Does anybody have any idea how hard it is to install a new oil pump. Machine has no oil pressure or flow from the filter housing. Machine has 1400 hours and has set for 3 years. My grandson bought it for his wood cutting business. Engine runs but shuts down due to low oil pressure.
Thanks

I would test the oil pressure switch, electrical and oil system with a mechanical guage before tackling a major. More than likely an electrical gremlin or stuck sensor after sitting for so long.
That being said, they're not horrible to change. Just a bit in depth and time consuming. Case & New Holland are essentially the same machine with some mechanical & aesthetic differences. Do some research into whether you are mechanically capable of the endeavor before digging in.
The case new holland parts store (https://www.mycnhistore.com/) should help a bit. Your machine is basically a case 445 series 3 or case 450 series 3 with the same 445T/M3 engine.

Checked by procedure and no pressure, also pulled switch and turned motor over, still no oil or pressure, pulled filter housing/cooler cover started machine and no oil flow, should have made a big mess. I don't have shop manual but it looks like the pump can be changed without removing engine??? Thanks for you help!

Just drop the belly pan under the engine and pull oil pan and the pump is easy to change
