Edge also offers the EZ to fit the 3126. Good for about 40hp or so.

Sure, take it out and put in a DT466. I have a TopKick w/the 3116, basically same motor but its mechanical not electronic. That thing is a dog but i was able to turn up the fuel rail for more power. I feel for ya man, to my knowledge this is the only POS motor Cat makes.

Not quite..........the 3208 makes a better boat anchor than anything else.

In stock trim yes, but crank on it a bit and its a decent engine. Got one with 350K on it and cranked up a bit and it runs like a top!!

Then again, a few of the forklifts at the mill have 3208's in them and they are real dog turds. The only saving grace for two of them is they have more gears than engine...

Their a throw-away motor really, once it's time for a rebuild just chuck it and do a repower. They also have a nasty habit of the injection pump gear getting welded to the pump shaft when things go south. Thats real fun to get apart then.

They have their place I guess but their are alot better choices out there.

Not to hyjack, but what about the 3408, my uncle had one in a green peterbilt when I was a kid, that thing sounded Bad Ass!

thanks for the replys guys if this was my truck i'd get one of those and put on it but since its the company's i dont see them spendin the money on it at all

as fas as putting a dt466 in it i dont think so. we have two trucks with those in them and i can pass them pulling hills around here and my truck weighs just as much if not more....i do like the dt466 will turn more rpm tho

If you have a 3126 passing a mechanical DT466, then something's wrong, or its power is rated real low.
