oil leak

[dobyg75]

my buddy has an oil leak inside the cab where the 6x6 lever is is it supposed to have oil in it and how do i go about fixing it?

 

[gimpyrobb]

Uh, on the floor? That isn't the 6x6 lever.

 

[dobyg75]

no its the lever that engages the front axle the line that runs to it is leaking oil

 

[gimpyrobb]

That line "should" only have air running through it. Does he ever drain the air tanks? Could just be built up condensation.

 

[gimpyrobb]

Has he followed the line? Maybe oil is comming through the firewall and getting on that hose some how.

 

[dobyg75]

not sure but the weird thing is that it smells like gear oil could the front axle be venting through the line?

 

[gimpyrobb]

No, that line switches in the axle at the transfercase. I guess maybe the vent could be plugged and pushing the gasses back through the line. He is in for one hellofa treat if he tries to work on that switch in the Tcase. No room to move at all down there. Sounds like he needs to take it apart and do some cleaning. I don't envy him at all.

Ha! Mine did the same thing! I cycled the switch several times and it cleaned itself out. Not doing it anymore. I wasnt sure if steep inclines and rough riding somehow contributed.

Air tanks clean and no gear oil smell. Not sure of the cause, and I know that most things dont fix themselves...Right now it's not an issue.

Just waiting on more stuff to break!

idk he lives on a mountain he engages the front axle on the road up so he doesn't distroy the road could this be a factor?

Do you know the where abouts of that plugged vent on the transfer case is?

On top of the transfer case .

 

[99nouns]

Are you talking about this one?



Wow This is what came out of above indicated coupling when I removed it.



How it got there is a question of matter.

I just replaced my upper transfer case oil seal a few weeks ago and put new universals on the short shaft while I was at it. The new seal has started leaking. I should have inspected that darn vent while I had the covers off. I wonder if a non-functioning vent could cause the seal to leak? The top seal is well above the normal oil level in the transfer case.

My truck has a leak coming from up on top of the transfer case as well. I can't see it from underneath the truck anyhow, so I intend to pull the in cab access panel to see what is going on.

 

[skinnyR1]

I suspect that my leak is from the transfer case vent. Is this a common occurrence?

Here is a picture from Hanks Deuce's website, that reflects where I think mine is leaking from. When I say "leak," it is just an oily mess on the transfer case, and a drop or two on my driveway.

AAAh my transfer case doesn't have a vent

 

[XchaosX]

I pulled out all vents in my axles, tc and transmission. I ran a vent line to to them all just avoid this issue on both my trucks.

 

[skinnyR1]

So you run the vent line to the intake? That is what is recommended?

 

[XchaosX]

Yes, that's what I did and don't see problem with it. Some recommend against that and install a small filter on end.

I taped a barb into the top of the air filter canister (pre filter),
It works great.
