Thanks for all the complements gents.

Today I tackled the shut down cable. I started off by making a little bracket for under the dash. I bent it out of some scrap 3/16" strap.




I am using a solid wire push pull turn to lock cable meant for an airplane. I had to find a way to get the power if you will to the fuel shut off lever. So off I went through my derelict odds and ends and found an old military quick disconnect throttle cable end. This cable is threaded on one end so I had to have a way to lock in the cable wire.

I started by chucking a 1/4-28 bolt in the lathe and put a hole clean through and chamfered the ends.






Next I cut down a small brass plug. This will be used to lock in the cable like so.




How the end goes on the fuel lever.




I then took a 5" piece of 1-1/2" x 1-1/2" x 1/8" angle.




And made a bracket to hold the cable.






A little mock up for both ends.






And finally painted and installed.




Fuel on.




Fuel off and locked in place.




Well folks, I'm out of parts again. I should have some batteries soon, and the cable to make the 2/0 battery cables. Until next time.

 

so clean.Dumb ? why shutting off fuel?Diesel thing

 

Not a dumb question. Most people, even gas engine mechanics have a very vague idea how a diesel really operates. Buy pulling the fuel shut down lever you turn the engine off. It cuts the fuel to the rack in the injection pump shutting the engine down, just like shutting off the coil in a gas engine. It basically kills the pressure build up required to pop off the fuel injectors. In this diesel there are no glow plugs, computer, or computer controlled injectors so shut has to be done mechanically.

 

International 826 tractors and others shut down that way.

You are a daggum fabricatin' genius! This thread will go down as one of the best ever for sure!
I can't wait for it to run.

 

Thanks.

Running truck soon, just gotta wait for the ups man.


And...for all you guys that wonder how the injection pump on a diesel works. This is a really good video of how the p7100 injection pump operates.

 

Wow no glow plugs,no pre heater

 

They come with a grid heater which is like a mesh screen in the intake manifold, but it's a huge restriction so a lot of guys delete them.

 

And the grid heater is not needed unless it's really damn cold. I have mine in but no battery power to it yet. That's at the bottom of the list. I have a block heater that'll be nice and toasty before I fire it the first time.

 

When my buddy built up his 12v the grid heater was the first thing to go. He's had no winter issues and we obviously get a much colder winter than you ever will.

 

I left it because I hunt well above the snow line. The deer zone I hunt doesn't close till December with snow on the ground. It gets rather cold up there. Just don't want to deal with cold starting a diesel. Much easier to push a button to warm up the intake.

 

Nice bracket Co, blends out of sight once you painted it.


On a separate note, there is no measurable difference when removing the grid heater no matter what anyone tells you, its not a restriction. The only real restriction on a cummins is the head itself, but then that's why you compound turbos and make it take air

 

Yeah I read somewhere they tested the grid heaters out V.S. in. It ended up being about a 1 p.s.i. difference in boost pressure. I'd rather be able to start my truck anywhere and not have to worry about relying on the block heater.

Either way I know I can make 500hp and around 1000 ft lbs on a stock head. How much more power and torque do you really need on a street truck. I think Betty will tow 10k plus just fine.

 

I dont know if this is off topic,if so say off topic and move on:Why do some diesels have glow plugs,and this cummins doesnt?excuse my ignorance.thanks for the education

 

It's all about heating the intake air and compression ratio. Older diesels were down in the 14:1 area, my cummins 6bt is in the neighborhood of 17:1 same for newer powerstrokes. As a result those older diesels had to have those glow plugs to fire off when cold at a warmer air temp. Newer diesels can cold start down into freezing temps. The glow plugs and grid heaters really do the same job and the computers force them to operate even if they are not really needed. As far as one having them and the other not, probably just a design choice. With the cummins that's 6 less glow plugs to fail, less wiring & less maintenance.
