Diesel Dragster Hauler getting re-power, CAT 3116 Out, ISL-400 / Jake going in.....

Front mount, and engine shots. Note that the fan center to radiator center is going to be an issue. I may go with electric fans, or build my own fan hub support.

Favorite photo: The ISL logo peeking out. I will build a bumper extension to fill this gap, though. Truck looks OK with the body lift.

Next steps:



Intercooler plumbing.

Wiring. A full day of work or more.

Clutch linkage.

Transmission and driveline.

Cooling plumbing.

Fan drive.

New gauge setup and dash controls for cruise, etc...

More, more more... .

Dang, that sucker is really coming together. Most Cummins motors have different fan drives as options. Higher, lower, left and right also different RPM. I don't think electric fans will work with that much motor. What rear axle gear are you running? Must be about a 3. 00. Also what clutch? Maybe a 14" twin disc Spicer. What size bellhousing did you settle for, it looks bigger than an SAE number 2. Sorry for all the questions, but your project has me excited!!

The highest fan center still won't do it. I have a 11. 5" C/L, and we make a 17. 5" and a 19. 4", but I need like a 24". I am afraid of electric fans, as they just don't do it.



The rear gear is 2. 74, and with the 19. 5 tires and the OD,HANG ON!



Yep, 2 disk 14" clutch, 1 3/4" input, and it is a #2 housing.

Man that thing is lookin' sweeet. Can't wait to see what you come up with for an engine fan.

 

[KBennett]

Lookin' good Scott.



Have you given thought to chopping up the radiator support to lower the radiator?

 

[Will24]

Doh, sorry Scott, didn't know you did the dragster chassis work! I need to move to Colorado, lol, I work for the wrong distributor, I'm ISX and N14 NOW certified, I have a whole page list of cummins training



lol



How is the clearance between the front cover and the rad? Could you get away with using a hydraulic RV fan?



Truck looks awesome though

Thought about that, and the rad is wider than the frame rails. I may end up building a custom rad and CAC, then that would be cool. I think I will take a ISM fan clutch I have, and remount it in the rad center, and build a support plate for it.



The real issue, is the belt length. Poly V belts that long, get pricy and rare.

C'mon out to Colorado, we are always looking for a few good men. Especially those with hobbies like diesel trucks.



The hydraulic fan is not a bad idea, though.....

Scott: We have a similiar truck with Goodyear 245/70R19. 5 wheels. Calulated your speed at 1900 RPM with a 2. 74 rear, in direct. We get 66. 5 MPH. We measured our tires and they were about 32. 25 inches in diameter. Nice project, keep the info and pictures comming. Fred

 

[btanner]

there are several companies now making electric and hydraulic remote mount fans for truck your size and much larger. There was an article in diesel progress about two months ago covering this. I think that electric is a very sound option as is hydraulic. As for the body lift I would try to raise the bumper instead of creating a cover because it'll look a lot better that way.

I goofed. It has 2. 64, and we are using a 12609-B trans. It ends up at 80MPH at 2200, (direct) and 109. 6 in OD at 2200.



Nice cruise point though, in direct, at 75 it is turning 2063 RPM...



It says it will run 95. 8 MPH with the power requirement on flat ground. Hmmm maybe a set of injectors, water injection and a tweak or two... .

 

[sbentz]

Here is a hp requirement chart... .

I am thinking the same. Raise the bumper and add a lower fairing... .

 

[stacerbob]

I must have missed it somewhere. Why the body lift? Whats in the way??

the engine

 

[sbentz]

After getting it in, and final fit, If I did not have the Jake Brake, could have not lifted it. The enging is about 3" shorter in height w/o a Jake.



It is so nice now, and will be easy to work on.

 

[Forrest Nearing]

uhh... don't forget the Jake!!!



lifting the body a little is a SMALL price to pay for an engine brake! I can name about 5,000 people who would GLADLY put a body lift on their Dodge to get an engine brake! LOL!

 

[stacerbob]

I see. I figured there was enough room under there for the motor. So the bodylift is what is making you come up short on the fan drive height?
