the rear of the hydraulic pump.

Jerry ,thanks for your reply.How easy is the seal to fix?Cost alot of cash?Full of questions,forgive me but your answers are greatly appreciated and helpful.. /forums/images/graemlins/ooo.gif

From looking at the shop manual and the parts manual for a MF 1240. That is what you have? It looks like the seal just pulls out of the pump when the pump is removed. It doesn't look to be to bad of a job. You could do it yourself. You will need seal part # 3702488m1 and a gasket part # 3702553m1.

JerryG:

Think you're correct. I know for a fact that older Farmall's had a problem sometimes with the seal between the hydraulic pump on the front of the engine failing and allowing fluid to drain into the crankcase. He didn't say, but if that's where it is his hydraulic fluid level should be dropping by roughly the same amount the crankcase level is increasing. If that is the problem, should be fairly easy fix (you even gave hime part #s).

JEH

They did take your main hydraulic pump off and not you power steering pump?

Jerry they took it off, put a new $650 pump on and still the same problem.Was a rear main seal,tech guy fixed the problem only alot of money and no help from the dealer,was a factory defect and took me down the dirt raod I did'nt want to ride on. /forums/images/graemlins/mad.gifReally shows how people have pride in there products,and support the people that provide them with a living.Guess I'll take it on to coporate headquaters and see where it goes.Wish me luck!I appreciate your helping me Jerry .. /forums/images/graemlins/smile.gif

Is that a "wet clutch" setup, where the rear main seal is the only thing keeping the two oils separated?

 

[JerryG]

It's a dry clutch.

I am confused !!! if it is a dry clutch how is the rear seal letting hydro fluid into the crankcase ???

That is a good question.

 

[JerryG]

What seal are you talking about? As the guys were saying, with a dry clutch you can't get hydraulic fluid in to the engine. If you are getting hydro fluid into the engine, it is from the steering pump or the main hydro pump period.

Jerry, this is what we are talking about.
That is why we are confused.
