I am about to change my intake/exhaust manifold from a distillate to a straight gas, which looks to be fairly straight forward task, however I thought I would solicit advice from someone who has accomplished this in the recent past.

I guess the main thing is not to break off any of the studs -- I have been spraying penetrate on them for a few weeks now, but they off-ly rusted.

Anything else I am blind to – would be a great help

Chris, Rusty Farmall has a good point in that the studs are often less than perfect once you get the manifold slid off. I would heat the nuts red hot , then douse them with cold water, the sudden temperature change will break all the rust and they should turn easily, do not use much thrust on the wrench, if they won't come easily , heat them red hot and turn them off hot. Even if the stud is corroded it will still do the job. I have seen mechanics braze the studs to reinforce them, rather than try to turn them out and risk breaking them off. Good luck with the manifold swap, your tractor will run much better as you will get better fuel/air distribution with a new manifold....Mike in Exeter Ontario

Sounds to me like you pretty well have it covered. The only other thing might be using a torch to heat those nuts. Also, I have found a couple of times that the nuts come off fairly easily, only to find that the stud is rusted so badly that it needs to be replaced anyhow. You won't know until you start.

Replace the muffler while you are at it and put a rain flapper cap on it to keep out rain. Use anti-Seize compound on the studs before the big socket tightening. Use a new gasket whenever you remove that cast iron spider.

Tighten the studs from the inside out in a pattern. Make sure the gas manifold is clean and tip it upside down and tap it on the concrete floor to make sure no loose rust is hiding in there. You may need to readjust the carb.

The Two things I can tell you is make sure the new one is straight if not take it to a machine shop and have it machined down alittle. Next after running it good and hot let her cool and retighten the nuts. You may have to do this a few times. These engines just love to suck air around the intakes. But thats the only thing I can tell you. JON
