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.

A steel washer was also cut and fitted to ensure that the new clutch pressed against the pulley as it is a press fit.	The new clutch had a smaller diameter threaded attachment so the pulley was dismantled and the shaft size reduced and then threaded to match the new clutch.	(2 Comments) That clutch will not work with the switch in direction of the engine as there will no long be air flow to activate the clutch. Also the air needs to be pushed out of the rear of the coach and not drawn in. This required a change in both the clutch and the fan. Above is the new clutch which will be activated by engine temperature rather than ambient air temperature.	You have seen the fan pulley and the orignal fan clutch before.
This is where the fuel comes out and back into the tank. A fuel injection system pumps much more fuel through the system than is needed to run the engine as the excess flow ensures full availibility of fuel and the excess fuel flow also cools the injectors.	... fuel tank out.

I will need to trim the edges of the cluster and open up the hole in the dash as well, but there is a 1/4 inch on each side remaining between the air vents and the cluster so all is good!	Four screws and the center section simply comes out. All of the wires are still attached as you can see at the bottom of the picture.	Suprise!!! We now move to the other end of the coach and inside to boot! This is the center section of the current dash. As part of the conversion, the dash cluster is also being moved over so that full instrumentation is available and functioning.	(2 Comments) Here you can see the hole where the transmision will slide into. If you look closely at the tail end of the transmission, you can see the slightly rusty parking brake actuation lever between the brake drum and the rear housing.
