MGB: Clutch slave hose

All right, what's the secret in getting that damned hose off? I gave up on my last clutch job cuz I was able to get the slave off. This time I cant even break the connection at the slave. Any ideas? PB Blaster is on it now. engine is out so there is more room to work but still can't budge it! I am afraid that I will end up rounding off the tube fitting. What's next-heat? I hope not-that seems like asking for trouble. Got to pull the master cylinder too, so I suppose that means the brake master and pedal box, too. I would not wish this on my worst enemy! Any ideas?

You mean the piece that hooks onto the frame or the end that hooks onto the slave??

I have to replace both the hose and the slave. The fittinf where the hard pipe ties to the hose is my problem. The 7/16" wrench wants to open up before the thing comes loose. If I don't back off it will round the fitting for sure, then the whole line will have to be replaced! Damned thing likely has been together for 30 years!

You don't have a wrench for fittings?? You know the hex box end with the peice cut out. I for get what tis called. Either that or cut the hose and get a socket on from the bottom. Stuff like that is a real pain in the a$$!!

Hose wrench I think.

The problem is the nut /bolt or whatever you want to call it that is on the hard pipe. Cutting the hose will not solve the problem. I can hold the hose and the locating nut that anchors the hose to the tab is free.

Get or borrow a TUBING wrench,or visegrips

Proper terminology is a B-fitting wrench, although most part vendors probably wouldn't know what you mean. The "nuts" on both rigid and flex tubing are known as B-nuts. No idea where this name originated.

Could you be talking about a flare wrench? Just bought a set to try out.

If you don't have one get one at sears, 6 point Line Wrench. Tighten the large nut back tight so all your dealing with is the line. Some times the line will be rusted inside the nut. If when turning it the line starts to twist,STOP. Your going to have to use heat or you will twist the line off and have to put another flar in it. That is a bubble flare too. Not a normal flar.

Well, even with a flare wrench, even with two applications of heat, even with four hours of PB Blaster the SOB rounded off! Never even tried to move! Guess that means it's time for a hacksaw on the tubing and another next day air order to Moss! Ever have one of the years when nothing goes right? Wish all I had to worry about is a fat blind date!

AMH-3, when discharged, here.

No, AMH-2.

Put a little silicone grease on the new one. You'll probably be the guy who takes it off the next time too.

Ok, John, I give up!

Aviation Metalsmith Hydraulicsman 2nd Class. 2nd class was as high as you could go in 4 years in nearly any rate when I was in the Naval Air Corps. I made it in three years. A straight Aviation Metalsmith would be AMS-(whatever class).

John,
Same here...AMH-2 after 3 years of 4 year hitch. Hated chasing leaks at night with red flashlight! Remember?

I didn't work nights. had some easy jobs too. Tested pumps on a test stand now and then, shop supply p.o., Shop education p.o., kicked back, read the "Anymouse" articles in Naval Aviation News, made ash trays out of 5" shell casings on a lathe, tinkered with old motor scooters, and had a good time.

Geez John, I'm glad you got that right, otherwise I'd have to give you a ration of crap from another discharged ATN2....we were E5s JD!!!!!

Lots of times I regret not staying in. I always wanted to make Chief and get my special fitting for a coffee cup.

No where have I seen it suggested th at you pull the locking piece out first. It is u-shaped and slides into the hose end fitting to locate and lock down the hose. I don't mean to be insulting, but years ago, I didn't know about them and had a hard time.

As Kelly knows, we had to know EVERY hydraulic component on our aircraft, pumps, actuators, struts, everything, while the Air Force had specialists for nearly each component when I was in. I learned this late, but I could have gone into the Air Force, taken some tests, jump directly to E-7, and have been a hydraulics instructor. I've oftern wondered......What if?

As far as I know there is no such creature on my B. The hose passes through a tab then a locknut screws down to lock it in place, then the hard pipe fitting screws into a set of female threads in the end of the hose fitting. Seems like I have seen a different setup on American cars, though.

Yeah, I wonder too. I had great duty, good division officer (warrant officer), great chiefs, cushy calibration lab supervisor job. Was offered a tax free $10,000. re-enlistment bonus, but figured as soon as I re-upped, I'd get sent to bumf@%k Egypt or somewhere with a real prick as a division officer. So I bailed out. Probably was a big mistake.

i just said hell with it, and bought a new metal line, and installed that with a new rubber line.. after 20 years of corrosion and such, it was worth the piece of mind to me..

Yea, that's what I am going to do, too. My problem,when I adopt that veiwpoint, is where to stop? Got to pull the pedal box anyway to replace the m/c, so I will clean up and repaint everything. That old brake m/c is sure going to look odd next to the new clutch m/c, may as well replace it too. And then even the brake lines are old so maybe I ought replace them too. And then there's that four way connecter and switch, it's 30 years old, too, (and damned expensive). See what I mean, I just can't stop! "Might as well" is addictive! But Moss loves me! Maybe this Christmas they will send me a Xmas card!

D'ya still have any of those ashtrays?

Fat chance...Moss will be waiting for a Christmas Card from you instead.

Just one.

Well as one of Patton's Generals said to the Germans, "Nuts".

Well, don't I look stupid! I remember those tabs from some English car, thought it was a B, must have been TR-3. I just checked the Moss cat., and they don't appear.
Good luck!
