3208 CAT versus 5.9 Cummins

[davidkerryedwards]

The Cummins is a slower turning engine than the Cat. To make the swap
work, I'm almost certain that there have to be gearing changes. There
are a number of people who have swapped the Cummins into older
Travco's but they either have to switch the rear end or go with the
545 with overdrive to get decent top speed. I think the 545 is only
rated to pull 14k lbs tops.(at least that is what I have read)
Also, the later electronic 5.9's are notorious for failing lift pumps
which take out the IP when they do, since the IP is lubricated by
diesel in the later models. If you have one, put a fuel pressure
gauge between the lift pump and IP to avoid expensive repairs.
