Opened up my swing rad....

[Eric Johnson]

Hi Scott,
My understanding from diesel mechanics and from the Cat manual is that the
engine can
operate without damage at wide open throttle and without a load. I have done it
from
time to time to for short periods (we're talking 15-20 seconds) and no parts
flew off.
Does make me cringe but the 2800 rpm is straight out of the Cat manual for 3208
engine.

Diesel engines can run away if they get an uncontrolled source of fuel (like
lube oil) but as
long as your governor is functioning this should not happen in normal
circumstances.
Regards, Eric
