Sorry I forgot about the 20 different ways to screw up a good (3406) engine before the killer C15. On another note look closely and in some 3406E engines you can see the Detroit Diesel logo on your genuine CAT injectors. My money is on a 270HP 1674 in his 1974.

 

Haven't been on here for a while; been laid off and can't find time to surf!! I have not driven her home yet- still need to buy batts!! Also scattered my rear end on my dodge, so life has been GREAT!! Thanks for the info; I will check for a tag.

 

oh yeah, and it is a turbo; we had the intake off when it started, and I STILL have dial tone!!!!! What a noisy mother!

 

Yeah, brain f*rt - 3208's in my head, 3408 on my fingers! Loved that motor - tried to find one to put into a pickup - too heavy.

 

Not a big thing brother... I had to deleat my input on the D343.. Could not remember if it is the old D8 Cat engine....two versions of it. counter bored and deck plated...Whew........Had to think there abit.. LOL

 

And BTW other than ones Googling the info......... men.. Were showing our age!!! LOL.. Most of the younger ones dont know what we know. And its our job to help out with what we know. Can't take it to our grave's boy's !!!! Dont know about you, but I enjoy sharing info.. Most of it hard learned...

 

Just a little help on the dozer engines The D8 used a D242 And the D9 used a D353. I would know I did about 6 inframes on them this year so far. Bill

 

old 988a's,824's,834's used the 1674 also I never realized it was put out for a truck motor. I plumbed one up for a jaw moter on a 54" crusher. it would chomp rock!
figgered it was just a detuned 1693 for heavy equipment.

 

I hate to hijack this thread but I'd like to thank guys like you. I'm a 2nd year heavy equipment tech apprentice and I love it when a veteran in the trade gives me info and tricks on how to do stuff. My foreman does that a lot with me. I try and be like a sponge, soak up all the info that comes out of him no matter how relavent it is or isn't.

 

I guess I don't know what to say other than Your Welcome..................WE old boy's don't share info...Its lost.. Books don't teach a MAN everything....

 

I had an 1693 with twin turbos in a 1980 KW W900 that was speced out at Wyoming Machinery in Cheyenne. The engine dyno-ed at just over 600HP and 2000 ft lbs of torque. This was a kit Truck we assembled in our shop in Omaha. Ran 3.33 rears with Spicer 5x4 with double over. Cat did make factory 1693's with twin turbos but they were stationary engines for oil and gas wells and electrical generators. 1693's were overhead cams which is why the couldn't run a jake brake. We had Cats in most of our trucks and ran Cat retarders on all of them. We bought 1 KT 600 and kept it about a year before getting rid of it. Was a money pit and only got about 2.6 mpg. Very heavy also. Had great luck with our 3408's and got about 4 mpg, same as we got on the 1693s and 3406s got about 5mpg. We ran out of Omaha to Shakey and the Gay Bay (Turbo City).
