Re: Onan 4000 Intake Manifold replacement
Gdetrailer- Thanks for your input, I didn't think to remove the cylinder head (and using the pipe extractor). I did a lot more digging and found the Cummings Service Manual with all the torque specs to retighten the cylinder head. If I can't easily get that small part of the bolt out or if it is cross threaded, I'll just remove the cylinder head and replace the intake manifold, probably be easier and quicker. Thanks again for all the suggestions, this is a great source for info.1.3KViews0likes0CommentsRe: Onan 4000 Intake Manifold replacement
The broken piece of bolt is in the threads by the paper towel is stuffed in the intake manifold. I was able to remove some of the air cleaner housing and have better access to the busted bolt. I may be able to Dremel a hole in the bolt enough to get a bolt extractor on it and see if it’ll unscrew out. Thanks for everyone’s input, it’s appreciated!1.3KViews0likes0CommentsOnan 4000 Intake Manifold replacement
Hello all, I am the second owner of a 2010 Forest River SandStorm 210SLC with a Onan RV QG 4000 EVAP Spec: K. The previous owner had a lot of carb issues and would replace the carb every year or so. During one of his routine carb changes, it looks like he busted the end of a bolt in the intake manifold leaving only one bolt holding it together. I'm looking to replace the intake manifold but can't find much info on how it comes out. Its very tight and was able to loosen it but its pretty locked in with another parts of the generator. (I'm looking to replace as part of the threads are stripped as well due to his effort to fix) Has anyone had the pleasure of replacing their intake manifold on their Onan 4000? Thanks, Brett4.4KViews0likes12Comments
