How to do a tuneup on a 8V-71

It occurred to me that not everyone who might be interested has seen this...  Enjoy!

This is taken from the DD service manual.

Are you all done your engine? At the tune up stage?

Interesting, it covers the same material as my manual, but is laid out differently and has a different list of injectors and timing specs.  I found this a lot clearer for some reason.  I am just at the stage of installing my jake brakes, resetting the jake exhaust bridges, changing the fuel bridge tubes, etc.  I had several sticky injectors so I ran solvent through them and they freed right up.  I'll be going through the steps and checking the entire tuneup, but since my engine is new old stock remanufactured I expect that it is going to be pretty close on everything. 

Funny with a job like this - on Sunday I spent about 4 or 5 hours working on it, I spent about 45 minutes actually doing work that won't have to be redone, an hour doing trial fits that will have to come apart again, and about 2 and a half  hours plus washing parts in the parts washer...  I did manage to install the flywheel and the new pilot bearing, those won't be coming off again anytime soon!

I got the last of the clutch parts from Luke today, so I can now rebuild the clutch cover plate, and put that on.  I got the seal for the alternator drive pulley so I can put that on.  I found a "short" 3/8" NPT plug for the compressor so the power steering pump will fit under it (makes sense to MCI guys who have changed the compressor) so I can put the power steering pump on, finally.  I am just about to pull the governor top off the old engine so I can swap over all the air cylinders and throttle controls, and take the jake brake buffer switch/high idle control off  (I only take stuff off the old engine when I am just about ready to put them on the new engine, that way I don't lose things and forget where/how they go, and the old engine makes a handy storage place for all it's parts).  I took the old blower cover off, with the emergency flap, and sent that to Brice today, that counts as work I guess.

After I get all that done and ready, the nearly final step will be to mount the turbo on the side of the engine, and make the exhaust and intake plumbing work.  I guess I have another solid fifty plus hours to go on this.  I have around fifty hours in it so far, but I've been working real slow.

When I overhauled and turbo'd the 4-71 on the Courier 96, it seems half my time was spent scraping and cleaning parts. I can relate to your experience. Installing the turbo and building intake and exhaust piping takes time. Time looking at it and visualizing. Time getting parts that fit into each other. Welding... Etc. I did a boost gauge by running an air line all the way to a pressure gauge at the dash, starting with a lenght of hydrolic hose from the intake near the turbo to the fire wall, so it would withstand the heat. Works well. A pyrometer would be nice too, but I didn't do one. Not really necessary. I have one in the 5C, but wouldn't miss it if I didn't. These engines don't get hot enough to worry about.

If I lived close to you, I'd visit you and give you lots of unsolicited advice and drink your beer, lol...

Clifford is that in print or on cd. I would like a copy of it if possible

Hard copy Don I'll get you one did you get the service truck yet ?


good luck

[Don Fairchild]

No I did not get the service truck, It sold for $55,000. I don't have the money for that. I have been looking at a couple of Pete 377's that the aunt of a friend of mine has. Her husband had a small trucking co and he died last year and now she wants to sell them. So I need to sell my bus so I can build a service truck.

Thank you Eagle.

You all are welcome, I just did a reverse search of the tune-up link.
Kind of a disappointment some of the links are dead.
