That is a great article on GM diesels Frank ! Having worked on the 71 series I too can testify to it's durability and power output. To bad "fuel emission standards" finally killed it.

It was turning into an argument about superchargers and turbo's. Since the Detroit Diesel did indeed use a "supercharger" (mostly Roots brand ) it was getting pointless to argue anymore.

I know, since the engine will burn it's own oil. That still has nothing to do about the engines lower then average compression. The Deutz 2 cycle engine does not use a blower as most do not.

My point was that the Detroit Diesel engine was a low compression engine and the use of Turbo's helped bring up it's power level. Also other 2 stroke diesels do not have to have a supercharger to be able to run.

I agree with you Jason about the compression and efficiency, that is why I'm sure Detroit Diesels are actually low compression and without there superchargers would not start. But I believe the higher compression reached by the use of Turbochargers gives us more power. You always sacrifice...

Wow ! This took over an hour to scan and upload these 5 pages. I wish I had faster internet service. In interesting side note I found in the TM while waiting. The multifuel engine is allowed to consume 1 liter of oil an hour at 2600 rpm. I thought it was interesting.

Blasted! I just spent over 1 hour uploading 10 pages and the only thing I see is two ! Sorry Brianp , I'll try again tomorrow. There is two styles of injectors and I posted how they where to be rebuilt. I also had the rebuild info on the Three Finger Clutch assembly. The LDS engines had quite a...

Brianp I agree with your assessment about the engine. There is one thing I would like to bring up, most all modern diesels have 4 valve cylinders now. So I believe the potential of this engine has not been reached regarding air intake and exhaust. That being said, I have posted some more pages...

I think your right Jason. The "IHC" DT466 is looking better everyday. The "Rockwell" differentials will be with us for years. So we're looking at the brake system and engine transmission units. I bought 2 gasket sets today, so as long as nothing major blows I'll be good for awhile. But when it...

Gerhard, did you see on the data sheet that there is 3 cams listed. 2 High profile and 1 normal.

How do you delete pictures ?

The year is 1964. Some more pictures to look at.

That is really interesting. Why would the manual give two different specs ? Maybe there where two different cams, but after time they decided to use just one that fit generically all engines.

The cam is also different between the engines.

I totally agree ! That's why I'm going with making the engine as strong as possible (within reason) and tweaking the injection system.

Kinkos wanted $300.00 to do it . I already asked.

I'm not in the "lets see how much power we can make" camp. I'm in the lets make some decent power and good reliability camp. I think balancing the crank and rods would be a good step, but first I would have the rod ends checked and machined with new 12 point bolts installed. Then I would attack...

I have the manual "TM 9-2815-210-35" in paper. I thought of putting it on the site but it's 500 pages and I would have to scan each page twice.

Wrong, cam engineering can help any engine. As a diesel mechanic I have seen massive improvement from "IHC" (Ford Engines), "Cummins", and even "Cat" over the years. There is even a difference between the "LDS 456-1 " and the "LD 465-1 " in cam opening. As far as increasing the durability by...

I think spending money on a cam would be more beneficial. I'm also wondering if you can get roller lifters for these beasts. New cam, roller lifters, that should go along way in making more power and reliability .
