cat V-series engines

[GreenGiant2]

In the mid 80s what models were v-8s. 3408 and 3208.was there others.

[gearhead204]

I think there was also a 36 series but I have never personally seen one, I don't think the 33 series was ever in a Vee configuration. Farmer should be able to answer this for positive

and then theirs that bigun don't remember the # but our asphalt plant and crusher each had one to run them . its a skid mounted genset and would fill one half of a 40' dry van, they were a low rpm eng.

9-0-nuthin............I mean 903.

Cat makes numerous v models though not for highway trucks anymore. They make 3500 HP V's for locomotives, generators, mining trucks and other construction equipment They also now own EMD Locomotives and their line of v engines 2 cycle 645's and 4 cycle 720' s

[GreenGiant2]

This would be for a truck

9-0-nuthin............I mean 903.

That's a Cummins

[Superdog]

They made a 3412 V12 that has found it's way into a truck or 2. A friend of mine was building one when he died,never got finished and don't know where the pieces went. It was going in an extended hood,extended cowl W900.

[ranchhopper]

I think some of the new locomotive engines cat produces are up to 5000 horse power.

That's a Cummins

Dangit, I knew that. See what happens when you get back to work from a week off? My brain is fried......that is what is left.

[farmer52]

Back in the day....3208, 3408/12, 3508/12/16, 3612/16 were V-engines. 3606/08 were inline engines. There was never an inline 3500 series.

Larry...Mike is correct...a 903 was a CUMMINS.

Tell the boss you need some time off to collect your thoughts!

D379 is a v8. When i was a kid i hauled one genset on a c60 chevy rollback... it didn't want it

[6368]

cat made some other v8 truck engines before the eighties. the 1676 comes to mind. there was also the 1140, 1150, 1160 medium duty engines which are related to the 3208.

[GreenGiant2]

A guy I know said he has a v-8 cat from the mid 80s. Only has 100 hrs.on it. He doesn't think it's a 3208. Would be nice if it's a 3408

[bullhusk]

Cat 1676 340 HP BAD NEWS, (1960's) I remember them as a kid! I think Cat replaced all with the 1693 & 1674's

BULLHUSK

[gearhead204]

wasn't the 1674 the same as the 1693? the 1693 was the industrial version, and the 1674 the truck eng. I have only worked on the 1693's so I'm curios

[j_martell]

This would be for a truck

Maybe once lol. 645 & 710 are the displacement per cyl and available in V-12-16 & 20.....

I'll have to re-read the book, I think those are both 2strokes with different injection systems....the 4 stroke used a different numbering system.....

[theakerstwo]

A 1693 was a larger engine than the 1674.Both duel over head cam but the 1674 was same size in weight as 1673 which was for runner for the 3306. But was rated only at 270HP

[gearhead204]

ok thanks Glenn, now that you mention it I have seen a old kw with that smaller inline 6 forgot all about it till now, I was only remembering the 3306

Although the 1693 was a DOHC engine, the 3406/3408 engines were its replacement. And yes the 1674 was the forerunner to the 3306. I don't remember the 1674 being DOHC.

[GreenGiant2]

thanks for the repiies, will see what happens

[theakerstwo]

Yes the 1674 was a duel over head engine and if you have worked on them much you may remember that there was three or four bolts on the head of the rear cover below the head that would adjust the back lash in between the cam gear and crankgear at the rear.You could loosen those bolts and move the idler gear for more back lash.

[6368]

Haven't had the pleasure of adjusting the valves yet, but i did have the 1674 powered Brockway out today. Only had four ton of coal (hope that will last till spring) on. It sure ain't big power but i guess it will get the job done. i thought i took an engine pic when i had the fenders swung out but i can't find it.

[farmer52]

Not sure about the 1674 (before my time at the CAT house) but the 3306 was a bullet proof engine. Not like the early 3400 series. The late 3306 DITA truck engine was rated at 350hp. As for the 1693....a guy told me one time, remove the fuel screw from the pump and HANG ON.
