Difference between LET862C & LET802C Engines? (I have SD1840 tractor)

[Temblor]

I have a SD1840 tractor with a LET802C engine. I was given a FORD 1500 Service Manual with it and told it was the same tractor? But the Ford 1500 shows a LET862C engine and I am wondering if there are differences major or minor in these two engines?
Fuel Injection system? Timing?
Thanks in advance for any help.

It isn't the same tractor. It is the closest model that has an English repair manual. Hard to tell how close they are without comparing part #s. There are the same series of engine with a different bore, so they should be fairly similar.

These are different engines: the LET802C has 804 cc displacement and an 80.0 mm cylinder bore, while the LET862C has 1,134 cc and 86.0 mm, respectively
