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. |

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. | 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. | 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. | 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. | ||
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 .... | .... 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. | 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. | The cooled air then comes across the top of the engine compartment and drops down and into the stock intake system. | ||
You can see how the hoses that carry the intercooler coolant from the right reat across the top the engine compartment and over to the left side. | The coolant then goes into the top of this small radiator and back through the pump and then back to the bottom of the intercooler. | Split loom covering has been added to the hoses to avoid wear to the hoses from the door being opened and closed. This location allows the system to draw the coolest air possible. A fan will be added to pull the air through the radiator. | Two things were needed. The first was a place to put the second battery as this engine uses two batteries. The second thing was to devise a means of supporting the large muffler and exhaust system. Using the Uni-strut material which was available, a small platform was created with a beam underneath which would give a place to hang the muffler. | ||
