Ok where can we get a manual or specs ?

140 bucks for a manual up here in Canada , there has to be some cheaper sources for manuals or specs out there.
Cummins should sell a CD for 20 bucks and not a cent higher. We also need a source for bearings and gaskets and water pumps and alternators besides cummins.

FAQ: Commonly Asked Questions, 4BT Files, Photos, Links, Etc....

original post by fly71h on Yahoo 4BT site;

"The primary difference between an on road and off road engine is the function of the governer. The on road engine has what is sometimes referred to as a speed governer, which does exactly what the name implies. It limits the maximum rpm of the engine and nothing else. Actual engine speed (below max) is controlled by the throttle linkage on the injection pump. If the load on the engine increases, rpm will decrease unless the throttle is opened further by some outside influence. In the case of a truck engine, that influence would be the driver's foot. The off road engine has a load governer. It's purpose is to keep the engine at a specified rpm regardless of load. As load increases or decreases, the governer proportionally increases or decreases fuel delivery to maintain the same rpm without any movement of the throttle. What this means is, when your truck with the off road engine in it encounters a hill, it is going to try to go faster all by itself. I'm not saying it won't work, but it will be very "different" to drive, and could potentially be dangerous under certain circumstances.

original post by Bob Sova on Yahoo 4BT site;

"I agree with you and could not have said it better. You have perfectly described a "industrial stationary engine" in a power unit such as a pump or generator. They are designed to run at a fixed speed to prevent cavitations in the pump or to maintain the hertz frequency in a generator. There are however some non-stationary off road diesel engines that could possibly be adapted to function in vehicles. These would be found in wheeled and tracked tractors. These engines are designed to be run at variable throttle position speeds and the governor is designed to increase and maintain the engine speed only as far as the throttle is positioned. The major difficulty in using one of these engines would be emission certification requirements that our duly elected officials have established for our own protection."

The other giveaway is the on road Diesel will have a EPA tag stating approved for on road use

Note: Cummins referenced part numbers are frequently updated by Cummins so these listed numbers may only provide a starting point for cross referencing.

Cummins Engine Part Numbers to Case Tractor Part Number Conversion System:
Use the Cummins part #'s. Just change the first "3" to a "J"

So as an example Cummins part# 3928405 becomes Case Tractor part# J928405

How Much Does a 4BT Conversion Cost?

There are many variables involved but generally plan on spending as much as twice your minimum budget before you are done:

FAQ: Commonly Asked Questions, 4BT Files, Photos, Links, Etc....

From over at the TDR site, a few P/N's that we might find useful. These are for the ISBe 3.9/4.5L I think.

(170hp, 3.9L) can be flipped end-for-end for front or rear sump (SWEET! ).

Here are some part numbers I managed to get...
Cummins part # (as of 2/8/06):
4897997 OEM oil pan
4896964 oil pickup tube for REAR sump
4898301 oil pickup tube gasket
4897887 oil pan gasket

I have a link that you can download the 4bt manuals in .PDF format.

http://rapidshare.com/users/49NHRE

Password: 4bt

There are two types of Engine Parts Manuals and one Service Manual.

I think that rapid share has a limit on how much you can download for free. You can pay like $6 and get a 24 hour pass to download all you want.
Yes, you have to wait 23 minutes after every single download, if you're downloading free.

Since we have the torque specs, here is a mostly complete list of the fasteners used on our B series engines that the torque applies to..
This list is riped from a 6BT manual, so some quanities (oil pan bolts, injector line mounts) will be difrent, adjust as needed.

If you know of something that is inacurate, or have bolts to add, send me a PM and I will update it
Thanks
