    Yep, the gauge is basically a long bar (around 2' long or so in this case) that has a arm on each end that reaches over the ends on the bolts, The top end is fixed, the bottom end has the micrometer built in. It can be a pain to get it in the dimples on the back side, sometimes a combo of feel and a inspection mirror :-)

    Here's a example of a small bolt stretch gauge, ours doesn't use a dial indicator (micrometer instead) but functions the same, only on a larger scale.

    Do the compressor pistons run on the same crankshaft as the engine?

    Yep the engine and compressors share the same crank shaft. The throws on the crank are wider where both the power rods and compressor rods connect. The compressor rod (Green Arrow Below) connects to the Cross Head (Red Arrow), the cross head converts the reciprical motion of the crank shaft into a linear motion to drive the compressor. The compressor piston rod (Orange Arrow) connects to the cross head then goes through a set of oil wipers (number 7) to keep crankcase oil from escaping around the rod. It then goes through a set of pressure packing (number 6) that prevents pressure from escaping around the shaft and finally connects to the compressor piston (Blue Arrow).

    You'll notice there are compressor valves on each side of the piston ( number 3), these are double acting compressors and compress gas in each direction of the stroke.

    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 :evil

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

    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.

    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. :eek1

    New engine.

    1 week into the tour, Ive got more oil in the AM than the day before :huh. 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. :freaky

    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 :happay

    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. :puke1

    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.
