POWER UNIT - MULTIPLE ENGINE REMOVAL - AND RUN-IN INSTRUCTIONS
The power absorbed is measured generally in torque (lb-ft) on a suitable scale. This value for a given engine
speed will show the horsepower developed in the engine by the following formula:
Engine Horsepower = Torque x RPM
Some dynamometers indicate direct horsepower readings. Therefore, the use of the formula is not required
when using these units.
b. Test and Run-in Procedures.
During the actual operation, all data taken should be recorded immediately on an Engine Test Report (see
Certain instrumentation is necessary so that data required to complete the report form may be obtained. The
following list contains both the minimum amount of the instruments and the proper location of fittings to the engine so
that their readings represent a true evaluation of engine conditions. Diesel diagnosis test kit J 9531 contains all the
instruments necessary to carry out the various tests.
(a) Oil pressure gage installed in one of the engine main oil galleries.
(b) Oil temperature gage installed in the oil pan, or thermometer installed in the dipstick hole in the cylinder block.
(c) Water temperature gage installed in water outlet manifold.
(d) Adaptor for connecting pressure gage or mercury manometer to engine air box.
