I worked for a while on offshore tugboats that had huge GM Electo-motive Division (EMD) diesel engines in them. Huge suckers. 22 ft long with the gearbox (5 ft). Each cylinder had 10 liters of capacity. All 16 of them, in a vee configuration. And a turbo as big as a 4 person table. 3500 hp each, and we had 2. Some boats had 2 16s and 1 20 cyl.! Impressive equipment, to say the least!! The turbo whine at the air uptake on the 2nd deck at 800 rpm (850 was max) was deafening. Oh, and fuel consumption? Around 5,000 gal/day, towing. Anywhere from 2-2.5k light. It took 50 gal/day just to run the genset at the dock. So I don't want to hear any fuel consumption whining! J/K

Anyway, they were equipped with what we called "soak-back" pumps for the turbos. Basically, an electric oil pump that automatically kicked on when you shut the engine down. It would keep the turbo bearings supplied with their requisite oil bath. It would shut off after 20 or so minutes. It was a big deal, too, because the turbo housings were magnesium, and could theoretically get hot enough to catch fire and basically melt through the hull. Not a big threat when you are shutting down after docking, but not good when you're on a dead rack pulling a rig with 2 other boats, and still making only 2 knots, and you drop an engine. (actually happened once. Dropped an engine. Engineer runs downstairs to power it back. Damn thing ran away, so he tripped the overspeed shut down. We had to un-hook from the rig at 3 am with one engine. Not good. Soak back did its job.)

So, is there anything like this for our trucks? It would basically be like a turbo timer without the noise and fuel waste. Also, how about a pre-lube system? The EMDs had that, too. I tried searching, maybe there is a more common name for a system like this.

Thanks,

 

You can go to Pre-lube.com there in PA I use it in my truck.

 

Thanks. A google search wouldn't have killed me, huh?

I found this: http://www.prelube.com/, but they are ou of LaPlace, LA. My neck of the woods.

Looks like lots of nice options for the pre-lube.

Any ideas about the "soak back" pump? Only hits I got with google were for EMD engines! Seems to be a trade name for their system. Wondering if anyone knows another name for a similar system for retail use.

If not, I'm headed to the drawing board. Hell, I'm an engineer, I can figure something like that out. Maybe make a zillion dollars...

It was my idea first.

 

http://www.pre-luber.com/ is the place I went to. Good Luck
