hello from europe. i need help. A guy sell this two bell housing from some cummins industrial engines. he says that they fit 4bt and 5,9 6 cilinder cummins engines and that they are "SAE" he explains that I can use them for some of my projects for swap engines to timberjack skidder. can someone tell me is this housing suitable for clark 3 speed transmission or any standard manual transmission from timberjack. thanks

Im gonna bet its 6bt to SAE2 since thats what those engines ran in the f700.  Youll need to take measurements off your trans to be certain which SAE pattern you have.  2 and 3 are most common.  If you need a 3, look into the american 6x6 military trucks.  Thats the only place i have seen them.  They did run cummins 6CTA engines but im not sure about 6bt.  6CTA is a heck of an engine if you can fit it.

Check the tranny bolt pattern.
If the small cummins are like the big brothers, and I assume they are, you will need to use a dial indicator to install it.
Old LT40HD, old log truck, old MM forklift, and several huskies.

at the moment i dont have any transmission where to measure. i liked to have them when i buy a timberjack like 380A with detroit 4 53 clark 3 speed willing to put cummins inside. thats because i ask. cummins engine are pretty common here in smaller trucks and cheap so comparing to detroit i give advantage to cummins for many reasons. other problem is torqe convertor but that's other story. this engines from small truck dont have bell housing to fit clark 3 speed or any other manual transmission

Its funny that cummins is made here and cost a fortune, but cheap in croatia.

Maybe you should start exporting them back to us!

Both those flywheel housings with mate to the 3.9 and 5.9 Cummings as well as the Clark 3 speed (2800).  The starter placement is different than original fwh in a timberjack, the engine mounting flanges on those fwh will not be needed as there were none there on the jacks with the Clark transmission just one mount on the front of engine and the transmission mounts.  Detroit and cummins convertors are different internally because of different stall.   You will need a flywheel that has sixteen or thirty two holes to mount the fiber gear to it.  Most of the cummins in jacks had the 32 and Detroit's the 16. The "C" jacks used a flex plate rather than fiber gear with flex plate bolts accessed through port with the removable plate.

Covered before for another skidder brand

If your diesel supply is of a high enough quality and the electricians are good you might look for a common rail diesel engine for a 25 percent fuel saving to do the same amount of work. i.e John Deere 6 cylinder, deutz diesel, sisu FPT/ Iveco etc

thank you on the converter difference. i have tried to explain this two dozen times, i can't seem to get the point across to most folks.
