Y-pipe removal

[sfwjesse]

yes i agree that that is what should have happened. I did get it cherry red, but unfortunately the bolts are just too rounded now. I wish i had cut the bolts though the wheel well...didn't realize how easy it would be to drill out the manifold once the tranny was out. Now i have a cut y-pipe. I am going to remove the remaining exhaust and bring the y-pipe to work and have them weld it. If we jig it up just right we should be able to save it...if not ill have to spend the 100 for a new one at auto zone.

what i have done in the past was cut the bolts with a torch... then once you pull the tranny out you can crawl back under and "blow" the remaining bolts from the manifolds an just replace with new hardware.. was easiest way i could do mine.

Had my tranny out twice (93 4.0L 4x4 manual) and both times I found it was easier to hit that y-pipe with a sawzall and take it to the muffler shop for welding when I was done. Most shops won't charge much to reweld your pipes.

i just did my clutch a few months ago and dident need to take the y pipe off.

Yep, that's exactly what i did. Fortunately i work at a company that has a machine shop that does welding, so i think i can squeeze in a "govt. job" with one of the guys during lunch break. the hard part will be aligning it so it goes back in perfectly. I figure i can match up the cut marks from the sawzall pretty close.

Just an update. Truck is all back together and driving nice.....needs some more bleeding but at least it can shift now. I got the y pipe welded at work. Everything fits, but the bracket on the cat does not align very well with the bolt on the tranny mount that it is supposed to be underneath. It is off by about 1". If i had this to do over again, i would have had my welder tack it, put it up underneath, bent it to where i wanted it, then had him weld it solid....FYI the welding with TIG was tricky....he could only go about 1/2" at a time due to heat build up...one time he punched through.

Anyways everything is leak free, and i will just forgo the cat bracket for now. Maybe make something custom later if the exhaust starts shaking itself apart.

94 Explorer 4WD - Clutch job

Im having to change the clutch in our 94 Explorer and I just have a couple questions:

Does anyone know how to get the y-pipe unbolted?

And how do I disconnect the "tranny line"(?) The gold fitting that goes into the tranny near the top on the drivers side.

Also, we live in a smaller town and I was thinking of leaving my cats off, I would't be questioned or have to do an inspection at any time. Would this have any "bad" effects on the Explorer's performance?

Im already halfway through taking the tranny down, so any help would be appreciated.

Thank you.

This may be way too late (and probably not applicable), BUT on my 86 bronco II and 86 Ranger, I unbolted the body mounts and jacked the entire body up to get the transmission to clear the y-pipe. Could this not also work on a 93? If so, sure seems a lot easier than messing with broken manifold bolts, torches, welders, etc....

This was answered in another thread where you posted the exact same questions. I would like to point out that though the Federal law against tampering with your emissions controls is largely unenforced, it is still illegal to do it.

Way back when, I got my A4LD out of my Ranger without taking out the y-pipe, everything after it came out though.

When I pulled the Y pipe on my 3.0 '93, I used this technique and an impact gun and the bolts came right out:

One thing I found was that the socket that best fit the exhaust manifold to Y pipe bolt was a 9/16 inch socket. The 15mm was too big and the 14mm too small. Every other damn bolt on this truck is metric and I was surprised to find the English standard wrench worked. I'm not sure if this was the factory messing with us or if rust made the bolt head smaller when metal flaked away.
