Visually inspect the engine for coolant leaks.

Repair all leaks found.

The intake air piping must be plumbed through an af-

tercooler to control the temperature of the intake air dur-

ing the run-in procedure. Rig an aftercooler beside the

engine, and plumb the intake pipes from the turbocharger,

through the aftercooler and back to the intake manifold.

Use a temperature gauge to measure the intake manifold

temperature.

NOTE: Maintain the intake manifold air temperature at 66°C

[150°F] or below during the dynamometer testing or run-in;

if manifold temperature exceeds this limit, terminate the test

and idle the engine to let it cool down. Do not idle more than

10 minutes. Testing can resume when the intake air tem-

perature can be maintained below 66°C [150°F]. Under no

circumstances is the intake manifold air temperature al-

lowed to exceed 77°C [170°F].

Install a water manometer to the air inlet pipe of the

turbocharger to measure inlet restriction.

NOTE: The manometer adapter must be installed at a 90

degree angle to the air flow in a straight section of pipe, one

pipe diameter before the turbocharger.

NOTE: A vacuum gauge can be used to record the intake

air restriction.

Minimum Gauge Capacity: 760 mm H

0 [30 inches H

0].

Install a mercury manometer to a straight section of the

exhaust piping near the turbocharger outlet to measure

exhaust restriction.

NOTE: The manometer must be scaled to record exhaust

back pressure in excess of 75 mm [3.0 inches] of mercury.

NOTE: A pressure gauge can be used to record the exhaust

back pressure.

Minimum Gauge Capacity: 254 mm Hg [10 inches Hg].
