turbochargers concerned must be returned even

if turbo does not show any visible signs of damage

to Honeywell so that the components can be

checked, in particular the condition of actuator

calibration, condition of flanges, etc.,

During quality inspection, follow the instructions

of handling.

After the inspection, replace the caps or other

protective devices inorder to avoid the

introduction of foreign objects.

Preparation for assembly on engine

Ensure the conditions of handling and installation

of turbocharger / manifold are such that there is

no risk of shocks, dropping the turbocharger or

damage to the sealing surfaces (turbine housing

inlet and outlet surfaces, compressor inlet nad

outlet , oil circuit), or damage to the actuator or

flow adjusting rod and screw which might lead

to the misalignment

Check, before connection, that the internal piping

of the manifolds and / or upstream turbine piping

and sealing surfaces are free of particles as well

as the oil inlet piping on the turbocharger. It is

recommended that the cleanliness standards for

the internal surfaces of the turbine housing of

turbo be applied to the exhaust manifolds inorder

to limit the risks.

The tightening of the oil inlet piping and the

connections must be done inline with the

suppliers recommendations as indicated in the

turbocharger drawing. Tightening torques not

specified in the drawing must be in line with

tightening standards relating to component

definitions.

Before each connection is made, ensure that any

protective caps have been removed.

Do not handle the engine unit using the

turbocharger (the compressor outlet, the

actuator, its support, housing, control rod, heat

shield or the oil inlet or return pipes) as a handle

During transport of engine after assembly inside

the plant, use protective caps for all open ends

to ensure there are no foreign objects

Preparation for engine tests

Ensure the engine is mounted very close that it

will have on vehicle inorder to guarantee the oil

supply and return.

Before the test, ensure any protective caps have

been removed.

During the tests, the 'provisional' connections of

turbo must be such that the stress imposed on

the casings are negligible

General lubrication precautions for the

turbocharger (filtering, oil pressures on starting,

time taken for the rise in pressure are followed as

per turbocharger outline drawing) are followed.

Protect turbo against introduction of impurities

when filling oil during engine start.

Engine start / green engine

Protect turbo from introduction of impurities

when filling oil

Before engine is started, it is preferable to fill few

drops of oil at turbo

The starting of a green engine must be done with

a progressive in the speed of the engine in order

to allow the oil pressure to establish itself in the

oil inlet piping and in the turbocharger's internal

oil circuit.

A starting strategy which maintains a low

turbocharger speed is recommended, to give the

oil pressure time to establish itself before starting

to rotate the turbo at high speeds. Please look at

turbocharger outline drawing for minimum oil

pressure requirement
