Turbocharger -
Turn impeller (4) by hand.
The impeller
Continued
should turn freely.
If the impeller scrapes
the casing wall, or if the impeller shaft
binds, the turbocharger must be replaced
or repaired.
Check the turbocharger connections to
suction pipe (5) and exhaust manifold (6)
for loose or missing hardware, signs of
leaks, cracks, or other damage.
·
Check that exhaust manifold (6) and suc-
tion pipe (5) assemblies are securely
mounted to the engine block.
The turbo-
charger is mounted on these assemblies. If
they are loose, vibration will damage the
turbocharger.
Position air inlet (2) on the turbocharger
(3) and tighten hose clamp (1). Be sure
air inlet seats squarely on inlet flange (7)
and there are no air leaks after the clamp
is tightened.
·
Inspect oil lines (8) for loops or kinks that
would restrict oil flow.
While the engine is operating, inspect
turbocharger oil lines (8) for leaks, and
listen to the turbocharger for noise. Ob-
serve exhaust for discoloration.
