Looking at the photo of the rear end I'm thinking that is a 3500 not a 4500.
3500 would be a 3000 series with a 175 ci diesel and not the 201 that is in a 4000 chassis.
You had best look at it and let us know which one it is as the injector pumps will be different.
The pump you want fits 3000, 3400, 3500, 3600 "I think" based upon that rear photo.
Look under the right side hood for a foil tag for the numbers - model #, tractor #, etc.
Or if the foil tag is not there the numbers will be Stamped into the top of the transmission - on a flat spot, just above and behind the starter. See photo. You may have to scrape off some crud, dirt or paint to see them. Does no good to go about it half Fast so make sure you get the numbers correct.
Post them here and we can tell you exactly what you have.
No special tools needed to change the pump.
Remove the gear cover on the front of the timing cover. Remove 3 bolts that bolt the gear to the pump shaft. The gear is indexed to the pump shaft with a pin - can only go back on one way. The gear is held captive in the timing cover - can not skip time.
Disconnect all injector lines and remove them from the tractor completely.
Look at the second photo - you will see the timing mark on the body of the pump and the marks on the engine. Make a mark or take a photo of which line it is set to. Usually about 1/2 line below zero but might be different.
Remove 3 bolts that hold the pump to the engine - tough to get at the back one but can be done with the right combination of socket extensions and swivel.
Pull the pump and install new one in reverse order.
Very easy job.
PS,
Tractor probably weighs in the 7000 plus range.
