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 correct it, out came the engine one more time! Please note that anti-rotation chains were always attached as we were lifting with the crakshaft pulley and, if it was not restrained, the block could and would rotate around the crankshaft. This could damage the engine and personal safety.

And here is the problem. The welder miss located the steel plate that holds the right side motor mount. The top of that plate was suppost to be even with the top of the frame.

However, at that point a problem was noted in that the engine was slighly rotated to the right.

It was time! The engine was inserted and bolted in.


Exhaust temperature sensor is in place.

Here Larry is watching Mark work with a Dremel to create a hole in the exhaust manifold shield.

Here Larry is watching Mark work putting the exhaust manifold back onto the engine.

One of the exhaust manifolds was removed and drilled and tapped for an exhaust gas temperature sensor.


And on the other side, the engine mount is welded to a plate which is welded to the frame.

Here is the plate that was discussed earlier with the engine mount from the donor welded to it.

The rear crossmember has also been completed. What used to go straight across from one frame member to the other now dips down to go under the engine as the Duramax is slightly longer than the old engine.

Here you see the slight offset of the mounting slots. The holes are slotted to allow for aligning the transmission to the differential when the time comes.
