The following procedure assumes that the lubricating oil
and fuel systems were correctly primed, the dipstick cali-
brated, and the engine filled to the correct levels with oil
and coolant during installation of the engine into the chas-
sis. If these sytems were not serviced during installation
of the engine, refer to Engine Dynamometer Test - Instal-
lation 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 Main-
tenance Manual, Bulletin No. 3810205, for instructions on
filling the lubricating oil and the cooling systems.
The number of instruments and gauges required to per-
form a chassis dynamometer test will vary according to
the type and the capability of the test equipment used.
Refer to pages 14-4 and 14-5 for the correct system pres-
sure and temperature gauge connecting locations.
