Brad,

That's why I call him a neophyte. Obviously, he has very little "real world" experience with ANY diesel engine. Most of the 3408s we saw had cracking problems in the seal bosses for the liners. I saw no broken cranks, but we only did a couple a year.

If i recall , our 1568 ran on 4 cylinders until you really needed the power. Check this out.

I read an article recently that it was not for fuel economy, but to smooth out the idle.

Very good two part story on that tractor ; you can probably get the 2 back issues :

Plus, they've had a few Steigers in there

That's not surprising. I had a guy come to the shop that had the pushrod break through the rocker on a IDI 6.9 and it was just a few miles short of million miles and had never been apart.
