Stop
Turbo
Burn-
out!
W
ay too many turbochargers on
the engines of commercial con-
struction equipment are ending up
at support and DOL shops for
repair or replacement.
How come, you ask?
While transported on the back of
a semitrailer, the exhaust pipe on
this type of equipment can face
directly into the wind. That means
air is being forced down the
exhaust pipe into the turbocharger
during transport.
All that forced air causes the tur-
bocharger’s impeller to spin with-
out lubrication. Without oil being
pumped to the impeller bearings,
they burn out. The end result is no
turbocharger.
So how do you prevent tur-
bocharger burnout?
Use duct tape, NSN 5640-00-
103-2254, and tape over the
exhaust stack. That way no air gets
forced down the stack and into the
turbocharger.
Just remember to remove the
tape before vehicle startup.
