Procedures
(Chassis
Dynamometer) (14-05)
The following procedure assumes that the lubricating oil
and fuel systems were correctly primed, the dipstick
calibrated, and the engine filled to the correct levels with
oil and coolant during installation of the engine into the
chassis. If these systems were not serviced during
installation of the engine, refer to Engine Dynamometer
Test - Installation of the Engine (14-01) for instructions
on priming the lubricating oil and the fuel systems and
calibrating the dipstick. Refer to the latest B Series
Operation and Maintenance Manual, Bulletin No.
3810205, for instructions on filling the lubricating oil and
the cooling systems.
The number of instruments and gauges required to
perform a chassis dynamometer test will vary according
to the type and the capability of the test equipment
used.
Refer to pages 5-318 and 5-319 for the correct system
pressure and temperature gage connecting locations.
To correctly monitor an engine's performance, record
the following parameters:
Lubricating oil pressure (vehicle instrument panel)
Coolant temperature (vehicle instrument panel)
Coolant pressure*
Intake manifold pressure*
Inlet air restriction*
Blowby*
Engine speed (RPM) (vehicle instrument panel)
* See the following for the Service Tools required and
the installation locations on the engine.
Measure the coolant pressure at the cylinder head, rear
fuel pump side.
