Having a tough time trying to remove the 6 studs that hold the intake/exhaust manifold on. Tryed heating them with a torch and rocking them while hot and cold won't move. Trying to be carefull so I don't break-em off. Haven't tryed the $20 stud removal tool yet. Any one have a suggestion? I am going to take a break now and drink some beer before I break something.

Hi, I haven't read what the others said, but I have an H Farmall that must have had the same studs holding the muffler adapter to the manifold since it was new back in 1939. I had to remove it to put on a new one. One stud broke and the nut on the other was 3/4 rusted away. I bought some PB Blaster from Pamida, I beleave Walmart has it too. In just 2 days they screwed out. I kept spraying them when I would walk past and give a little tug with a pipewrench. I didn't force the issue but they came out in 2 days.

I first broke the old manifold away from the studs with a hammer, then heated the head with an ACETELYENE TORCH and turning them out with a small pipe wrench. I can't say wether I did any damage to the head, but I only used enough heat to get the job done. You have to have enough heat intensity concentrated in the proper spot. A little heat for a long time will not be as effective as a lot of heat for a short time. Check NORM'S TOYS for a new manifold if you need one.

After the manifold is off, I have had the best luck with vice grips, placeing them as close to the head as possible. If the manifold is still on the head the stud usualy twists off just back of the nut if you don't pry sideways on the stud.

Dick I first tryied the vise grip as close to the head with no luck. I then heated the stud with the liquid wrench and tryied same procedure, no luck. I am thinking of heating the stud then letting it cool repeating this a few times then put the wrench to it and see what breaks.

I have never twisted one off with the vice grips but there is always a first time. I have on older cars but not on a tractor. I just took the studs out of a CA that two of the nuts twisted off but the studs came out ok. The tractor had set out for years.

I had the good fortune to have a friend to borrow the stud pullers from, I think they're worth the money and I now have a set of my own.

My experience is the same as Dick L's. Vise grips always work for me. "Real" Peterson Vise-Grips; I cannot tolerate any immitations! I have three different style stud pullers, but I haven't had to resort to them yet on WD or WD-45 manifold studs. Incidentally, When I put them back together, I use stainless steel washers, brass nuts and "never-sieze". It seems that I have to replace the gaskets every couple of years and this saves me a lot of heartache. Brian G.

I have seen this done once: Heat the stud and head around it up, but not too much. Then, use a squirt bottle full of water (ice water is better), and squirt it dircetly on the stud next to the head. I have just used a small bucket of water for lack of a squirt bottle. It "shrinks" the stud quickly, breaking the rust bond it has with the head. I bought 18-8 stainless steel threaded rod out of McMaster Carr, with washers and oversized nuts to match, all made out of 18-8. 316 alloy is better, but more expensive. After a couple of years, it still looks like new, and will still come apart like new. Good luck! www.mcmastercarr.com
