I have had two people ask me if my coach is for sale too.  Maybe one day but right now I want to run it a lot more.

Our coach is an '89 and we have three different parties telling us that when we sell to please call them first. That does say something about Foretravel quality and design.

David,

At 47,500, you can't expect it to act like a ballerina. You must have huge brakes. Don't know if you noticed but a research company has been fitting injectors to Detroit 60 series that operate at 160,000 psi with 120 passages on each nozzle. They hope to go into production and get EPA certification. Emissions have been a problem on all the Detroits so this might be a breakthrough.

Thanks folks, you guys run what I think is one of the best motorhome forums on the internet. I've been watching for some time and am always amazed how you all seem to pull in the same direction. Well done! :)

Thanks Pierce, I'll look for a link to the new injector technology. All of the Series-60 equipped wanderlodges are non-egr engines, this includes the LXi's produced in 2003. For 2004 Wanderlodge switched to the Cat C13 engine with it's ACERT technology which was introduced to meet the EPA '04 emissions regulations for on-highway trucks. Happy Motoring! :)

Their video seems pretty optimistic but at that pressure, perhaps the figures are not too far fetched. Here is the link to an article: Green Diesel Corp Fuel Injectors - 160,000 PSI Diesel Injector - Diesel Power  They seem to have it working in other diesels besides the 60 series and claim it can be a retro fit at 5% of a new engine cost compared to 25% for the injection systems on today's diesels. A lot to expect.

I had the coach up to Preston today for an inspection, so decided to stop by school on the way home since one of the janitors is retiring at the end of the month and will be full-timing in a 5'er. One of the teachers also wanted to see it, so we gave a quick tour. They couldn't believe that the coach is 20 years old this month. Then I stopped by the bus garage, and a driver and the mechanic came out to see it. The driver really wants something like what we have. I think he's a couple of years away, but I wonder if we might not have found the next caretaker of our coach. When I first started looking the mechanic suggested I stay away from the two-cycle Detroits, but he seemed pleased with what we have.

Your 6V92 (Silver 92) is not the engine as the earlier "two-cycle Detroits" that he is thinking of.  That engine is way advanced and fixed as compared to the early 6V92s the he is referring to.  The silver 92 did not even need a diaper under it to catch leaking oil like the old Detroit Diesel two cycles did.

After he told me that a couple of years ago, I did some research on the Detroits and found just what you said. As a result, I was not afraid of getting a 6V92 or even an 8V92 (common on the 'Birds that we were considering).

Jo Ann got the plates today and I put them on, so we're completely legal. Can't wait for the first trip!

The 6V-92 is the better of the two, no issues with the rear main bearing, heavier oil etc.

You will love the first trip and will remember it for a long time.

That mechanic probably drove a stick 8V-71 and stalled it at an uphill intersection then rolled backwards causing the engine to start but run backwards. They can really make a mess when that happens. The air cleaner turns into the muffler.

The 6V92 will run backwards too.  The old style 6V92 were also oil leakers.  We had 14 oil stained spots in the dirt at the terminal I drove out of.  That was where the 15 White Road Bosses were parked.  The spot that was not oil stained had a White Road Boss with a Silver 6v92 parked over it.  That particular engine was much stronger that the old 6V92 engines The old engines were green colored if I remember right, and the new ones silver.  6V92 DD Silver engines began with the serial number F83425 any number after that is a Silver engine.

I actually experienced the engine running backwards as I was leaving the refinery one day.  There was a "speed bump" as you pulled out.  I hit the top of the speed bump with my drive wheels and let up on the fuel at the same time.  She rolled backwards while the clutch was engaged and reversed the engine.  I stepped on the clutch but it was to late.  Black smoke just poured out of the engine compartment.  Pulled the fuel shut off to stop the engine, and then restarted it.  She ran fine then.  Had she continued to run in reverse, she would have pumped the oil right out of the engine.

When the DD is running backwards, quickest, best & simplest is just stall it, no reset air box flapper, and only takes a second to restart and go. yup been there when first started driving em DD 2strokers.

Had forgotten all about the flapper box. I never had to use it. Don't think the DDEC will let the engine run backwards but only a guess. Also, pretty hard to get even a mechanical DD to run backwards with an automatic but if it did, it would be a trick getting it to shut off without waiting. The positive displacement fuel pump would turn the opposite direction so when the fuel in the cylinder heads dropped pressure, it should shut off by itself. Now I remember the flapper box on our fire apparatus was used if we got around a natural or propane gas leak. But any diesel would go crazy around those gasses. Turbo seal failure could also cause any diesel engine to run away.  Even a partial seal failure can cause high temps and burn a hole in pistons. I saw a Cummins in a Mack (South American VW) lose one piston completely and early detonation force the edges of two other pistons down on the compression rings. Think the bore was OK and a bit of surfacing would take the broken ring divots out of the head.
