This weekend I am going to remove the manifold of my farmall A and replace it with a new one (Existing one wore a hole through it). I have been spraying the studs/nuts with kroil hoping that will help. I have a new Vinson(?) manifold for replacement with gaskets. Any tips on the proceedure would be appreciated. Thanks. Otis

My Super-A manifold came off with out any trouble. I had it sand blasted, milled, painted it with 1200 degree black paint, used new nuts and washers to reinstall it and it really looks sharp now.

I just replaced the manifold on my H this past weekend. All went well. I didn't need an impact wrench or anything. I used a Black & Decker polisher called a "mouse" to clean up the surface after removal. Put on the new gaskets and made one to fit the carb connect. Bolted her on and torqued the nuts to 50 lbs. Now she purrs like a kitten. The manifold is now the cleanest and best looking part on the whole tractor. :-)

Have fun and good luck!

Otis, You may end up using an impact wrench on those manifold nuts. Unless it was off recently and put back on with anti-seize on the threads, you can expect some of the studbolts to turn out of the head. I'd have new studs on hand just in case. Worse thing that can happen is you twist off a bolt in the head. Good luck. Hope the Kroil has helped. I think it is great stuff.//FB

Got it off no problem. But apparently it was removed before, because it had 5 brass nuts and one steel for whatever reason. My father has had if for 35 plus years and it must have been done prior. The new "Vinson" manifold made in USA definately is not OEM. 2 places that were not flat for nuts, and the 4 places for spacers were not milled to thickness. Also some other minor details I don't know the answer too. The carberator flange holes were not equally spaced and the gasket for it did not fit until I filed it to size. One other minor detail, the 8 inch exhaust pipe coming out of the manifold is not perpendicular to the manifold. Has a bit of a list to it. Got it installed though. Looking forward to getting some hours on it. Next project is to get the sickle up and running. Thanks to all who have replied and read this forum. Otis

Today's Featured Article - Restoration Story: 1964 JD 2010 Dsl - Part 2 - by Jim Nielsen. Despite having to disassemble the majority of my John Deere 2010's diesel engine, I was still hopeful I could leave the engine-complete with crankshaft and camshaft-in the tractor. This would make the whole engine rebuild job much easier-and much less expensive! I soon found however, that the #4 conrod bearing had disintegrated, taking with it chunks of the crankshaft journal. As a resul ... [Read Article]
