All The Other
Benefits Of A
Series 60 Engine
With more than 5 different power
ratings to choose from, it’s easy to
match a Series 60 engine to the
exact needs of any coach operator.
But sometimes their needs change.
That’s not a problem with the Series
60 engine! The power chart on the
left shows the groups of engine rat-
ings within each family.
The families contained in each of
the shaded sections have identical
hardware. The groups displayed in
each family show the prepro-
grammed horsepower range in a
single engine. A simple electronic
tool is all that is required to change
power within a group. Power
changes from one group to another
within the same family simply require
reprogramming of the engine’s elec-
tronic control module.
It is possible to change power
from one group to another (just
make sure the coach cooling, air
intake and exhaust systems and
the driveline can handle the
change). Upping the horsepower to
the maximum limit at time of
trade-in is an easy way to increase
both the resale value and
desirability of any coach.
