Ok I heard that a Ford F-650 dumptruck with a 5.9 Cummins engine has a dual disc clutch that will work in a Dodge truck? Any body Know?

 

I don't think the F-650 dump truck comes w/ an NV5600...

A source has told me the F650 dual disk the basis for a Mitchell pulling clutch. They use different weights then that application. PM me for the contact information.

HTH,

Well I heard the same thing. What little research I have done it seems like a F-650 dual disc clutch has a 10 spline 1 1/2" diameter shaft, and the dodge is a 10 spline 1 3/8" diameter. The F-650 clutch only costs around $350 so if we knew what year of a F-650 might have a 1 3/8" shaft or if the clutch could be modified easily this would save a lot of money. I have access to a machine shop so modifications would be pretty simple I think. Any Ideas?

 

Just find an 1 1/2" 10 spline input shaft

 

The F650 and F750 use the full commercial engine with the SAE bell housing. Has a larger flywheel, starter is on the other side, has mount pads on the bell housing.

I can't tell you that there is not a Ford clutch that will work in the Dodge, but I would doubt it. The source is probably going by the fact that it is the same engine (block) I have one in my truck, but have used the Dodge bell.

I have distant plans of a Roadranger in mine, that would be the same clutch and flywheel.

 

Let me see if I can shed some light on this subject for you.

The F600 pressure plate is a 13" and carries the same bolt pattern as the ETH pressure plate. The clutch disc is 1 3/8" spline. The Mid size Chevy has the 1 1/2" spline. The problem lies in the dampening portion of the clutch disc. There are a few manufactures to choose from, Lipe, Long and Spicer. Spicer is well dampened but thickness is the problem. Now, you have to choose one that is strong enough to accept the torque of a diesel. Remember, the F600 is a gas engine. A few clutch companies have tried to use the different disc configuration from the gas engines in the diesel without much success. If you look at TST's webpage that would be the Lipe style. Feel free to give him a call and ask him how many broke apart in a short period of time. You really don't have to look too far if you would like to find a clutch cheap. Hell, give me a call, I will sell you the 13" Long pressure plate just like the Mitchell but for the F600. This pressure plate comes stock at 1600 lbs. of plate load with ***** on the levers and 2000 without ***** on the levers. The stock plate load on the Cummins pressure plate is 2850. Mitchell's pressure plate uses special springs to increase the plate load to 3050 lbs. I will also supply you with a disc to fit the cover that is 13" with 1 3/8" hub. I'll give you both pieces for $150, brand new, your choice of design. If it doesn't work, will you be mad? The reason why I said this, is now we need to deal with lever heights. Should we set them like in the Ford or should they be set for the Dodge? Disc thickness, should we put the buttons on that go with the Ford or should we accomodate the thickness to make the clutch work properly in the Dodge? Should we worry if it slips, or should we worry about the disc center breaking? If any of this happens do we warranty it? Do we pay labor? NOT A CHANCE!!

Folks, it's not as easy as grabbing something that appears to line up and put it in. I don't want to sound arrogant here, but if it were that easy everyone would do it.

I tell you what, I will help you out with the part numbers. Local part store....
Pressure plate - CA 0386 Price ranges from $60-90
Clutch Disc - CD 0629 Price ranges from $50-80

Give it a shot, but I promis you are not the first to try this.

All I know is that the engine I am building will need a clutch from a Semi!!! Or something about 25 inches in diameter to hold the power.

Peter this is going to be your project.

Don~

 

Don,~, You're crazy. I think you musta tripped on a stray injector body and fell over that fine line between genius and insanity

Peter, thanks for good clutches and a better explanation.

I look forward to dealing with both of you in my future "Quest for Torque"

All, it was a nice thought while it lasted

Thanks Peter! I figured the final answer would come from someone who's invested their lives to helping us get power to the road.

BTW - I'm liking the higher pressure plate load this time around. It seems a lot more controlled and precise than the old 3400# load. It's much easier to engage/disengage and more forgiving in traffic.

I told my local driveline shop about your clutch and they seemed very interested. Seems like there will be a couple more disappointed EEP customers that will be heading your way. Of course, that was after selling me a new rear driveshaft.

Don, you're a crazy man! I wouldn't know which part of the truck to tear up first if I had that much power!

Thanks Peter for all the Info.


Just to clarify are all the clutch's you speak of Dual Disc clutches? I was told that some of the larger F-series Diesels used dual disc clutch's.


I am a newbie here, does Peter actually work for South bend?

 

Well, in way I guess you could say South Bend Clutch works for Peter. I think thats the best way to put it.
