Plan on using a Cummins 4BT in a large irrigation pump application. Will probably need to run a PTO to a jack-shaft and then belt drive a 1.5:1 reduction up to the pump (Engine 1800 rpm : Pump 1200 rpm). Unit will run continuous at about 75HP for several days at a time. Any idea on who might already make an adapter plate for a PTO output from the flywheel?If no one makes an adapter plate, where can I get dimensions for making my own to bolt up to the block?Thanks and God Bless!
Engine: Cummins 4BT
Nothing. New Industrial Application.
Hi,The B series is used in many pump and other industrial drive applications, however the OEM's that I am familiar with make their own drive units, or they are part of the pump.Is this the type of drive you are looking forhttp://pec-clutches.com/catalog.html?page=8The flywheel housing is SAE standard. For a 4B the flywheel housing is usually SAE 3, although a customer can spec whatever they wish, they are interchangeable.SAE 3 specifies a flywheel housing bore of 16.125" (409.5mm) and 12 bolt holes on a PCD of 16.875" (428.6). Cummins use metric threads, the bolt holes are M10x1.25 - 25mm deep.Post your engine serial number and I can conform that your engine has an SAE 3 flywheel housing, or you can measure it if the bore is 16 1/8" its is SAE 3.The SAE size may help in your search for a drive unit, SAE is a standard so an SAE 3 flywheel housing is the same size on Cummins, Cat, Detroit, Deere, Volvo etc etc, and anything made to fit SAE 3 will fit your engine.With the flywheel it gets a bit more complicated, hopefully your engine is still standard and you have an 11 1/2 flywheel, 8 or 16 bolts in a PCD of 13.125" (333mm), the bolt surface is 1.56" from the face of the flywheel housing. The bolt holes are tapped 3/8-16 UNC.Hope this helpsJohn

Sorry for the delay in responding. Have been on the road. Also, our decision on the cummins engine had changed and we are purchasing an entire pump package with a Deutz engine included. This occurred before I got your answer, so my priority had changed, as well.However, I think your answer was very good, and I appreciate your help. It may come in handy in the future.Best Regards XXX XXX Bless!
