Thanks for the compliment. It represents much time and $$. It’s happy hooked to a sled or going on a long tractor ride with others. It plays well with others!!

You can see the tractor on you tube as IH 686 rolling smoke

Send me your email address and I'll send photos and videos

Sounds like a money pit to me.

Tractor is essentially complete. It’s been hooked to sled a number of times this summer. We pull in a gear slightly slower than road gear. Horsepower is mild compared to many but that was by design. If I want to take it on a tractor ride it’s OK and will do it this weekend. Never enough HP. We think the final drive will sustain more HP so we may seek to increase it substantially. It’s been a lot of work with some missteps along the way but fun. And that’s why we did it!

I have a IH 666 that I have shoehorned a DT 467 in frame. Engine has 13 mm head with BW S300 turbo, water system and more. Clutch is 3disk Leaman unit. Tranny has all new gear ratios except 1 st and reverse being the same. Diff has had the needle bearing treatment We are just a couple days from being complete and then off to the paint shop. First hook is a couple weeks away. Tell me what I missed.

It’s on a pulling tractor that requires different ratios

Looking for a company that can make gears for a 666. Also need to needle bearing diff assembly.

The engine I’m referring to came out of a 5288, hence black. That engine is reportedly stronger than earlier models. That would put the vintage at about 1982 or later.

I’ve been told that a “black” 466 is stronger than a “red” 466. What’s the difference and where was it made stronger. Have a DT 466 in a 666 nearing completion. It’s been a tough assignment!

I'm not that sophisticated, I'm still counting teeth on gears. But I'm learning.

When twood described high gear as 19/1, what do those numbers represent?

I've been advised a GT 42 turbo might be a good selection. Is that HP adequate to spin a GT 42 with a low A/R number?

For the time being, I'm going to stop at 500 HP. Thinking 360 fuel delivery with appropriate supporting devices should supply that goal. I've concluded the 466 will live in that environment. If not I'll deal with it at failure time, hoping it won't be catastrophic.

Where would I find a reputable engine builder? I'm in north central IA

What's involved in fire ringing? Is it like a major overhaul where the pistons and sleeves are removed or is there an easier method? Initially planning to stop at ~ 500 HP and pull in 7500#. Utilizing 13 mm head in rotary pump for about 360 fuel delivery.

At what horsepower do I need to firering a 466?

Thanks, I'm going to use Atlas for new gears in the second and third slot. Thinking one gear faster than fourth and one gear slower than fourth unless someone steers me in another direction. Haven't decided on the tooth count. Been getting lots of good suggestions on this site. Th

What are pullers doing to strengthen the differential assembly on a 666?

Thanks. That's what I've decided to do for the same reasons.

When you install a turbo on a 666, in my case with a DT 466, what do you do about the fuel tank being in the way?

Is it a direct bolt on with the oil lines fitting or does it require some fabrication?
