GregH Posted March 11, 2010 Share Posted March 11, 2010 I've got an ambulance here with a failed lifter on #1 exhaust and severe wear on the remainder of the valve train components. Taylor Made ensured that their ambulance bodies would not be removed by running their harnesses through the cab, and using only one color of wire (orange). I thought briefly about using the hot wrench on the harness... "I got the engine fixed for ya. Don't know why nothing in the box is working.." But I figured I'd do a partial lift. I didn't disconnect anything not required for engine removal - except for the cooling stack; that all had to go. I stuffed a piece of 4x4 on the rear body mounts, and stacked 4x4 with 2x4 on the front mounts. Two errors - I ended up having to separate the steering shaft to clear the horizontal EGR cooler - found that during the lift. I also found that I damaged the EGRTA sensor - clearance was insufficient at the firewall. I left the hole empty during engine installation. The turbos and the oil pan can stay in place. Now, for stringing the engine up on a chain. I would not have had clearance to use the provided hooks. So, I took the turbo heat shield off and removed the front turbo mounting bolt. I then used a 6.0L head bolt in the same hole, and put the bolt through the last link of my sho-nuff chain. I put a loop in the other end of the chain and started the lift. Turns out that the engine's center of gravity is really close to under the front turbo mounting bolt - so it lifted nice and straight out of the vehicle. Installation was a breeze, too - relatively speaking. I looked over the tools before using them - The bolt should be able to hold a 10,000lb load, and the chain is rated for 8,000lb load. The lift should be easier on the chain than a normal lift because of the straight line pull. As for the threads in the pedestal, they should also be able to support a 10,000lb load - this figure was taken from the maximum clamp load for a 14mm grade 8 bolt. And as for the pedestal, I figured it was beefy enough for this application. It still made me feel uneasy to see the engine swinging from a single point. But I can't believe how simple it was, and how slick the removal and installation was! Three of us pulled it in about 20 minutes after all the bolts were loose, and two of us took 30 minutes to reinstall... Almost made me want to take it out and do it again - it went too quickly!

GregH Posted April 10, 2010 Author Share Posted April 10, 2010 While I was in the 6.7 class, I got a look at the special service tools. The engine lifting apparatus bolts to the engine block in place of the turbo, and features a single eye for a hook on the engine crane... So they want us to lift the 6.7 in this same manner. Of course, the factory lifting eyes hang way out to the sides. They are obviously removed prior to fitting the body.. Quote Link to comment Share on other sites More sharing options...
