    Fix or replace?

    I have a 1980 MCI and it has a significant air leak. I have located the exact location of the leak but am unfamiliar with the bus air system parts.
    I traced the leak by taking my portable air compressor with 100psi and connected to the c...  more

      Jeanette & Emery Leraand Looks like a pressure protection valve, not very expensive to replace. My bus is older, but uses such a valve to restrict air to the park brake tank until the main brake tanks are at 75 psi or more. Also have a second one that restricts air coming out of ...  more

    A little HELP, please! I have a 1989 Bluebird All American FE gasoline school bus conversion with an Allison MT643 transmission. I arrived in Fargo, ND Sunday for the Sugar Beet Harvest. I limped into Fargo and my tranny died. I will be working the harves...  more

    An update on our bus/engine. We are basically into a complete in-frame overhaul at this point.  Heads are being rebuilt and we are getting new cylinder kits and new main and conn-rod bearings. Fuel injectors are OK and will be reused. Having the DDEC I...  more

        Bruce & Linda (Omnibus) Thanks, Frank.  I know you live close, and volunteered to do that, but did not know you had actually stopped by.  I am very pleased with Brandon; good guy to work with, so I appreciate the recommendation.

      Curtis Man... what a job. Please keep good notes in case I ever have to visit this with my Prevost DDEC. (ugh) You are brave my friend. BRAVE!

    Chuck and Dawn :
    Several friends have asked why I have been tearing the various systems out of our bus and redoing them. Perhaps a few pictures will help explain.
    Start batteries instead of deep cycle for house
    #2 cables to inverter instead of 2/0
    No fuses between ba...  more

      Ed & Judy Glucky That's the way to do it. Rip it all out and start over again the right way (your way) !!

        Bruce & Linda (Omnibus) Yes, as long as you know what you are doing, which it sounds like Chuck and Dawn do.   :)
        • September 12
    • Chuck and Dawn
      Bruce & Linda (Omnibus) Yup, we did the same thing.  Our conversion did not have some of the problems you described, but the house batteries were just large/heavy paperweights, and the pair of inverters where old, modified sine wave models, and did not work very well. ...  more

      Chuck and Dawn Bruce did you choose 24v so your alternator could charge while running down the road? We will be staying with 12v house system and considering various methods to charge same while running down the road. Hide 1 Reply
      • Chuck and Dawn
        Bruce & Linda (Omnibus) No, we have a separate ZENA 24V alternator on the engine for charging the house batteries when traveling.  I did not like the idea of tying the wet cell chassis batteries together with the AGM house batteries and then letting the engine alternator an...  more
    • Chuck and Dawn
      Chuck and Dawn Turns out my cables will be short enough to allow 1/0 instead of the 2/0, but 1/0 is still way heavier than the #2 that was in there. Considering the undersized cables, the lack of fuses or other circuit protection in critical areas, and the fact that the...  more Hide 1 Reply
      • Chuck and Dawn
        Bruce & Linda (Omnibus) Sounds like you have looked very carefully at the system with a critical eye.  The fact that you see these problems and plan to fix them is a very "heads up" approach.  Enjoy the work, I did!   :)

      Bruce & Linda (Omnibus) I had not noticed the AC junction box before. Nice idea; they do not give you a lot of room inside the inverter/charger for the AC wiring.

    Been crazy busy with modifications to plumbing and electrical systems on the bus. On our purchase trip we had to deal with unpleasant odors on the way home and the culprit appeared to be the kitchen sink and dishwasher drain, vent system. Since we were re...  more

    • Chuck and Dawn
      Butch & Fonda We too fought tank odors, especially when driving, with the driver's window open. The Airflow Dynamics of the Bus, cause a negative pressure zone, immediately behind the nose and would draw the air up from the rear. We changed the vent stack caps, to som...  more

    Just put 2400mi on the old Flxible to Boston Ma. Conway NH, North Conway NH, Twin Mountain NH and home. No problems, ran great. Did the tourist thing with the train ride thru the White Mountains and the Cog Railway on Mt Washington. We recommend the Cog R...  more

      Dan Aldridge How are the hills going to Boston?  I've considered that trip, but my Flxliner isn't a fan of the mountains.

    • Ed & Judy Glucky
      Ed & Judy Glucky Going to Boston was not a problem. Going to Twin Mountain NH (Cog RR) then across Hwy 302 and down I91  to Hwy 9 w  was a lot of fun. I was down to 1st gear many times up hills and around curves, some parts it was like being on a two track.&nbsp...  more

    Our bus conversion is out of commission for a while; anti-freeze in the oil pan is never a good thing.
