squirrel cage

This is the HVAC blower motor and fan from a GMC. I'd always heard the fan called a squirrel cage. Now I know why. I've also heard it called a hamster wheel, but I never found evidence of a hamster... though I did find a mouse once.

national security

My friend Lewis bought a military auction HMMWV (humvee) engine... 6.5 liter diesel.
It came in a big military crate, vacuum sealed with a dessicant bag, ready to be drop shipped from 10,000 feet.

well, sort of.

I guess they found a problem and that's why it was for sale.

We made it run inside the crate. That was awesome.

Comments are under pictures. The right sides of the pictures got cut off but if you click on them they should come up in a pop-up (disable that blocker for now).

HUGE intake manifold! There's an EPA sticker which mentions a national security emissions exemption. I'll try to get a pic of that later. done. click here for sticker pic

We ran 24V to the injector pump (help me out here Lewis) and 12V to the starter. 4 batteries in all.

...about the starter. The military crate needed slight modifications to accommodate it.

This is a couple weeks later. One of the cylinders had low compression so we put it on a stand and started tinkering.

This is bad. The rod bearings are toast and what you see in the above picture is the crankshaft with about 0.125" of metal missing from one of the rod journals. This is bad (bears repeating)

But the rest looks almost new. This is good. There are lots of good parts here. Lewis is keeping me posted of the progress.
