I just took delivery of a Cummins service manual for our engines. It took me awhile to figure out which manual covers the common rail engines. Even Cummins told me they didn't know and had me contact the company that manages their manuals directly. After getting the wrong manual the first time, me and one of the employees at the manual place figured out the correct one. It's Cummins bulletin 4021271 - Troubleshooting and Repair Manual ISB and ISBE (Common Rail Fuel Sytem) Series Engines. $77. ?? The manual does NOT specifically cover the engine for the Dodge; it covers the "real" ISB series used everywhere else. Many things are the same, some things are different. For example, the industrial engines don't necessarily come with a lift pump (see below), and the gear case is located in back (we knew that). They also come with an air compressor.
It has some very interesting tidbits in it, and it lists additional literature sources for our engines. I recommend the book to anyone who plans to keep the engine for a long time. Here's some interesting info I got from it in just a quick scan over it:
-With regard to the CP-3:
"The fuel that enters the high-pressure pump is pressurized between 250 and 1400 bar for engines without EGR, and between 250 and 1600 bar for engines with EGR. "
-Industrial versions of the ISB have fuel-cooled ECMs.
-Non-EGR engines have no lift pump, EGR engines have a lift pump.
-The fuel connector to each injector has an "edge filter" that breaks up small contaminants that enter the fuel system. [very interesting]
-"Cummins recommends the use of a high-quality SAE 15W-40 heavy-duty engine oil, such as Cummins Premium Blue... "
-"*CAUTION* - limited use of low-viscosity lubricating oils, such as 10W-30, can aid in starting the engine and providing sufficient lubricating oil flow at ambient temperatures below 23*F... However, the continuous use of low-viscosity lubricating oils can decrease engine life. "
-Cold start oil pressure typically will be approximately 100-120 psi.
-The oil pressure check valve opens at 60 psi.
There are lots of other interesting things in here, including color flow diagrams for all the engine fluids.
These manuals can be ordered from your favorite Cummins service center, or the Powerstore (I think).
