Well I tried to up load the pics and it wont. so here are the 3 sets of numbers on right side .starting with they one inboard the most and working to the outside of bell housing... 5E26C then the middle one is 44021 G then the outside one
is C1095455G6. then on the Left side same place is this number 70A18 P and the P is twice as bib as the other numbers..I will keep trying to upload pics..other information is I have a part number of the 13" flywheel that part number is C5NE6375BB ..I looked that part number up on the Ford New Holland site and that flywheel assy. comes on a 3550/4400/4410/4500. the loader is I think 740 as I matched up my bucket to that and its the same 71.5" wide. . It has a 753 hoe . and trans mission number on top plate by shifter is C5NN-7222-C and lower left side of trans is C5NN4024H
I will keep trying to upload pics. or if you can my emaill is email@example.com...I have lots of pics of the ford and engine is removed and just replaced rear main seal. I think its a 4 speed with high and low ..unless the shifter on the right is a reverser..not a hi/low lever. . The rear of the motor behind the flywheel is shinny cast like new..never any paint ..it could be a replaement motor like you said.
