The Dieselfication of Coach 1046
Author: BigRabbitMan (Show all albums)

This album is dedicated to following the process of Coach #1046 being converted from a 1976 Chrysler 440-I with a 4spd Allison AT540 transmission to a 2006 GMC Duramax LBZ turbo diesel with a 6spd Allison 1000 double overdrive transmission. There is a companion discussion thread in the Mechanic's Corner section of the Forum area of this site.

The intake air piping has been completed. Here is where it comes out of the turbo and goes out and back to the water to air intercooler.


.... here are the ones on the passenger side. When the coach is removed from the jack stands, the axels will be approximately straight out from the differential.


While under the coach, a bad drive axel U-joint was found so it was decided to repalce all four of the drive alxel U-joints. Here are the ones for the driver's side and ....


It was convenient that the donor coolant overflow/pressure tank just fits right where the old radiator was. NOTE: Upon final fitment of the radiator, the pressure tank shifted to the left just under the edge of the cowling.


Remember all those wires in all those long harnesses. This is what it has been reduced to for this application as only the operational things are left.


As discussed earlier, the vacuum source for my brakes no longer comes from the intake manifold, but from a mechanical pump run by the serpentine belt. Therefore, I was able to move the vacuum manifold that separates the front and rear brake systems down under the propane tank. I was also able to add a vacuum tank that will give me a reserve of vacuum should the engine stop. I will now be able to stroke the brake pedal several times after the engine stops and still have full assisted braking.


While the generator was going in, Eric continued sorting out the wires. Notice all of the little white spots. Those are tags that identify what each wire does. Those that are not needed are being clipped off and removed.


Its in!!!


Again, here you see Mark on the left and Larry on the right. This time it is the generator going back into the coach after having been converted to run on propane by Larry.


I made up two #6 cables that allow me to shut off power to all the chassis 12 systems if I so desire. The bottom switch in normal operation is closed and feeds power from the battery to the chassis functions. If it is open, then the coach chassis system is de-energized and there are no phantom draws on power such as computers, etc. The top switch has the lead for the house batteries attached to it. That switch is normally open. When it is closed it interconnects the house and chassis systems should it be needed.

The tube with the pressurized and cooled air goes across and down and into the engine. The reason for the "V" shape to the path is that in the donor vehicle the air comes from below and the section attached to the engine cannot be changed. The black section normally points down, but I was able to rotate it so that it points upward.


Now the tube leading from the intercooler has been added.
