Remove the turbocharger mounting 3 nuts.
Please do not lift the turbocharger using the actuator rod as a lifting handle.
While fitting back the Turbocharger, it is essential to
purge the oil supply line of any air
.
NOTE: Do not mishandle, tumbled, drop or keep any ports open.
Check
The inlet connection & outlet exhaust connection to turbocharger for foreign material, cracks,
blockages, sand particles, loose nuts etc. This check should be done more thoroughly if any damage
has been noticed in compressor or turbine blades as under normal operating conditions the blades
can damaged only if a foreign object hits them.
Check all the hoses and pipes from turbocharger outlet to intercooler and intercooler to inlet
manifold for crack, aging, leaks. Check the hose clips for proper functioning. If in doubt – replace. The
oil supply pipe should be checked carbon deposits, crack, distortions etc. Clean the supply pipe
before fitting. Do not attempt to change the orientation of turbocharger and ensure the correct
gaskets are used.
Do not reuse any of metallic gaskets even if they appear to be good. It will lead to leakage & drop in
the performance of the engine.
Installation –
Once a new turbocharger is being installed
a.
Fill fresh clean oil from the oil supplies port and after that give the shaft few rotations.
b.
Fit the supply pipe.
c.
Crank the engine till a steady stream of oil comes out through the drain pipe.
•
Do not crank the engine for too long.
•
Excessive cranking will result in emptying of the pump cavity causing the plunger to run dry.
This will ensure that the oil supply line to Turbocharger is purged of any air pocket.
d.
After this fit the return line from turbocharger to sump, taking care to avoid any kinks. With
engine running condition, check the air, exhaust and oil connections for leaks.
