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 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.	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.	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.	(3 Comments) 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.
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.	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!	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.	We are getting down to the engine itself. This is what you see when everything else is out of the way.
There are a LOT of things to disassemble to remove the engine and all of its control systems.	Our work surface was improved when a friend brought over about eight 4'x8' pieces of 1" thick plastic that we could lay down. This created a nice, clean, slick surface for us to work on. Thanks Anthony!	At this point, the driveline and all but one of the connectors to the engine and transmission are disconnected. Getting very close to engine/transmission extraction.	This picture of the right half of the firewall will give you an idea of the existing rat's nest of wiring that was created at the factory and then doubled in complexity over time as various things were added and removed from the coach over its 36 year life. That will all be removed.
