Target 550 Update 199: Installing the coated blowers into the liner. One of the photo's caption mentions that although the blower cases are magnesium, they still weigh about 150 pounds each. Installing them was a bit of a challenge, not only because of weight, but because they're a tight fit. But the T-550 crew was up to the task and now they're in.
The photos show how special bolts/guide pins were made and how they had to wrestle 'em into place.
Here's the link followed by a couple of extra photos:

It looks to be a well-engineered project. Good on all of ya!
