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.

This is the rear crossmember of the coach's frame. It ties the two ends of the frame together and, with the Chrysler 440, also supported the engine with the two arms that point forward. It will be reworded for this application as the right side engine mount will be directly to the right frame member and the left one will be further to the left and lower. Other modifications will also be made, but the strenghth will be maintained/increased.	We have adequate clearance between the engine and the firewall. This will be increased by about 1/2 inch. Please be aware that while the engine has been located, this has been done so that mounts can be designed and then built. The engine will need to be removed while things are welded to the chassis and some other things are done to the engine. It will then be reinserted into the coach permanently.	The enigne is now within 1" of its final position as to left/right and forward/aft. It may be raised a couple of inches. You will also notice a vertical chain to the left side that goes from a bolt on the engine to the base of the stand. Since the center of gravity of the engine is above and to the right of the crankshaft, this chain prevents the engine block from rotating around the secured crankshaft.	A view from the side reveals that we have enough room to move a foot forward (to the right). Note that "forward" in this discussion is to the rear of the engine as this engine is going into the rear of the motor coach.
The original fuel filter (white object at the left) will be moved down and over for better access.	Another angle.	At long last the engine is slipping into the engine bay!!! This has caused me to recollect a saying that includes the words "... light at the end of the tunnel"!	The transmission has been tightly strapped to the transmission jack so that we can move the engine around and there is no risk of the transmission slipping off of the jack. It has swiveling wheels so it will just follow the transmission.
I needed to design this tool/stand as when the engine is moved into the coach, there isn't any room for the engine hoist to suspend the engine from above. The engine needs to be stable when initially positioned so that engine/transmision mount attachment points can be designed.	..... the jack removed. There is a second set of holes in the upper legs so that it can be pinned at a higher location if needed. The outrigger feet can also be screwed higher or lower to help with fine placement of the engine.	There are holes in the legs such that at a certan point, pins can be inserted as you see here and .....	Now you see why! A small jack is placed between the legs and used to raise the engine up.
