I just ran across this thread, Though I would add some pictures .

Detroit 8v92 Silver spec, You got to love an engine that has both a supercharger and a turbo



Or the Twin Turbo Cats



Great thread, Just blown away by some of the stuff fellow inmates work on

I have been a wrench for 31 years and have a great library of engine pictures, I will need to scan them and post them up.

When I am not working on the big truck engines I do these for relaxation

Ah, the memories. I drove a coach (Prevost w/ 8v92) for a band for 18 mo. Went out to train with the team on their way back to home base. Previous driver was a nickel/dime operator who looked for the cheapest possible way to keep the thing running. Previous overhaul was poorly done and he let it go to 325k. 150 miles from home base in Reading CA, things go catastrophically wrong. So wrong there was a grapefruit sized hole in the side of the block.

New engine.

1 week into the tour, Ive got more oil in the AM than the day before . Definitely not normal for this 2 stroke beast. Turns out the shop hadn't done the fuel return jumpers right and it was dumping fuel into the engine sump.

10 months later in CO rockies, blew the turbo apart. Couldn't make 65 to save my life. Thankfully that was under warranty. Don't know much of what happened to it after that cause it was no longer my problem. whew. Those were just the highlights - lots more insanity on that 18 month jaunt.

Still, gotta love a 9 l motor that can make 475 horses pushing a 23 ton beast around at highway speeds.

The last job I was at , we serviced band buses. Got hooked up with a leasing co in Nashville.Whenever a bus was in the area for a show, The driver would show up and we fixed anything it needed. I have done anything from satellite t.v. systems to major mechanical work on many a band bus. And you drivers were the best. You guys never wasted my time, knew exactly what you needed done. It was fun, at the time. With the short turn around time available to get some of the issues fixed, sometimes I really had to hustle

That was the whole truth. I wasn't a professional driver before the gig, but had to get there quickly and learn to diagnose problems and have parts waiting *wherever* I could find open service bays on my ONE day off per week.

Thanks for the reminder of how GOOD the shops were to fit us in on little/no warning.

Do your engines run on raw field gas?

Any one else ever seen the SR71 Start Cart at the Dayton Air Force Museum?

Two Buick engines had to be warmed over to make the required 800 horsepower needed to turn those big ram jets

It runs on the same Natural Gas (Primarily Methane) that it's compressing on the pipeline. The fuel is ran through metering then regulators before it goes to the fuel manifold. This engine is low pressure fuel injection, each bank of cylinders (3 on each side) have a common fuel rail that depending on load usually runs around 15psi.

I think I missed that yours is a compressor rig on a pipeline, not a suction rig for a refinery. My mom worked for ARCO and retired as a plant operator. At Drumright, OK, the engines were suction rigs, pulling in raw gas from the field for refining. The engines ran on the raw gas, not the finished product. I was wondering if yours did the same thing, but they're not doing the same job.
