Tony Ingram Posted February 1, 2009 Share Posted February 1, 2009 Well I've figured out my fuel rack problem with the help of Rob and Garth but I have another roadblock now. I removed the old exhaust system which was patched a million times and thought I could simplify it with some new galvanized tubing. The bottom flange that bolts to the exhaust manifold hits the top of the frame and the main airline from the compressor. The exhaust manifold turns down and to the rear at a 45 degree angle. The flange and tubing that was on it was 4" pipe. I bought a new piece and after cleaning everything up, I could not get the flange to correctly bolt up to the exhaust manifold. I want to know if anybody has any pics of the engine and exhaust system. I don't know if the original exhaust manifold was changed and if the 4" tubing is not the original size. Also I noticed the dipstick and oil filler tube had to by pushed over to the driver side to remove the exhaust flange. I would appreciate any comments or pics if anybody has some, Thanks. Actually any interior pics would be helpful also.. Quote Link to comment Share on other sites More sharing options...

Actually any interior pics would be helpful also..Turbocharged Thermodyne series engines used a 4" exhaust that I've seen and worked with. The non turbocharged engines used a 3.5" exhaust pipe. Sounds like it has been modified through the years.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

HK Trucking Posted February 1, 2009 Share Posted February 1, 2009 The bottom flange that bolts to the exhaust manifold hits the top of the frame and the main airline from the compressor.Sounds like the right side transmission mount is broken, or the rubber insulators are completely squashed, causing the engine/trans to lean to the right, resulting in the exhaust manifold touching the frame.There should be no contact there.As Rob said, the non turbo thermodynes (in B models anyway) usually used a 3.5 inch pipe from the exhaust manifold to the muffler. The factory pipe flared out to 4 inch at the muffler end making it possible to use a 4 inch muffler.

vanscottbuilders Posted February 1, 2009 Share Posted February 1, 2009 Tony,Herb is right - check the front engine mount and the transmissionmounts. The rubber donuts are probably shot, causing the reducedclearance issues.The exhaust on our H-63 is 3.5", and the original had a horizontalmuffler under the truck. I don't think that should make any differencein the pipe diameter, though.There won't be any more clearance than you need, but things shouldn'tbe hitting each other.Paul Van Scott Quote Link to comment Share on other sites More sharing options...

Tony Ingram Posted February 2, 2009 Author Share Posted February 2, 2009 The tranny donuts are definitely shot. Where can I get some or do I have to ad lib or have some made?Talked to Barry today at WattsMack. He said they had all of the rubber biscuits I needed. Just waitin to see how long to ship and exactly how much. Hopefully mama doesn't get too curious lookin at the bank statements. Spent a little more than I first told her to get it running but that's half the fun. It was just an uneducated guesstimate at the time anyway.

Bollweevil Posted February 3, 2009 Share Posted February 3, 2009 Paul is right about having your ducks in a row. As cold as it has been, if you have to spend any time in the dog house, you might also look for a big fuzzy dog. Quote Link to comment Share on other sites More sharing options...
Tony Ingram Posted February 4, 2009 Author Share Posted February 4, 2009 (edited) Paul is right about having your ducks in a row. As cold as it has been, if you have to spend any time in the dog house, you might also look for a big fuzzy dog.Fortunately out here in Ca. it's been in the 70's so if I get in the dog house I won't freeze. Figured a couple of Starbucks runs early in the morning might keep the peace. Once she saw my son's smile sitting it while it was running it kind of smoothed things over..
