Welcome to the Boards.

The 450E originally was a 4276T. As to what pump a 4045 engine needs that may be a question asked at your JD dealer or an injection shop. The 4045D is/was used in many applications with different pumps and settings.

If your JD Construction and Forestry dealer has a Repower book, they may be able to look up a 450E repower. I have an older JD Ag repower book and see a 2630 Ag tractor repower. That shows as having a 4276T with the repower being a 4045D, according to an old repower book I have. It shows the injection pump as option 1602 and some notes about changes needed to the pump for use in that tractor. A JD dealer should be able to find out what the option 1602 is, if they don't have 450E repower info, which could give you a starting point. Note that the 2630 uses a pull type shut off and your 450E would be electric so all the Ag changes needed won't be the same as needed for your crawler.
