I guess I should write some articles for the tech section here.

Most of those I type from memory, and have found much better ways to do them.

Check out the article on how to convert a 7.3 glow plug system to manual control.

First paragraph has the engine temp switch part of the glow plug control circuit, which is totally wrong.

Run a ground wire from the momentary switch to the frame?

OK.

Yes it will work, but it sure is a lot harder than it needs to be.

Besides, if I write articles about how to do everything, what am I going to do every evening?

 

I've been a OB.net guy for a couple of years. I have it set as My Home page. And I believe it was Me that asked Dave to go over and fill them in on his 20 PSI build.

The IDI guys are every bit as good as they are here. They poke a little fun at some of the goat boys, but it's all in fun.

I never read any negative comments about Dave, but I'd almost bet they were from a newb. He, and a couple of peeps over at OB.net have taught Me more about IDI's than any other source.

They have a much larger collective knowledge of the IH IDI than any other resource on the net. A couple of them are working/retired mechanical engineers, that have built amazing engines also.

Just go and look at their manual over ride GP controller. Agnem built it using a common computer chip. Allows You to use the original controller, and a push button switch.

There is much more IDI info readily available there, than here.

 

Dave,

Wait, you said on the blog to take off 20 thou. Don't you mean 40 thou?

Hmm, not replies to your remarks, I'll stick around to see how this turns out...

 

i dont think a tech section is nessecery, we have a tech section we post and dave s answers thats good enough i think. i mean we dont have to copy what they do

 

oilburners is down

 

Working fine for me.

 

I have read that hackers have been crashing a few sites here lately.

I actually like no tech folder.
It keeps the forum alive in my opinion.
And troubleshooting, hard to do that in an article.
To many bits of info that can change the direction you want to look in when trying to find a problem.

Tech articles can have you changing parts that are not needed, many of them may not be cheap parts.

I stayed at 20 thou for cold starts.
Mine gets a bit contrary around zero without being plugged in.

 

Is there enough meat in the pistons to do 40 thou without cause for concern? Low temp starts aren't that much of a concern for my 6.9's new intended purpose, winter wheeling is fun, but, I don't do very much of it at all, and if I do, there's always the quick coupler fix.

 

I did 20, and Dave did 40 and we each did a 30 thou over bore. Both seem to be doing fine.

EDIT: I guess I could drill a hole through one of the old damaged pistons just for the helluvit to see how much meat there really is.

 

Icanfixall @oilburners has all the info on pistons.

Quote: "About shaving the piston tops. It is "possible" to mill them any amount but.... When I needed to do this I bought a set of Mahle 1441800WR std. These are the big pin type. They were way too tall for the block macnining I had done so... I talked to the Mahle engineer named Eric. He told me to buy a low comp piston and mill no more than 18 thousands off the tops because the pin is machined 10 thousands higher in the piston so that alone will lower the piston in the bore. The stroke stays the same too.... Otherwise the top compression ring will suffer from the heat because its now closer to it. All.. And I mean all the Mahle pistons, even the original ones removed from my 89 motor have a crown thickness of between 560 and 580 thousands. So there is plenty that can come off but outside of what they recommend you are on your own"

 

The most I know of is 120 thou off the piston, still able to run just fine after you get it started.
Twin turbo high boost pulling engine.
Plug it in and glow plugs to start on a 70 degree day though.

That should have the compression dropped to around 15.75 to 1.

I have started mine at -6 without it being plugged in, but it was not a happy engine.
Several afterglow cycles with the manual glow plugs to keep it running.
