NOTE

Be sure the exhaust manifold remains seated on the locating

pads on the cylinder head.

Follow-on Maintenance.

(1) Connect air inlet elbow to turbocharger (see para 4-128).

(2) Connect exhaust outlet pipe to turbocharger (see para 5-44).

(3) Connect batteries (see para 4-114).

NOTE

The lube oil supply connector formerly installed in the plate is

now assembled directly to the turbocharger center housing. The

oil inlet of current TV turbochargers is being threaded by the

manufacturer.

(4) Start engine and run at idle for ten minutes. Engine oil pressure should register at 10 PSIG on the

gauge in the cab.

CAUTION

Do not hold the compressor wheel, for any reason, while the

engine is running. This could result in personal injury.

(5) Check turbocharger gaskets and ducts for leaks.

CAUTION

If any such noise is apparent, stop the engine immediately and

determine the cause.

(6) Operate the engine at rated output and listen for sounds of metallic contact from the turbocharger.

CAUTION

After the turbocharger has been operating long enough to permit

the unit and the oil to warm up, the rotating assembly should

coast freely to a stop after the engine is stopped. If the rotating

assembly jerks to a sudden stop, the cause should be

immediately determined and eliminated.

(7) Shut off engine.

(8) Install engine enclosure (see para 4-127).
