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.

As you can see, all of the backend and exhaust pipes are off the coach. Now the assessories are coming off and the connecting things are being undone and labeled.


The computer is out. Here you see the wire loom hanging down. Now need to open up the sealed passthrough to the engine compartment and stuff the wire back into the engine compartment. Getting the silicone to unseal is difficult!


Currently, the 440 has an Edelbrock MPI fuel system. The computer that runs it was installed inside the coach to keep it cool and dry. Now it has to come out.

Here is a picture of the steering wheel. As you can see, it would be nice to have all of these controls on the steering wheel instead of switches on the dashboard.


And if you look closely at the lower left portion of the assembly, you can see where the six pin connector plugs into the throttle assembly. The other end connects to the engine computer. We will have to add about 25 ft to these wires since this will be attached to the front wall of the coach and the engine's computer will be in the rear of the coach.


One of the parts we are using is the throttle pedal assembly. Since the Duramax is a fully computerized engine, the throttle is electronic and has no cable to connect it to the engine - just six electrical wires.


The floor mat, which was in excellent condition, has been sold along with the seats to another person. The donor truck is a 2006 GMC Sierra 2500 4x4 and if you want any parts we are not using, now is the time to speak up by emailing me.


By having the complete set of shop manuals for the donor truck, we are able to read up on how to remove the various parts without destroying them. This is being done to make as many of the parts as possible avilable for sale to recover a bit of the the cost of the donor truck. This center console has been sold to a person in LA.


And the needed body control module was found buried behind the guage cluster. It was placed into a sealed plastic bag and set aside.

Here is Eric removing and varous parts. Note the labeler on the floor next to him. Each time a connector was unplugged that we may need it was labeled so when the wiring harnesses that we need are extracted we will not loose track of what each plug is to be plugged back into.


Another view as Eric works his way into the dash. We need to retrieve the body control module for the guage cluster to work properly.


Here you can see that the center console has been removed along with the radio, heater controls (electronic) and the dash guage cluster.
