Oil Line Removal

[Cipotifoso]

As much as I have tried, using PB Blaster and Large wrenches, I *cannot* get the oil line to budge. The oil line rotates CCW from it's initial position until it hits the bottom of the case - then I'm stuck.

I'm trying to turn the inner bolt (red line) relative to the outer bolt (blue line). Is this outer bolt part of the oil line or will it rotate on the line?

If the inner bolt breaks free, as I'm loosening it relative to the case, won't it tighten up into the oil line if the oil line is held stationary?

I just don't understand how these parts go together, so I'm not sure which direction each hex bolt should turn relative to each other.

Any help would be appreciated!

The inner bolt is a fitting to the case, the outer bolt is on the oil line. You need to hold the inner bolt while you unbolt the outer one to remove the oil line.

Might help if someone holds the oil line still with two hands so it doesn't rotate with the outer nut when you try to loosen it.
If the oil line turns with the nut and contacts the case it will try to twist sideways making the nut bind on it.

The outer nut should turn freely on the oil line fittings shoulder and like someone said earlier, use another wrench on the inner nut. you don't want to hurt the threads in the case.

The least expensive thing to do is cut the line as its near impossible to get a wrench on the inner flats.
Sometimes the outer one will spin on the line and get the inner one out.
When you put it bsck together, lock the inner one tight, tight and antiseize the hose connection, lock it down snug but dont abuse it

Just had the same problem. I put a wrench on the little nut and then rotated the tube clockwise while holding the wrench still, which in effect was the same thing as loosening the big nut.

Good luck.

I got it off! The nut put up a good fight (substitute "nut" for "bolt" in my first post). In between having to make preparations for a 4th of July party, I managed to get a little time to make progress on the teardown. After reading all of your posts, I re-attacked the problem. I finally wound up putting one (crescent) wrench on the inner nut and rotating it around until the wrench contacted a block of wood against the case. I then took an even bigger crescent wrench and pulled up (ccw) on the outer nut with everything I had and it finally broke loose. Once it's apart, it's easy to see how it goes together with the adapter (inner nut). Thanks to all for your help!

I recently took this apart on my car. As you can see from the first picture the nut on the left is part of the hard line. At the end of the hard line are threads. The nut on the right is part of the hose assembly and screws off the hard line's threads.



Using a crescent wrench on the hard line's nut and a crow's foot wrench with a breaker bar on the soft hose these came apart very easily. I bought a set of crows feet because nothing else I used seemed to budge the nuts.

My previous post is a bit vague so hopefully this will clear things up. The nut on the left is part of the hard line, and there are male threads that extend beyond the nut. The nut in the middle has female threads that thread over the hard line's threads. The thing that sort of looks like a nut on the far right is only used to attach these metal parts to the rubber hose. You don't put any tool on that. Use your tools on the two nuts that have threads.

Cipotifoso-

The outer nut is what retains the pipe against the inner case fitting, and the inner should be tight against the eng case. Now that the inner fitting is loose, you need to find a 32mm THIN wrench to hold it while you loosen the outer nut with your 36mm wrench.

Try doing this with a oil return tube still in place as many of us have done. At least you have room to get in there to get it apart.

Don't forget to use a new crush washer on the eng case fitting and use a socket & torque wrench to do it properly. You might also consider Lock-Tite thread compound to keep it secure in the case.

Be sure to use anti-sieze compound on the threads & inside face of the outer nut when putting this pipe back in place.
