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 large tabs on each end that were used for mounting in the donor unit have been removed.

Next, the back cover of the dash cluster was removed and riveted to the front of the center section of the dash that used to hold all of the gauges.

A portion of the old center section was removed to provide the opening for the plug that will carry all of the information to the dash cluster.

And here is how it looks! Note that the new dash cluster slightly overlaps the dash air vents. That significantly complicated things so the decision was to simpify things by surface mounting the new cluster. Some time after the coach is up and running, I may completely redo the dash by removing and replacing all three sections and rearranging the various controls. At that time, I will be able to nest the gauge cluster into the dash. In the meantime, this will work.


This is the throttle pedal out of the donor pickup. It has to be transfered as the Duramax uses electronic throttle control rather than mechanical using a cable. It has the curve in it as it was attached to the firewall and the base had to avoid the transmission hump. In the FMC it will be avoiding the heater instead. Somethings just work out to the good!

It will need to be positioned something like this when installed. A bracket will need to be designed.

The old trottle pedal will need to be removed.

Looking at the phillips head bolts that were installed 38 years ago and now need to be removed! I hope to save the pedal as someone else may need it. I also plan on using those two bolt locations to help hold the bracket for the new pedal.


Same two bolts looking from the bottom side. They have been sprayed with Kroil penetrating oil. May have to pause to let it do its loosening magic (hope it is magic!).

Well, the soaking worked! It took both Larry and I, but we were able to get the bolts loose and the pedal is now removed.

That was followed by the removal of the bracket and the pedal rod. With these three components removed, I can now have a small plate made to seal up the floor.

This is what the floor will look like - no hole. The replacement throttle was test fitted using a wooden block and now I will have a bracket made that will attach to the firewall and position the new pedal properly.
