engine and transmission removal

This is how they are assembled. Engine and trans already bolted together when it is dropped into the chassis. Engine is always way heavier than trans. As long as you have the proper overhead lift for the weight you should be fine. Hopefully the original lifts are still bolted to the engine.

 

I had the experience of being tasked to pull and replace a C12 out of a military vehicle. The motor threw a rod and put a hole in the block. Know this particular truck had a up armor kit on the cab and plates covering the drive train. I HAD to pull the cab because the technical manual stated it was necessary. It was really only necessary because the amount of time it would have taken to disassemble the armor and re install it. Long story short yes I used the manufactures lifting brackets and a extra chain to rig/level out the motor and automatic Allison transmission together. It was also necessary to use a tag line to prevent the motor and tranny from swinging all over the place.

Cab off, Motor and transmission out. It wasn’t a big deal pulling all that apart. It was a big deal tagging all the airlines and wiring harness. Took 2 days start to finish.

So go ahead and pull the hood off that anteater. Cooler, radiator, fan and get after it man!

 

pull the hood, radiator, fan etc. and start pullin. we always used a good sized forklift, a long 3/4" plate boom and some heavy duty chains to pull ours. but you know what you have at your disposal, so make what you got work for you that will be easiest. good luck.

 

dont pull the cab--thats just extra work and extra cost
you can pull both together as long as you have a leveling system on your chain--
or else just pull them seperate--that would almost be easier--truck doesnt have to be very high to get transmission out---probabely dont have to raise it at all---you can rent a tranny jack pretty reasnoble

 

it is possible, we used to remove hood, radiator and intercooler, but IMHO, it is easier to drop a tranny first, becouse I'm sure you will find some clutch pats worn and anyway engine and tranny must be separated.

There are many ways to drop a tranny, use truck lifter and, tranny jack ore sometimes old tire...

Why I do prefere drop tranny first? it is so easy to damage cabine, windshield, with tranny, belive me, no reason.

 

Had never seen a block spray welded before, wouldn't want to know the cost, but cool to watch.
