I am wondering what is the difference between JD 4024tf281 and JD4024hf285 engines. How to find if they are interchangeable?
The 2 engines in question , are they from a similar application ex: generator.? Any serial numbers for the 2 engines ?
I only have one serial#PE4024L094610 it is on a 6" trash pump. It is the hf285. The other one is off a generator I believe. It is the tf281 model
The ”H” in HF285 means the engine installation is designed to include an air to air intercooler. I took (2) screenshots from the Deere engine build data site using your provided serial number. The HF285 is rated at 80 HP at 2800 rpm. . From what I can find a TF281 genset engine (Fixed at 1800 rpm) is only about 50 HP. .
I have records of a 4024HF285 on a customer genset. So it looks like that arrangement could work for you. I don't know if the ECM would need adjustments or what. It has to somehow be fixed at 1800 RPM.
So that engine will be a little shy of the power needed for the 6" pump. I appreciate the information, Thank you
